NF Acous NA20 Review

Intro 

Hello everyone, this review and feature covers the latest from NF Acous Audio (formerly NF Audio) named the NF Acous NA20 ($118). I was very happy to find out I’d be able to hear this set, for a few reasons, but mainly because I’m interested to see what’s out there within the $100-$150 price point. In my opinion it’s easily one of the most hotly contested ranges in audio and a set which can stand out in this range is truly a special iem. Another reason is because the NA20 is a product from the former NFAudio which I always had a lot of respect for. I haven’t actually heard one of their products in quite some time and so needless to say my curiosity got the best of me. Especially since the NA20 happens to be part of the “Musical Series” of iems from the brand. I had to hear them.

NF Acous 

I’ve had a little bit of experience with NF Acous or NFAudio iems in the past. I’ve spent quality time with the amazing NFAudio NM2+, NFAudio NM2, NFAudio NA2+, and the NFAudio NA2. However, that was at least a few years ago. I definitely feel that each of those could still hang with what’s out in the market now, per their respective audiences for each set. At any rate, I like the origin story here. NF Audio was actually founded way back in 2014 by Felix Yang. Apparently, Felix was so taken aback when he was a very young 17-year-old teenager by a pair of Hi-fi iems. Aren’t we all. Anyways, it was with that pair of iems that his passion was ignited. This passion fueled his desire to learn and grow in the area of mixing & recording which turned into a lifelong pursuit. Oh, how well I can relate. Well, maybe not the mixing and recording experience, but definitely in the passion. It’s a cool beginning and it’s a story that I can certainly get behind. At any rate, fast-forward past years of NF Audio success and in 2024 Felix renamed NF Audio to what it is now “NF Acous”. Nothing like a fresh name change to regenerate some of that fire. 

Competition 

Without question the NA20 has some serious competition within the loaded Audioverse. Like I said earlier, the $100 to $150 price point almost has no end to the number of talented products which encompass this range. Just take a second and go over some of the iems. It’s actually quite silly. Now, I just received the NA20, and I have gotta tell you folks… There’s no way I’m not reviewing this set. I definitely feel it has the sound to carve a path for itself and it’s a set which will most certainly stand out to the right hobbyists. Obviously, nothing is for everyone and everything is for someone. However, I think the NA20 has a shot at being that perfect sound for those who desire its certain type of musicality. Without the shadow of a doubt NF Acous crafted a very nice sounding unit. That said, I can also tell you right now that it won’t jive perfectly with everyone as it certainly has a specific tonal character tuned towards those who enjoy that more energetic, smooth, and musical sound. Perfect for those who enjoy the emotion extracted from their music. So, without further ado… the NF Acous NA20 everyone…

Packaging / Accessories

Unboxing 

The box that arrived at my home is rectangular, almost square (6” x 5” x 3”). NF Acous made sure to add that beautiful amber colored hue to the sleeve cover along with touches of black. You’ll see a graphic of the NA20 on the cover as well as some highlights of the product, some specs in the back too. This is one area where NF Acous does a very nice job. They always have nice unboxing experiences, very unique to them. Anyways, the box is nice to look at. So, the graphics and art are actually on the outer sleeve. Take the main box out of the sleeve and you’ll notice that it’s actually two smaller boxes folded in half with a connector and held in place by a small magnet. Unfold both boxes. This is where NF Acous kind of separates themselves from the pack because it is such a cool design that they’ve come up with. On the left is a holder of sorts for the carrying case as well as the manual. But on the right is this dope looking “CD” layer of cardboard covered foam which holds the NA20 in perfect cut-outs. It’s a slick look. Take out the “CD” style layer and under it you’ll find the rest of the accessories. Mainly the eartips which also sit inside of a “holder” of sorts as well as the 6.35 to 3.5 adapter. Anyways, they did a nice job for the price point. It’s creative, nice to look at, and it sets the tone for the consumers overall experience. Nice work NF Acous! 

Stickers! 

Ooh, one last thing. NF Acous was wonderful enough to add the awesome sticker pack in what they sent me. What an awesome little add-in to the packaging that I was in no way expecting. I loved seeing them. So, the stickers will go to the first who order the NA20 until they run out. I love these and I’ll surely put them… somewhere. 

Eartips

As I said, the eartips which came packaged with the NA20 come in a black cardboard “holder” of sorts. There are four eartips in total with four different sizes (XS, S, M, L). The eartips are all white silicone with a shallow fit and a wide-bore. They aren’t bad by any stretch and certainly are usable for me. However, the flange is a bit too flimsy for my ears. I need rigid flanges to get a seal. I cannot have flanges which are flimsy, they need to have structure to them. This is why I love the KBear 07 eartips. So, I had to tip roll for the NA20 to fit nicely and actually seal well. What I went with are a pair of eartips very similar to the KBear 07’s. Only this pair has a green inner stem. Pretty much identical to the 07’s. Having said all of that, the included tips really aren’t bad at all, and I understand why NF Acous provided them. It makes sense to offer a wide bore set of eartips for a set like this. I personally feel that a semi-wide bore is actually the sweet spot for this set, but that’s just me. 

Carrying Case 

NF Acous also added in a fairly small carrying case into the packaging. I actually like the size of this case as it is great to put in a pocket and not have to worry about it bulging out too much. However, the case is just large enough to snugly fit the NA20 earphones as well as the included cable. Using a fatter cable makes it a titch harder to close, but it works too. Anyways, the case is not large, and it’s covered in a fabric style black cladding, opens in the middle and has a zipper to securely shut. Inside you’ll see a mesh holder as well. I could see some folks complaining about the size and that makes sense. You certainly aren’t adding in any other accessories into this case. No extra cable, maybe an extra set of tips, but definitely not a dongle dac. It’s very nice looking, with a nice build, but the size may throw some people off. I like it. 

Cable

The included cable is one which I’m sure was added in the name of functionality and not for its aesthetic qualities. I’m just going to say it; it’s not the best-looking cable I’ve ever seen. You see, it’s extremely thin and very rubbery feeling as well. It’s the type of rubber which feels sticky to the touch. The cable has a twist instead of a braid and it really does NOT do any justice to the NA20. So, the cable provided is a 2-pin QDC style cable that ends in a 3.5 single ended jack. It’s said to be made of 6N pure OFC (oxygen-free copper) copper and has a gold-plated plug. So, it isn’t the most pleasing to the eye in my opinion. Of course, I needed to upgrade the cable to fit my 4.4 sources. I actually went with an Artti modular cable. It looks nice paired with the NA20. I think anything brown, white, black, or closer to amber in color will work great aesthetically. The Artti cable seemed to pair best. Still, in the end, the included cable works wonderfully for what it’s for. As I said, I think NF Acous used this cable for its lightweight design which is usually preferable for onstage users. Also, the NA20 are extremely light in weight themselves, which makes sense that you don’t want some super heavy cable weighing them down or pulling them out of your ears. So, I get it. I just don’t enjoy the look with this beautiful set. 

Build / Design / Internals / Fit 

Build Quality 

NF Acous states that they used a high strength polycarbonate resin to form the NA20’s shells and faceplate. The nice thing about this resin is that it helps the NA20 to be extremely light in weight, which makes it great for wearing for long periods of time. Obviously, we’ve seen hundreds of all resin sets and so using this material is not a novelty thing. What is rather “novelty” is how well the fit is. I can see that NF Acous had the presence of mind to add a slight angle of the nozzle for the inner ear as well as a nice hump for support. Of course, it also says as much in their promotional material. The point is that the NA20 is very comfortable. The nozzle is right around 6mm in width and doesn’t reach too far into the ear. I’d say medium length (what’s medium Chris?). NF Acous made the nice decision to use alloy for the nozzles themselves, and I think it’s a nice look. You’ll also notice two vents on each earphone. One small vent in the front cavity and one in the back. Also, NF Acous decided upon QDC style 2-pin connectors. This is one thing that I wished they would’ve reconsidered. However, it’s no deal breaker. I honestly feel the build is quite nice. Like I said, the NA20 is all about long listening sessions and comfort and they feel like nothing in the ear. It’s quite an awesome thing to have such a featherlight earphone which sounds as powerful as the NA20 does. 

Build cont… 

I don’t want to overspeak the situation here, but I’ve come to appreciate something which is functionally adept, something that prioritizes ease of use and there are a few brands which do well in this regard. That’s definitely NF Acous and it’s definitely true for the NA20. Also, the polycarbonate resin is very hard. I don’t know how else to say it. I feel if I ran a knife across them, it wouldn’t even scratch the NA20’s shells. However, in the end we’ve all seen plenty of resin iems. We get resin sets at $25 anymore which aren’t built any worse “structurally” than $900 resin sets. So, the NA20 won’t bring anything to the table which will blow your mind or anything, and you will probably hear someone calling the build cheap. For the record, I don’t feel this is a cheap design… at all. It’s a smart build, a functional build, and it’s a professional build. They did a good job. 

Design / Aesthetic 

As far as the actual design, the looks, and the overall aesthetic in conjunction with the build, I’d say that NF Acous made one of the cooler looking sets built in this way around this cost. It’s a simple design and a simple concept behind the appearance too. Keep things simple, stay classy, and craft a set that isn’t overly adorned in ornate decoration. Sure, ornate and heavily decorated sets are fun sometimes and some brands pull it off very well. However, some of the time an overly designed set looks gaudy, and sometimes even ridiculous. Keep it simple. Well, that’s exactly what NF Acous did. The NA20 has gorgeous transparent amber shells which enables me to see all the inner workings inside of those shells. I love that they had the presence of mind to keep that same transparent amber resin on the faceplate too. It’s a cool color and a color we don’t usually ever see. However, there’s a few things which contrast that transparent amber resin perfectly. That is the gold-colored aluminum border which corals the faceplates, the gold-colored logo on the center of the faceplates, and the gold-colored aluminum nozzles. It is such an awesome color combo, in my opinion. Now, I’m sure you’ll have your detractors and those who’ll say that the design is kind of boring. Yet I couldn’t disagree more. I think the NA20 earphones have a handsome design, and an almost elegant design. Let’s put it this way, the NA20 looks pretty darn cool in the ear. Nice work NF Acous. 

Internals

NF Acous decided that the NA20 was going to get a fresh new driver within this set and the driver that they decided upon is actually quite nice. At least to my ears it is. Now, we don’t know much about this new driver as there simply isn’t much written about it. However, I can tell you it is their brand new MCL2-100M beryllium-plated dynamic driver. I don’t know the size, magnetic flux info, and a host of other questions are mostly unanswered. Nevertheless, I don’t really care either. Who cares if it sounds good? Let me answer that… um… nobody. In my opinion, the driver selected to take up the mantle as NF Acous’s “Music Series” driver is actually a very clean sounding, organic sounding, and also a very composed driver. Internally, NF Acous gave the NA20 a dual cavity which is great on many fronts. However, what they did was they updated the sonic cavity adding their SRA (selective-reflection-adjustment) technology which is employed to reduce the reflected sound using up to five pressure damping nets as well as two tuning sponges (tuning foams). This is meant to adjust the pressure between both the front and back cavities. I assume this is how they could give the NA20 such a bass and treble emphasis yet somehow the sound comes across relatively balanced dynamically. Nice. 

Fit / Comfort 

What do you think I’m going to say here? Obviously, I feel the NA20 is one of the more comfortable iems in quite some time. The fit for my ears is stellar as once I found the right tips and got the right seal, I was very happy. I’m a long listening session reviewer folks. I like diving into a set, soaking it in, and listening to massive amounts of Playlist tracks. I want comfort. Now, I should also add that most iems are fairly comfortable for me. Still, the NA20 brings this to the next level with its smaller frame and the very lightweight build. Also, the Shells are very ergonomic, and I’d think they would fit most people in a similar fashion. 

Drivability / Pairings 

Output Power 

The NF Acous NA20 is rated with an impedance of right around 32 ohms and a sensitivity of around 109 db’s. Without question the NA20 is very sensitive and easy to drive to proper volume and dynamics. Friends, this set sounds great off of almost anything. I paired the NA20 with everything I have, every source at my disposal. That means, three or four cheap 3.5 single ended Conexant Amazon dongles (<50mW @32), three different Android smartphones, my iPad, the KZ AN01, KZ AZ20, and the Fiio UTWS5. All of those devices are low output sources, and each one drives the NA20 nicely. No issues whatsoever. So, if all you have is a smartphone with a 3.5 port then I think you’ll be in business for sure. It doesn’t take much for solid sound out of this set. 

It scales well

Having said that, I have to report that the NA20 definitely scales with power and source quality. Most definitely the bass will tighten, it’ll sound more vibrant, feel punchier, and simply just come across a hair more defined with more power. Midrange notes sound less restricted, more open, clearer, with the same nice note body. They’re still smooth and wonderful, but they also gain some crispness too. A little more fine-lined precision. Also, the treble is less splashy with a better-quality source that can add some juice. Now, I’m not talking about the best and most powerful desktop source either. Yes, those sources will sound amazing, but I’m talking about a solid dongle dac. That’s all you need. When I say solid, I mean something as low in cost as the EPZ TP35, the Shanling UA6, the EPZ TP50, Simgot Dew4x, or even Bluetooth dac/amps like the IFi Go Blu or the Shanling UP6. I know because I used each one of those fairly extensively. The TP35 can provide around 170 mW @32 ohms, for instance. I find using these dongle dacs with their 4.4 balanced port and flipping them to high gain worked nicely. Of course, my more powerful sources with better circuitry took things up a notch as well. So, there’s definitely room for the NA20 to scale in sound quality. Despite that, the NA20 doesn’t “require” a ton of power, and I find that great. 

Sonic Pairings

The NF Acous NA20 has what I’d call a warm/neutral lean to the sound with some nice treble brilliance which adds some luster up top. The warmth comes from the boosted bass region, but that bass isn’t a muddy bass, thankfully. So, a warmer source doesn’t really embellish that warmth making the sound less precise or more congested. Which at least somewhat goes against our understanding. That said, I do feel a brighter source does add a bit more splash and treble glare at times. However, it depends. I wouldn’t call the NA20 a “chameleon”, but they are fairly well adept at many different tonal Pairings. Of course, what you enjoy will come down to you. Nevertheless, in my most honest opinion I enjoy neutral to warm/neutral sounding sources with the NA20. I enjoy a source with some nice dynamic energy with the NA20 too. For instance, the best sound I heard out of the NA20 came from my Shanling M6 Ultra, and the Fiio Q15. Both are warm/neutral, both provide some nice dynamic contrast, and both devices have loads of power. Ya know what, I like most of my sources with this set. I simply don’t enjoy any bright sources as much, and I don’t enjoy bland sources with the NA20. That’s it. The NA20 should mesh well with most any source made nowadays. Most of them are neutral to warm/neutral anyways. 

What do you need? 

Like I said, in my opinion, you should try to get a simple dongle dac if you can. I realize not everyone has the disposable income to drop on a dongle dac, but if you can, it’ll pay off in your listening sessions and the NA20 will reward you. However, if all you have is a smartphone, don’t fret because the NA20 doesn’t need much to sound great. 

Sound Impressions 

*Note:  I want to preface this entire section with a few quick notes. First, I put the NA20 on the burn-in station for four full days. The NA20 has a beryllium-plated single dynamic driver and in my opinion, it does help to give this set some run-in. Usually anything beryllium could use some. Now, I don’t know if four full days is necessary, but I just let em’ go and when I decided enough was enough the NA20 seemed to sound a hair more controlled, seemingly tighter, less bright glare up top. Also, I listen entirely using flac or better files which are stored on my devices. I simply prefer those nice files. I use different eartips then those which come packaged with the NA20 too. Those being some KBear 07 clones. Very similar to them. Lastly, the Androud music player of my choice is UAPP (USB Audio Player Pro) as well as Eddict Player and Hiby Music Player for certain dongle dacs. 

Single DD 

Single dynamic driver earphones have a sweet spot in my heart. They can be so diverse, yet also so simple. Single DD’s can also provide some of the most compelling and rich listening experiences. In an age where tribrids, quadbrids, and multi-driver sets mixed with all sorts of driver types own the hearts and minds of most audio enthusiasts, I find it funny that the good ole’ faithful single DD’s can still outperform those sets rather easily in many regards. No doubt I enjoy any driver configuration if implemented well, but this is a short & quick ode to the most ancient driver type. I will always love them. I think we can all agree that the most impressive aspect of a single DD can be their timbre, natural sound, their unified coherency and soundstage which usually promotes a very organic but also visceral listening experience. Also, a single DD can even mimic a multi-driver set when tuned right. Of course, single DD’s also have their limitations to a degree as well. I think we find this in the NA20. Both the pluses and some of the limitations. While it (NA20) is very special in many regards, it still has some slight preferential issues which can arise. Undoubtedly, the NA20 takes on the essence of a single DD exactly as expected and does so very well per its particular style of tuning. That style of tuning promotes a very immersive and very engaging experience. Let’s check it out…

What’s it sound like? 

Folks, the NF Acous NA20 is a $119 single dynamic driver earphone. So, we at least “kind of” have an idea of what not to expect, to a slight degree. What we should expect is a more cohesive sound as all areas of the mix work in concert, homogenized, and a more analog sound then you’ll generally hear from other driver types, multi-driver sets, hybrids etc. I said “generally”. Of course that isn’t always true. From what we know the NA20 is supposed to represent a musical take from NF Acous’s more reference set, the NFAcous NM20, and I’d say that NF Acous absolutely nailed that vision. However, with that musicality the NA20 didn’t entirely lose the fine-lined technical capabilities found in the NM20. To me, the NA20 has a fun sound, it’ll move your feet, a nice set to work out with, to go running with, to clean the house with. It’s all those things. However, this is also one fantastic set to simply get lost in your music with as well. No doubt there are things that I would’ve liked to change a bit and I’ll outline those things as best I can. However, at the end of the day the NA20 should fill a void that many hobbyists are seeking in their listening sessions. No doubt it won’t be for everyone, that’s for sure. Despite that, who this set is for…those people will probably love it!

Warm influence 

In my mind the NA20 carries a “version” of an organic sound, yet with a dense low-end and a sparkly flare up top. There’s definitely some color to the sound. The sound is this sweet and wonderful kind of perplexing to me. On one hand it’s fun, almost rambunctious, and yet on some tracks I almost hear a relaxed, smooth and easy sound. The NA20 also most certainly has some cherry-on-the-top type of treble energy to it. That energy is undergirded by this foundational and heavy bass. To be perfectly honest I’ve found it hard to describe this set in a way that I’m truly happy with. In my pages of notes there’s a lot of contradicting statements. Let’s see if I can make some sense here (probably not). To me the NA20 is warmth infused into a neutral underbody and that warmth comes to us from a very swelled bass region. In addition, there’s also this tinsley, resplendent, and brilliant treble energy. However, even with that treble lift there’s still a warm tincture cast across the spectrum. Basically, the bass warmth influences the tonal coloration of the NA20. So, this is why I call it a “version” of an organic sound. It has the fundamental hues of an organic sound, but it also has plenty of contrasting vibrance too. The NA20 can be atmospheric, it’s very full, it can be pretty dynamic too with a solid helping of macro-dynamic energy and a nice tonal contrast. It’s definitely got its issues (like anything), but the good definitely outweighs the bad. 

Off-Natural

With all that said, let’s just get one thing out of the way now… this is not a perfectly natural sounding set. I’m sure you’ve gathered as much. Of course, that’s not a bad thing either and I suspect it’s exactly what NF Acous was shooting for being that the NA20 is their more “musical” version of the NM20. If I were to call the NA20 anything I’d say it’s definitely V-shaped. A 13-14 dB bass shelf and a majorly lifted treble region flank the ends of the spectrum while the midrange sits in the valley of the “V” (to an extent). Having said that, the midrange is not overly recessed into the flat monotone recesses of a typically recessed V-shaped sound. In fact, to my ears I’d call the midrange neither forward nor recessed. Having said that, the bass and treble most certainly share the emphasis spotlight. To unravel this further, the midrange can come across with awesome presence and sound very well positioned serving as the spotlight on many tracks, very easily. Now, you will hear some sibilance, you will hear some congestion in complicated tracks, and you’ll even hear some splash in the upper treble at times. However, you’ll also hear a very fun sound which never ceases to inform my auditory cortex, which informs my emotional response, which informs my feet to move and my head to bob in recognition. I can say that because I did just that on many occasions. However, once again, I wouldn’t call the NA20 natural. If anything, it’s “off-natural”, a version of natural, and it does so in such a smooth and fluid demeanor. Musicality is how the NA20 identifies itself. Musicality is its greatest attribute. Better said, “musicality” is the NA20’s superpower. Again, it certainly has its issues, but from my perspective the NA20 has a perfectly carved spot within the audio zeitgeist, and it fits that “spot” very nicely per the price point. 

Bass Region 

The low-end of the NF Acous NA20 has a large lift adding a very healthy dose of authoritative and booming bass. As I said, the bass shelf provides a meaty 13-14 db’s of bulbous bass making this one hard hitting low-end which comes across both satisfying and even somewhat orderly, crisp and kempt. I wouldn’t call the low-end a “basshead” style either. I realize that 13-14 db’s sounds like a lot and believe me… it hits HARD! That said, the NA20’s bass region is still at least partially balanced with the highs. Enough to offset the bass bullishness. On the flipside, I also wouldn’t call the NA20’s bass region ultra detailed or perfectly defined. This is another case where I’d say that “per the amount of emphasis” provided it has a clean playback. We’ve heard those ultra snappy, hard punch, clearly defined, well separated and wholly agile bass replays and I’d definitely say that the NA20 is not that. It’s too big for that. It couldn’t be that. Not for a $119 single DD anyways. However, it does have a very clean and very convex punch down low. The crest of each note on attack is softened, not rock hard, but it’s clean (for the most part) and decay through sustain is tight in respect to the bulbous nature of the bass. Man, I hope this makes sense to you. Basically, the bass doesn’t get tripped-up too easily and it isn’t what I’d call an overtly muddy bass. I can tell you with 100% assurance that I definitely dig this bass and enjoy what it provides to my listening sessions. 

A few more things… 

A few more things concerning the bass. There is most certainly a long and drawn-out bleed of the bass into the midrange. For many people this is a no no. For me, I’m more concerned with the overall cleanliness of the midrange and on the NA20 that isn’t something I need to worry about. So, while the bass bleeds pretty heavily, it also doesn’t make it a veiled or murky environment for the mids. What it does is adds some weight, adds richness, adds warmth, and adds that off-natural and colored sound. Also, transients within the bass region sound natural to me. They aren’t super tight with clipped harmonics, and they don’t lag either, they’re natural. I’d say that to an extent you’ll hear that atmospheric decay that so many people enjoy. You’ll hear just enough lingering harmonics and resonant air. Lastly, as I said earlier, the initial attack is somewhat softened, yet it has a dense body making the NA20’s bass region very smooth, but also very meaty. I also don’t hear anything I’d call “pillowy”, and certainly nothing hollow. By all measures the NA20’s bass replay is very nice for what it is and for who it’s meant to indulge. 

Sub-Bass 

What’s a good bass region without that grungy, gravelly, and vibratory sub-bass? The NA20 has plenty of that. This is definitely the type of sublevel rumble which provides enough haptic recognition, or haptic feedback that you can actually feel. It provides some palpable texture to a gritty bass guitar, the tacky snap and hollow boom of a kick drum, and it replays double bass very nicely as well. I should mention one more time that this is not a basshead caliber sub-bass, but in the same breath the extension down low is evident. For instance, “Can We Go Back to Bed” by Bazzi offers a heavy bass drop and bassline. With the NA20 it comes across with a very prominent, jutting, and protruding sublevel fullness and depth whilst never smearing the mid-bass to a detrimental degree. There remains a sort-of “separation” between the frequencies. The point is that the sub-bass can BANG without sounding sloppy. Of course, we all have different opinions on what “sloppy” is. For me a sloppy bass sounds smeared and that is not as prevalent with the NA20. Another track I always use for this purpose is “Groove” by Ray Wylie Hubbard. Such a groovy, rhythmic and totally jazzy track, but the bassline is flat-out stout. With the NA20 it’s definitely substantial, it has prominence, with a deep pitched but also a tactual & corporeal physicality. Basically, it’s dense and I can feel it.

Mid-Bass 

The mid-bass can certainly slam and in my opinion brings all the fullness that any track or genre would need without the blatant mud which can surround a heavy mid-bass. That said, the NA20 isn’t without some bloat from time to time. It’s a pretty big bass and it kind of goes without saying that some instrumentation will sound somewhat masked and that you will have some smearing going on. No, the NA20 isn’t going to compete technically with a Simgot EA1000, Hiby Yacht 10, Fiio FD15 or any other less enhanced single DD bass replays. The NA20 instead has that profusely swelled slam which does keep pretty tight reins on the note control for such an emphasis. Again, not sloppy at all for what it is. To be 100% honest (and I always am), I don’t feel that I hear what the graph is proclaiming about the NA20 down low. Yes, it’s big, but it doesn’t come across that big (13-14 db’s) to me when in the ear. The NA20 offers a very fun, very full, and very rich bass region and each slam is met with a clean attack along with a natural decay. But it doesn’t sound like it’s going to shake my eyelids or anything. The NA20 mid-bass has enough of a lift to add fullness to the bass guitar, meatiness to a heavy bass drop, but at the same time it can also take on some quicker bass passages fairly well too. Tracks like “Muse” by Hysteria is one such track. The NA20 sounds decently fast on this one whilst also sounding dense and full. Another track is “Kids With Guns” by The Gorillaz which offers a crisp electronic bass drop that sounds very clean, rounded, vibrant in its attack and a tight definition. 

Downsides to the Bass Region 

No doubt there are a few things that won’t be enjoyed about the NA20’s bass region. Obviously, there are plenty of fellas and ladies who won’t enjoy the type of bass shelf that the NA20 was tuned with. Also, there are things about the low-end which could be slightly improved as well. I’m sure a slightly less intrusive bass roll-off would tighten things up even further adding more of a contrast in tonality and slightly cleaner mids. Though I’d also say that you’d lose some of the musicality which defines this set. However, exactly as it is I find the bass to be very well behaved considering the lift we get here. However, those fans who only enjoy a snappy, tight bass with minimal emphasis and no bleed I to the mids are obviously not going to jive with this set. Those folks will call the NA20 muddy, maybe even bloated, not as defined as sets they enjoy. So, as always everything comes down to preference. I happen to think that NF Acous truly nailed what this series is all about. 

Midrange

The mids on the NA20 are unashamedly very intimate, very smooth, with a semi-lush feel to them as they excel at drawing out the emotion from my music. Listening with this set it has this quality which draws you in. The midrange on the NA20 is the type which isn’t trying to be the center of attention, yet somehow, they can be just that, especially in vocal centered tracks. The NA20 has the type of midrange that we in the hobby love to call musical. Granted, there’s no real quantitative way to establish that. In any case, I would certainly agree with that statement. Definitely musical before anything else. Like I said, they’re more plush, semi-rich in body, with a type of fullness to the sound that also comes across fairly well textured per the tuning. Not sharp or abrasive but textured enough to feel the body of a note. Along with that warm & semi-rich note body is a certain vibrance, a touch of vivacious energy, some crispness and some bite. The NA20 can be euphonic, harmonious, and can be straight up symphonic at times too. You have the body and warmth gifted from the low-end and the sparkly vibrance which comes from the boosted treble.  Beyond that, there’s a clarity and macro-resolution which feels vivid along with a well dimensioned sound field helping the mids come across really delightful. 

Technically Inclined? 

Of course, in the face of that very engaging sound you also have a set which may not be as technically inclined as some more articulate and detailed sets. This should be expected. The NA20’s midrange is not one of perfect resolution and so those who greatly desire extreme transparency may feel they are lacking a bit. No doubt this set is for those who greatly desire something melodic, fluid, completely and utterly rhythmically-inclined as well as unabashedly fun over analytically precise, clinically fastidious, or crystalline. Now that I’ve said that I want to also say that the NA20 holds its own technically, for what it is. I simply want to get across to the detail lovers that the NA20 will not highlight every subtle micro-detail or micro-dynamic volume shift and the NA20’s bass region will mask over certain midrange instruments at times. The sound is richer than it isn’t and while there is some air and openness, the NA20 cannot escape its undeniably engaging warmth and smoothness. Nor would I want it to. That smoothness after all is exactly what makes the NA20 such a nice set at this cost. However, that smoothness also can slightly blunt the precision in some tracks. I say all of that but there are some tracks which sound wonderfully detailed with the NA20 too. Just a few things to keep in mind. 

Further notes on the mids… 

What I really like about the NA20’s “smoothness” and “warmth” in its midrange is the fact that it’s still clean and has great energy, even in that warmth. Nothing boring here, nothing grainy, no fuzz outlining each note, no veil making the midrange feel like it’s in a tunnel. I hear some tonal contrast, some dynamism and I’d also say that even with the warmth, I hear plenty of crispness, some percussive snap, plenty of edge. I also love that this is a V-shaped iem yet it has a midrange which doesn’t really sit “back” in the mix. In fact, I’d say the mids are close enough that I wouldn’t argue with anyone who called it U-shaped. Whatever you call them I can report that the midrange has very nice presence against the rest of the mix so long as the track isn’t too complicated. Certainly not mid-centric, but vivid enough to carry a tuneful melody without that melody sounding suppressed or attenuated. Now, I do hear the faintest beginnings of some sibilance at times. Especially near the upper mids to lower treble area. Some tracks are obvious while others aren’t. Also, there is some glare at times too. I don’t feel this is a regular issue with the NA20, but for those sensitive to some shout or harshness take note as the NA20 can exhibit some of that. Granted, it hasn’t been such an issue that I feel it detracts from the overall experience of this set. By-and-large the experience (to me) has been very nice and the mids are a huge reason for that. The NA20 has that milky fluidity and creamy style which sounds emotionally gratifying along with enough dynamism to remain exciting, yet all of this is done in a warmly coated canopy of sound. It’s nice folks. 

Lower-Midrange 

Looking at the lower-mids, to my ears stuff like male vocals is downright awesome. Male vocalists sound only slightly recessed, they sound authentic, they sound authoritative, and basically a man’s voice sounds like a man’s voice on the NA20. So much of the time with other sets the lower-mids can sound drab, almost boring, less enthused. With the NA20 there’s this toned-down but identifiable vibrancy which feels more like dynamics and comes across with many different instruments and male voices. I am quite literally listening at this moment to “The Sound of Silence” (cover) by Disturbed and David Draiman‘s voice is everything from softly edgy, feathery, and gentle, to symphonically guttural and completely jarring with his amazing vocal abilities. The NA20 tackles his voice very well. However, it isn’t just his voice, it’s the melody which surrounds his voice which also comes through crystal clear, nicely weighted, totally canorous, orchestral, and tuneful. I could keep going with descriptors, but I think you get the idea, it sounds good. Also, I have so many names of males in my notes which I speak similar words about. However, even a higher pitched male like Nate Ruess of Fun. comes across very clean-cut and vivid as he belts out the track “Carry On”. Essentially, male voices do come across very nicely for a $119 single dynamic driver earphone with a mostly V-shaped tuning. 

Upper-Midrange 

The upper midrange on the other hand has more pep, more vigor, more sprightly energy and the upper mids are a hair more forward in the sound field. However, the upper-mids also can be a bit sharp at times too. I’ve already said this, but I don’t feel this is a huge issue. I’d say the NA20 may sound sharp to someone who is sensitive to it and that’s about it. Females come across a bit more dry, thinner, and they don’t sound quite as authentic as the lower portions. Though I’d never say they sound artificial either. Again, some version of organic which sounds great for an eyes-closed listening session. Man, listening to Sia go to work on the song “I Forgive You” shows you just how well controlled this single DD is and just how musically adept this set is. No doubt there are some singers which hit that somewhat harsh level like Cam in “The Otherside” or Megan Trainor in “Sensitive”. But those are not the norm. More than anything I hear effervescent inflections from female after female leaning very much organic, clean intonations, flowery, and the only good word to describe them is mellifluous. Songs like “Don’t Know Why” by Norah Jones are one of those tracks. Very nice for any set, let alone a $119 single DD. Her vocal notes have a roundness to them, a certain clarity, they sound as though they have this mist of warmth, this delectable salient prominence as Noah’s softly sung lyrics face inward at the listener. Obviously, there are other sets which can provide similar sonics as the NA20, but that doesn’t take away from how nice some females can sound. 

Downsides to the Midrange 

Okay, so there are a lot of “preferential” downsides that I could list here. I’m not talking about my preferences either. I’m talking about you, the consumer, and possible issues that some may have. Trying to get a grasp on who this set fits and who it might not fit. So, to start the NA20 is not going to be that ultra snappy and highly detailed technical beast of a set. It also won’t blow your mind with its midrange resolution. This is a warm, semi-rich tuning and so you have to be okay with some smoothness, less exact, slightly blunted, and a sometimes-masked midrange. It isn’t perfect, but it’s nice for those who can appreciate its sound. At any rate, the midrange does have some spill over from the bass region and so you don’t have those ultra clear and clean midrange notes. Don’t get me wrong, within the warmth and the richness is very nice clarity, however the smooth delivery does sometimes level off the precision of some notes. I’d also add that complicated tracks can sometimes smear the sound field. Similar to any single DD tuned in this way. Another downside I hear is the shout which can at times rear its head. I want to stress that I can listen for hours and not be affected by this at all. However, you also have to remember that I enjoy just about every sound signature out there (with varying degrees of joy) and shout really doesn’t bother me unless it’s too coarse, abrasive, or piercing. 

Supporting Actor 

To be quite honest I find the midrange to be nice. NF Acous did a solid job on this set folks. I’d just stress to anyone looking to purchase that they shouldn’t expect a mid-centric tuning and anyone who is looking to purchase this set should be okay with average technicals (details, separation, transients). As I said before, the good far outweighs the bad and the mids do a very nice job of being a solid supporting actor for this set. 

Treble Region 

The treble area is somewhat relaxed at times and at others it can come across with a nice level of brilliance. It all depends on your music choices. NF Acous made sure to provide plenty of emphasis up top which does help to illuminate some details in the region as well as add some much-needed levity to the mix as a whole. I’d definitely call this a V-shaped treble style with enough vivacity for the highs to feel energized but relaxed enough to sound subtly subdued. I like the level NF Acous added here. They didn’t roll the treble off to appease those who are overly sensitive, and they didn’t boost the treble past comfort to appease those treble heads amongst us. However, I feel that the treble is just past edgy. Certainly, it isn’t mellow, and it isn’t dark. Let’s put it this way, the highs on the NA20 take the listener right to the cusp of sharpness only to cap that energy and the result is actually quite nice. Now, having said that, I’d also say that the NA20’s treble region operates with a smoothness to it. This is not an ultra-precise treble with sculpted notes and all the treble bite or even loads treble punch. There is some of that, but by-and-large the NA20’s highs are smooth and brilliant. 

Examples

Resolution is not the NA20’s calling card in the treble region, but I’d still say it’s above average to my ears. Shoot, half the sets made anymore are very much non-aggressive up top and the NA20 at least slightly pushes the boundaries a bit. The increase in emphasis alone helps in the resolution department. Especially for low-volume listeners. Anyways, the treble has some clean resolution as note definition is nice for a single DD at this cost. I also say that because there’s definitely a certain fine-lined clarity within the treble. Notes do have some nice body too, they aren’t overly thin, or overly dry. The track “Evil Twin” by Lindsey Stirling provides my example as every note is cleanly established, rounded, and they have some density to them in this faster paced song. Each note comes across with a nice edge to it as Lindsey puts in work with her violin play. The timbre is pretty nice as well. I don’t hear anything blatantly artificial, and I don’t hear anything metallic at all. Perhaps there are the faintest touches of sibilance on some tracks, but I really don’t feel it is an issue. It isn’t overdrawn or too tizzy. There are other tracks which show off that organic style treble timbre, like “Bishop School” by Yusef Lateef. It’s another track with loads of different types of treble energy, coming in fairly fast, very multifarious and eclectic. The NA20 handles it pretty good. Obviously not to the taste of treble heads and not to the skill level of some hybrid sets, but nice and very cohesively tuned. 

Extension 

I also find that extension into the highest of highs is not bad at all. The NA20’s treble extension does add some air and some openness to the sound. To add to that, the extension does help widen the psycho-acoustic image of the sound stage to a degree as well. There is the faintest splash up top in more complicated cymbal passages but most of the time the NA20 handles the secondary harmonics of a cymbal strike very well. Violin has that nice edge to it and I find the presence of those instruments sounds fairly bold against the rest of the mix. Again, not to the degree of some other driver types but great for closed-eyed listening. I am definitely impressed at what NF Acous did with this single DD when I consider the tuning as a whole.

Praise Fest? 

I don’t want this section to become a praise fest, and I want you to know what you are getting. I mean, the treble isn’t perfect, that’s for sure. It doesn’t have that hard and defined bite and clean edge like a good BA or Planar and it doesn’t exactly separate instruments quite like some sets. What the treble does well in my eyes is simply complete the tuning. It just sounds good in a melody. It isn’t the type of treble which is going to force your mind’s eye to zero-in on every micro-detail. Remember, this is a musical style tuning folks. NF Acous wasn’t trying to tune some detail beast or analytical monster. They weren’t doing that. In fact, they told us what this set was supposed to be and guess what… They did exactly as they said they were going to do. This set is ALL ABOUT EMOTION. Drawing out the emotion. It’s all about velvet musicality, fluidity, yet with added dynamism and almost this pent-up rhythmicity, even elegance. It isn’t about making sure every faint little detail is heard, or every treble note is contoured with perfect precision. They wanted it to sound good folks. That all said, I don’t think I could leave the treble section without saying that they did a solid job. The treble works, it fits, it cohesively melts into the overall tuning very well and even adds some brisk brilliance too. 

Downsides to the Treble Region 

Of course, there are some issues too. I’ve already spoken of some of them. No doubt the NA20’s treble region is not perfect. You will likely not be seeing any treble heads singing its praises anytime soon. Like I said, NF Acous told us what target they were tuning this set to. This is their “musical series”. So, we should all know at least somewhat what to expect. This is not the most precise, articulate, and pristine treble I’ve ever heard. You don’t have those haptic dynamics that you can feel when the treble punches or in hard and fast dynamic shifts. The NA20 doesn’t have stop-on-a-dime in/out agility within the treble. This is a smooth, ride the wave, ease of listening type of treble. You’ll hear some slight smearing of treble tizz and splashiness from time to time in complicated treble tracks too. So, it’s definitely not a treble-head’s delight. However, I honestly wouldn’t change a thing because the treble region fits the target. It fits the vision. Now, it may not be for you in particular, but I do feel that there are a huge number of hobbyists who will love this style. Also, I said in the beginning of this paragraph… “the NA20’s treble region is not perfect”. I want to rephrase that to “the treble region isn’t perfect for everyone, but it will be to someone”. 

Technicalities 

Soundstage 

The soundstage of the NA20 has good width (above average), nice height too. There’s no lack there at all. The NA20 feels big. It has this really full sound, like… all of my head space. However, the sound is also somewhat intimate, it’s closer to the listener. Not too close either. It’s a “draw-the-listener-in” type of stage. You have those emotionally charged tracks, the warmth, the expressive dynamics, and the closer but also very full stage. On top of that, the NA20 also has a fair amount of depth to the sound field as well. You’ll notice some nice front to back layering going on as well. It certainly isn’t a flat 2D plane of sound. Which is nice to hear. The soundstage is definitely a “pro” of this set. 

Separation  

Looking at the NA20’s ability to create distinctions between instruments and vocalists I have to say that it’s about average. A very solid average. However, depending on the track you may hear a far above average ability to sparse out each instrument separating them all very well. I’d say its biggest issue is in heavily complicated tracks as well as heavy bass jams with a deep and ongoing bassline. You’ll hear some masking at times in those situations. In simpler and less chaotic situations the NA20 usually is able to create very clear distinctions between instruments. So again, it really all depends on the track you’re listening to and to some degree what genres you generally listen to. I’d love to say the NA20 has a master class ability to separate the sound field, but unfortunately those congested tracks don’t usually jive very well with V-shaped and bass heavy single DD’s. However, it isn’t bad at all folks. The good thing is that the NA20 isn’t ever a congested mess. The sound always comes through clean. 

Imaging

This brings us to imaging on the NF Acous NA20. I find imaging to be spot-on precise. Granted, in heavily congested tracks that sound image can blur a hair.  Friends, this is a bass emphasized single DD, the sound is richer than it isn’t. There’s some air and openness, but the NA20 is not some thin and dry set. It’s a smooth sounding iem. It isn’t glass-lined and transparent. So, sometimes in busier tracks the notes converge a bit. You can’t get around that. Again, I am so impressed by this set’s ability to be as good as it is. I say that because the NA20’s ability to render every instrument within the soundstage in a very clean way is fantastic. Also, every one of those instruments has its own spot to operate in. Again, you have good layering front to back and left to right is spot on. In my opinion imaging and layering are very good, even with the semi-rich, warm, and bassy sound. 

Detail Retrieval 

This is another area which seems to be a tale of two sets. You’ll either have amazing detail retrieval in “less” complicated tracks, and then some possible congestion in “more” complicated tracks. Please understand that this is not across the board and there most certainly are tracks that will make a liar out of me. It also depends at least slightly on what source you are using too. Having said all of that, detail retrieval is mostly very nice for a single DD at $119. Especially for a set that wasn’t tuned to prioritize detail retrieval. That’s really saying something of the drivers and acoustic physical tech involved with this set. So, a little nod to the engineers behind the sound, nice work. I’d say detail retrieval is average to above average. Yes, I know “Average” and “Above-Average” are ridiculously subjective judgments. However, I’m also of the opinion that anything average or better is very good for the NA20. 

Is it worth the asking price? 

In my opinion the NF Acous NA20 sits in between a bunch of really solid single dynamic driver earphones. Just under it in cost is the Dunu Kima 2 (Kima 2 Review), the Simgot EA500LM (EA500LM Review). And just over the cost of the NA20 you’ll find absolutely awesome single DD’s like the Fiio FD15 (FD15 Review), and the Hiby Yacht 10 (Yacht 10 Review). However, there are so many more folks. Especially when you get up to the $200 price point. At that price you’ll find some of the best price to performance single DD iems on the market in the Simgot EA1000 (EA1000 Review), the Tanchjim Origin (Origin Review), and sets like the Dunu Falcon Ultra, as well as one of thee best but most unsung $200 single DD’s, the Penon Vortex (I love that set). Again, this is just to name a few. The point is that competition is ridiculous for single DD’s. I’m not even bringing up budget single DD’s either. There’s so many. So, without question the biggest hurdle for the NA20 is the iems it’s positioned around. Having said that, there aren’t any of those sets tuned like the NA20. Not even close. The NA20 is a call back from the old school to a degree and a sound that I didn’t even know I was missing. Also, it’s only $119 folks! Of course it’s worth the asking price. For all that it gives you I think it’s a no brainer. 

The Why… 

Because the build is one of the most functionally complete builds that I’ve used. NF Acous prioritizes comfort over all else. The NA20 is built with some high strength and low weight polycarbonate resin which makes for an extremely lightweight set of earphones. Fantastic for long sessions and nice for stage use too. The fit is subjective, but I don’t see anyone having issues with the ergonomics of this set. Also, the unboxing is really cool. I really didn’t expect that. However, it’ll always come down to the sound and let me tell you; the NF Acous NA20 was meant for pure musical bliss with eyes-closed while you are soaking in your music. Or dancing, whatever you are into…no judgments here. It’s smooth, smooth, and smooth. When I think of the NA20, and I see a wave. But this wave has some good solid energy, some dynamics, some gusto. I love the timbre, and I love that the NA20 fits most genres fairly well. The NA20 has that beefy bass with solid density which can make its way around just about any track fairly well. The midrange is lush (semi-lush) with forward-ish vocals which come across much better than I ever would’ve expected a V-shaped set to sound. Great off-natural timbre. Both technically sound as well as wonderful for its straight up musical nature. The treble is non-fatiguing yet still has some real sparkly brilliance and fantastic extension into the highest of highs. The stage is large, deep, but also so nicely intimate helping that smooth and warm tuning to draw out any emotion from my music. Imaging is pretty much spot-on too. Folks, this is a very high-quality tuning and the NA20 has a sound that the market has been lacking for some time. Yes, it’s worth the $119 to purchase it. No doubt about it. 

Ratings  (0-10)

*Note: all ratings are based upon my subjective judgment. These ratings are garnered against either similarly priced sets or with similar driver implementations or styles with the unique parameters of my choosing. In the case of the NF Acous NA20 ratings below, that would be $100-$150 US single dynamic driver earphones. Please remember that “ratings” don’t tell the whole story. This leaves out nuance and a number of other qualities which make an iem what it is. A “5-6” is roughly average and please take into consideration the “lot” of iems these ratings are gathered against. $100-$150 single DD earphones are not the largest scope of iems. So, It shouldn’t be too surprising to see a few ratings above a “9.0”. My ratings are never the same and each set of ratings tells a different story. Each time you read one of my ratings will be unique to that review. Basically, I create a Rating that makes sense to me.

Ratings Summary:

To sum up the ratings above I first have to remind you all exactly what was being rated here. I was rating the NF Acous NA20 against any $100 to $150 single dynamic driver earphone. Thankfully, I have most of them in my possession to rate against. Of course, I also extended that $100 down a bit to reach some even lesser expensive sets. I figured that most people who are looking for a single DD, are only looking for a single DD. Hence why I didn’t expand this ratings session out against every driver configuration. It made sense to me and hopefully it makes sense to the consumer too. At any rate, a “9.2” is fantastic. Obviously, if I did rate against every driver configuration then these ratings would be a lot different. Also, please don’t make a buying decision on ratings… ever. Ratings are fleeting impressions which last only until the next set comes out and changes everything up. I really feel strongly about that. If you see a ratings board, take it for an actual grain of salt. 

Explain Yourself!! 

I honestly don’t feel there’s anything to explain here. The ratings speak for themselves. A “9.2” overall is a legit score and I think it’s right. The one rating that I feel some people will take issue with is the “Midrange” rating of “9.3”. I could see some folks thinking that is too high, and I wouldn’t argue with them either. I feel that the straight up musicality of this midrange is strong enough to put it there. However, I also had some other midrange killers that I was putting the NA20 up against. So, you may think a “9.3” was high, but really that score is in fourth or fifth place. I suppose the “Musicality” rating of “9.8” may also get me some weird looks. However, as far as sheer musicality goes, the NA20 is the best of the group in my opinion. Beyond those ratings I feel the rest are right on the money. That’s my opinion though. So, grains of salt. Instead of looking at ratings, read and watch full reviews, read consumer comments, and try to get a good understanding of a set before you hit the “Buy Now” button. 

Final Thoughts on the NA20 Before I Finish

It’s not always easy to explain something to a group of consumers who all have different ideals for their music. We all think so drastically different at times. The NA20 was a tough set to explain. It has its fair share of issues. Those “issues” may be deciding factors for some people and here I am speaking about those issues but also praising this set in the same sentences. I suppose it all comes down to preference and what means the most to you. Some folks may not be able to deal with the shout at times. Maybe the sibilance will be too much. However, what makes this set special is how well it replays music as a whole. What makes this set special is how well the bass, the mids, and the treble converge to form this tapestry of sonic goodness. This set wasn’t crafted for its detail retrieval. It wasn’t created to sound reference. The NA20 will never be that set which forces you to pay attention to every minor detail. It isn’t that. The NA20 was created to bring smooth musicality to the masses. NF Acous told us what this set was tuned to be, and they did exactly that. I think NF Acous did a helluva job with this set and I truly hope they receive their flowers for that. I really do. At any rate, I simply wanted to say that I absolutely rec this set for anyone who desires a bassy, warm sounding set with plenty of non-offensive brilliance who simply want to melt into their music. No doubt about it. 

Conclusion 

Thank you! 

To conclude my full review of the NF Acous NA20, I first have to thank the good people of NF Acous, and especially Eileen for providing the NA20 for review. Friends, one of my favorite sets back in the day was the NFAudio NM2+. I’ll never forget how many hours I spent adoring the sound, the design, the build. Also, the NA2+, same thing. I loved those sets. However, it has been years since I actually spent any time with a product from this brand. After the NA20, I want to try them all. But I digress, thank you NF Acous, and thank you Eileen. I also want to thank you, the reader, for taking the time out of your day and clicking the link to get you to this review. I say it in every review. Thank you. There is nothing more meaningful to the people of mobileaudiophile.com than clicks and views. Clicks and views are our currency, and we try to provide content that is geared towards you, that will help you to hopefully make a decision which will end in musical bliss. That’s the hope. Thank you. 

Other Perspectives 

Another thing I say in every review (and mean every word) is to try to compel you to check out other reviews now that you’ve read mine. This hobby is so very diverse. Diverse in the products, diverse in brands, diverse in tunings, and there’s a lot of diversity in the people of this hobby. We are all so very different in so many ways. How often do you see a review praising something only to turn around and check out a review that speaks terribly of the same exact product? It happens constantly. There is no right or correct sound. That doesn’t exist. There are differently tuned products and our individual subjective feelings towards those products. And often… those feelings differ. That’s the hobby. I say that because I really want each of you to click some more links to some different reviews. Read, or watch other thoughts. Get some different perspectives. Hopefully, you will gain enough of an understanding to make a purchase which will be meaningful. With that said, I’m done folks. So, please take good care, stay as safe as possible and always… God Bless!!
