Letshuoer Cadenza 4
Intro
Hello, today I have with me the latest iem to grace the market from the very popular audio brand Letshuoer, named the Letshuoer Cadenza 4. The Cadenza 4 is actually a four-driver hybrid which consists of one dynamic driver and three balanced armature drivers, but more on that later. Folks, I have been a fan of Letshuoer for quite some time and have owned a number of their iems and one thing I feel that I can say with complete conviction is that Letshuoer is only getting better. While other brands rest on their laurels and stop trying to innovate and create, Letshuoer is doing the exact opposite. They use different driver configurations, a unique company to partner with in “HeyGears” and some of the best tuning that we’ve seen over the course of the last three to four years.
Good history with this brand
I’ve reviewed a few of their iems but have owned many more and each one I’ve been extremely happy with. Not that any of you asked. However, I reviewed and gave high marks for the Letshuoer S12 Pro (S12 Pro Review). Truly one of the best planar magnetic earphones that money can buy for under $150. I reviewed one of the better iems under $100 for vocals and simply great timbre in the Letshuoer DZ4 (DZ4 Review), and finally I reviewed the Letshuoer S15 (S15 Review) just last year. The S15 is my favorite planar iem… period. All of these sets mark some of my favorites in their price point. Something about this brand’s ability to tune and craft sets that have a rich and fun timbre without lacking in the technical stuff is flat-out intriguing. Truly they are fantastic at their craft.
Letshuoer
Letshuoer was actually founded as “Shuoer Acoustics” back in 2016 by Jeff Wong & Danny To. From what I can see, they only seek out the best in the field to work on their products and it seems as though they are quite proud of their team. Letshuoer has a long history of bringing some very well beloved iems to market. We’ve seen sets like the Cadenza 12 which has been lauded in the community. There’s also sets like the EJ07, EJ07M, EJ09, which all fall into the high-end price point. Of course, Letshuoer has also done very well in the budget space starting with their Letshuoer Singer, Letshuoer Tape, Letshuoer Tape Pro as well as some of the most loved planar iems you can find. Sets like the Letshuoer S12, S12 Pro, Z12, S15 and more. I also really enjoy the Letshuoer D13 which is also a low-cost example of a fantastic single DD under $100, and finally the Letshuoer DZ4, as I mentioned earlier. Folks, all of these iems are well thought out, well built, well designed and well-tuned to the target sound that Letshuoer was going for. It’s safe to say that Letshuoer has built somewhat of a dynasty, and I’m all for it.
Tough competition
There is a huge swath of iems that sit within the $200 to $300 price point that the Cadenza 4 fights against for your dollar. To be honest, this seems to be the one thing which holds most sets back. My biggest question and concern for the Cadenza 4 is if it can stand next to some of the greats in this revered price point. Well, I suppose that there’s only one way to find out. Let’s take a look at the Cadenza 4 friends…

Packaging / Accessories
Unboxing
I love a good unboxing folks. Always have. Even if it lasts a short moment and is gone. Just a small shot of dopamine, I’ll take it. Thankfully Letshuoer knows how to package their iems in a way which shows them off. Also, they have such a cool way of doing so. First off, the Cadenza 4 comes in an average sized rectangular box; roughly 6” x 4” x 3”. The box has a sleeve which showcases their Logo, a neat design and some specs. If you look at the pics you can see that it’s hard to describe. It’s a neat, clean, and Apple-esque in its presentation. Anyways, slip off the sleeve and you are met with the actual box. Open that box and you’ll see an envelope with some reading material (that I won’t talk about now). Under that you’ll come to the earphones themselves sitting in cardboard covered foam cutouts. Next is the cool part. Just like the unboxing for the S15, the Cadenza 4’s box has a cool little drawer at the bottom. Pull the fabric drawer handle and you open up to the case on the left and the modular connections on the right. Inside the case are the tips and the cable. This is certainly one of the more unique and inventive unboxing experiences. Nice work Letshuoer!
Eartips
Inside the case you’ll find the eartips which are stuck on tabs on this round holder of sorts. The tips provided are of pretty good quality though I can tell you right away that I didn’t use them for my review. The first set (S, M, L) is a white shallow fit silicone eartip with a wide bore set with a flimsy flange. They drop down the low-end a bit too much and really pushes the upper mids/lower treble area for me. Not my favorite. The next set is a narrow bore set (S, M, L) that is able to insert a bit deeper and is semi rigid at the flange. I simply don’t get the seal I need with either of these tips. I actually went with the Letshuoer S15’s blue wide-bore tips in large. They seem to do everything I need them to sonically and fit like a glove. Honestly, if the included tips actually seal for you then I’d say you are good to go, and they are of decent quality.
Carrying Case
The carrying case which comes included in the packaging of the Letshuoer Cadenza 4 is a hard plastic hockey puck shaped case with screw on threads. The plastic has that very cool feeling soft rubber coating over hard plastic. I’m sure some will feel that this material isn’t up to the price, but I completely beg to differ. This material has almost a soft texture to it, and it feels about as nice as plastic can feel. The size is great in that I can put the earphones, cable, tips, and possibly a small dongle dac as well (I haven’t tried to fit a dongle dac) inside and the top simply screws down nice and easy. This is actually almost identical to the carrying case which came with the Letshuoer S15. Perfect for throwing into a bag or even putting in a pocket without any worry whatsoever. Obviously, we’ve seen more elegant cases provided with iems. On the flip, we’ve also seen far worse from iems that were much more expensive. So, take that for what you will. Not a bad case by any stretch.
Cable
One of my favorite aspects of the whole Cadenza 4 package is the cable. It’s a gorgeous white cable, it’s thick, it’s modular as well. Really, a well-designed wire folks. The white is almost glossy, and the braid, or twist, is awesome in appearance. I love a fat cable, it just makes my iems look that much better, and when they color match… now we’re talking. Anyways, the cable is a 2-pin, made using silver plating over high purity monocrystalline copper and 392 strands. Furthermore, the bonus is that this cable is also modular, coming equipped with 3.5, 2.5, & 4.4 right angle modular jacks. I also like that they used stainless steel (I believe) strain reliefs and 2-pin fittings and every other fitting as well. It’s a slick design and a great addition. The modular Jack’s tightly push onto the connector and are very firm and fitted perfectly. I do get the most minimal microphonic sounds when rubbing on my shirt. However, that is almost not worth mentioning because it is so faint. Thankfully I don’t have to purchase an extra cable. So, there’s that.
Build / Design / Internals / Fit
Build Quality
The build will either be something that is a very nice to you, or it will be something that isn’t. Some people have issues with Letshuoer’s use of HeyGears materials. I actually really like HeyGears build quality and feel that it only adds to the Cadenza 4, but I can see why others don’t like it as much. However, I’m speaking to those who do. The build is fantastic with that semi-soft, yet dense plastic formed by way of 3D printing. Inside there are also 3D printed acoustic tubing which are perfectly aligned to the drivers. In fact, everything internally is built in this method, the chassis, the casing for the drivers, the tubes, vents, the whole nine yards. This method ensures precise control over the acoustic cavity everytime. The faceplates are crafted by way of CNC machined aluminum with a cool textured matte finish. Also, the Cadenza 4 is very light which helps for long listening. The nozzles have three holes where the acoustic tubes terminate at which are also medium in length. I think the build is fantastic folks. If you are going to build using plastics… this is the way to do it.
Design
This leads right into the design and aesthetic of the Cadenza 4 which I happen to adore. I love the minimalist, silver on white, clean aesthetic. Clean, clean, clean. You have that matte chalky white finish on the Shells that contrasts lightly against the silver matte finish of the faceplates. It’s tough looking. The faceplates have a small ridge running top to bottom to add some gradient texture with “Letshuoer” printed in parallel with that small ridge. I will say that this look won’t be everyone’s favorite, but I cannot help but be impressed. Iem design is always intriguing to me. I’m fascinated with how these brands try to separate themselves from the sea of sets. The visuals, the build, the graphics, whatever. The point is, I enjoy a brand who isn’t trying to simply win me over with flashy looks. The design is simple, but also sort of bold in that simplicity, and for that I say… “Well done, Letshuoer”.
Internals
Letshuoer decided upon a quad driver setup. A “hybrid” quad driver setup that is. That’s one 10mm beryllium coated dynamic driver for the lows, one Sonion balanced armature driver for the midrange and two Knowles balanced armature drivers for the highs. As you can see the drivers are made by reputable companies whose sole purpose is to craft & create drivers. Now, I don’t know who the maker of the dynamic driver is, but I do know that it is the same or similar to the driver used in one of Letshuoer’s more high-end iems. Also, I’m speculating on what parts of the frequency each driver accounts for. We all know about the word “assume” though… it makes an “ASS” out of “U” & “ME”. So, take that as a grain of salt. Anyways, Letshuoer also added in a four-way electronic crossover as well as the acoustic tubes which both work to cohesively separate areas of the mix.
Fit / Comfort
As far as comfort is concerned, I don’t have an issue whatsoever. Once again, I am reviewing a set that fits me like a glove. The only issue I had was with the included tips and finding a seal. However, the Cadenza 4 is made in such an ergonomically sound way that I would think they’d fit the majority of folks. Also, this set is extremely lite. They are not taxing on my ears and trust me, I’ve had these in my ears for over five hours at one time, many times. Comfort is great. That soft plastic seems to really be nice against the skin with no irritation at all. Beyond that, the isolation is better than most as well. Obviously not to the level of ANC sets but the Cadenza 4 still has very good passive isolation.
Drivability / Synergy
The Letshuoer Cadenza 4 is rated with an impedance of 15 ohms as well as a sensitivity of 102 db’s. This is a set that is not hard to drive to volume. However, just because you are getting them to volume doesn’t mean that you are getting the most out of the sound. The truth is, the Cadenza 4 is certainly a set which will provide an uptick in sound quality with more raw power. Also, the Cadenza 4 does react quite well (depending on how you look at it) to source tonality too. I can say with complete confidence that the Cadenza 4 will actually scale very well with more output. Usually, I’d say it’s about the source tonality and source ability rather than the actual power. Definitely some planars react this way and some other sets as well. There’s no “across the board” standard on it. It’s certainly something that we see. That is, power helping to bring out the most in an iem. However, by-and-large I feel that the actual sonic skill of the source brings on the better sound quality and a little extra clean amping helps to add dynamics at times too. As far as the Cadenza 4 is concerned, I don’t think you need a million watts to get it there. Maybe a good strong dongle dac at the least.
Mobile Listening
When on the go, out and about, in my office, doing chores, I’ll usually use a Bluetooth dac/amp or a dongle dac. Rarely do I bring a dap in these situations. I listed only a handful of devices that I used for testing but in reality, there were many more. Using the IFi Go Blu (CS43131 dac chip) was truly one of the nicest Bluetooth moments with this set. Using the 4.4 balanced output I found these two to pair very well. Also, I love the clean tuning and good power of the Aful SnowyNight and the EPZ TP50. Both devices use a CS43198 dac chip and both sounds very similar. Thankfully the neutralish sound of those two was a good mix with the Cadenza 4. However, I wouldn’t say that it is best to only use neutral sources. To be honest, I was more than happy with any source tonality that I tried. The only device that I tended not to enjoy was the Fiio KA3. Other than that, the Moondrop Dawn 4.4, EPZ TP20 Pro, Shanling UA2, Qudelix 5k, Hidizs S9 Pro Plus etc. all replayed the Cadenza 4 just fine. Still, warmer devices do slightly exaggerate the warmth. For whatever reason it wasn’t an issue though due to the Cadenza 4’s resolving sound and clean replay.
A bit more added power
Listening with some heavier hitters I found gave me the same thoughts. I honestly enjoy my iBasso DX240, Shanling M6 Ultra and my Fiio Q15 dac/amp the same. Perhaps the Q15 was a little more on point and clean, but I feel that the warmer M6 Ultra actually replays beautifully. I like em’ all. Slight variations between them but each device is a bona-fide stud and does great while the Cadenza 4 is attached. Also, I did use medium to high gain on each, though I’m sure if I stuck to medium gain, I would’ve been good to go. Still, between any and all sources that I have used with the Cadenza 4, it is beyond obvious that the Fiio Q15 sounded the best paired with it. Truly a great sound when coupled together.
What should you use?
If I were you, I’d try to pick up a good dongle dac. It doesn’t have to cost two hundred bucks either. There are some truly awesome dongle dacs under $100. Shoot, there are some great devices under $75! Even less. I would think that anyone who is affording the Cadenza 4 probably already has a decent source, but you never know. Everyone has different situations.
Sound Impressions
Oh Cadenza 4, how you have entrapped me in your lushness, your milky vibrance. Okay that sounded really weird, sorry for that. Moving on… The Cadenza 4 is what I would call lush and warmish, almost Harman-esque, U-shape to even W-shape sound. I also hear an excellent balance across the mix with the only outlier frequency division being in a slightly more forward midrange. It comes across smooth and has this lush presence across the mix. The Cadenza 4 has warm undertones but does have some added neutral vibrance as well. The sound is creamy but not thick, smooth and velvet but not murky or veiled. This is a colored sound that sits at the fringes of organic with very pleasant timbre & tonality. I would call the Cadenza a musicality first iem, a mostly relaxed iem, and an easy listening iem that is also pretty fun sounding. It simply replays my music so very well. Multiple genres are a treat on this set.
A testament…
This isn’t a set that is going to unveil every last micro-detail (granted it is good for what it is) or separate instruments with perfect fine-lined accuracy. No sir, this is a set that will either move your feet or make you close your eyes and simply melt away with it. Now, because this set replays in the manner that I described, I can tell you this… it won’t be for everyone. It is slightly polarizing in that way. Still, if you can appreciate all kinds of sound signatures then I cannot imagine you’d listen to this set and not be impressed. Very much in step with Letshuoer’s much less expensive triple DD, the Letshuoer DZ4. Just way more refined in every way. To have this warmly layered euphonic timbre, this casual smoothness which comes across so melodic and still staying true to each note without the rails falling off (covered in veil)… is a testament to Letshuoer’s ability to craft top class sets per their relative price points.
Condensed Sound Between the 20’s
If you’ve ever read any review from me then you know I add this section for those who don’t feel like trudging through another one of my 10,000-word reviews. Also, I do understand. However, I definitely cover more, with more detail past this point.
Anyways, the sub-bass has good extension while not overwhelming the mix. It’s clean and has steely density and rumbles nicely. The mid-bass isn’t the most impactful I’ve ever heard. Slightly soft and mellow in its attack but also doesn’t oversaturate the mix which helps to keep the mids less murky. The midrange is warm, lean-lush, forward and truly great for vocals. Maybe it isn’t the most separated midrange out there (not bad either), but I’d take that any day for this musical sound. Very melodic, mood inducing, and engaging. In truth, I find the midrange to be one of the best I’ve heard in the price point. The treble is safe across the board yet with some touches of brilliance peppered into the mix. Not dark, but warm & energetic, not rolled off but nicely extended. I also hear nice liveliness and energy, but it’s toned down a bit. This is non-offensive through and through. Slightly mellow but not without some upper treble spice. I find the bass and the treble do well to create a nice balance in this warmer setting while the midrange sits out front. It’s all very melodic folks and comes together very well. Really a very nice sounding iem. This is not a drab and boring sound, and I don’t consider it dull either. There is good macro-dynamic energy even in the non-brisk and tempered sound.
Bass Region
The low-end as a whole is certainly elevated and does have a very nice presence against the rest of the mix. However, it does sit a touch behind the midrange. Enough to not oversaturate the other frequencies or create too much of a foggy shroud over the presence of the midrange. Pushed back enough to let the midrange shine while not encroaching very hard on them. I find the bass isn’t attenuated or “less-than”. It’s a full bass region. Really, the extension of the sub-bass is pretty deep, and the mid-bass slam is definitely there. Just not that ultra vibrant, sharp & impactful slam. The low-end is dense in body, but also slightly plush in its attack. With that all said, I want to preface the bass section with one thing; this bass region is definitely acting in a supporting role. Everything is about the midrange on this set. Yes, the bass is good and yes, it’s satisfying, but it seems to take a slight back seat.
Sub-bass
The sub-bass is one which will rise to the occasion at a moment’s notice. I’d say that the greater emphasis in the bass region rests in the sub-bass as well. Now, I don’t find the sub-bass to be very overemphasized or aggressive, but it can certainly thump. It’s still full and formidable in its substance and weight but just not so sonorous that it overtakes any other area of the mix. In my opinion, I feel other areas are actually a bit more forward in the sound field like the mid-mid, upper-mids, lower treble too. Unless of course the track I’m listening to features a heavy amount of that sub-bass rumble. That’s a different story. At any rate, the sub-bass has a less defined attack and carries a softer lined but authoritative rumble. I find that it really works very well with the overall theme of the tuning. Enough to add some good haptic vibrational and tactile feel to my music.
Sub-bass cont…
Listening to a track that is always used for review purposes is “Groove” by Ray Wylie Hubbard. I use this track because I know it so well. If a set has some good sub-bass extension or emphasis, then this track will tell me that. Along with about twenty others that I use. However, with the Cadenza 4 I don’t get that overbearing sub-bass growl as I would with other more emphasized iems. That said, I love the emphasis that I do get as it’s still full bodied, it’s still deep and defined and still very agile. Yet, within that semi-deep but full-bodied sound I actually hear Ray’s deadpanned vocals very well as the sub-bass isn’t masking his voice. “Stereo Colour Cloud” by Sampha is another track where the bass region is the foundation of the track. Again, I hear a good and dense bassline coming across, boosted in quantity and clean enough against the backdrop of the rest of the melody. In this way separation is very good. The sub-bass can dive deep and can do so with a more warmly weighted and lush presentation. Also, this is in no way a disheveled or untidy sub-bass. Like I said, agility is actually very good with a ductile and dexterous ability to maneuver through dynamic shifts. It’s deep, it’s penetrative, but it isn’t overdone.
Mid-bass
The mid-bass on the other hand is less emphasized. Still, it has plenty of meat to it but simply isn’t elevated to the point of heavy slam. Let’s put it this way, bassheads won’t be impressed. However, I still find the slam and boom satisfying enough on some tracks and on others I’d say that the Cadenza 4 lacks a bit in this region. I find the mid-bass to be slightly pillowy or plush. Perhaps a hint fuzzy at times. Not perfectly defined or chiseled sounding to my ears. This doesn’t make it bad either. The tonality and timbre are great, very organic and on top of that… It’s still fun and indulging. Listening to “Billie Jean” by Weezer (Michael Jackson cover), the kick drums are certainly enough to provide some density and good weight. However, the drums weren’t as sharp in their attack as I’d usually like. Still, I go back to the fact that the mid-bass, just like the sub-bass, both play supporting roles. This is a warm U to W-shape iem with forward mids and lush engaging vocals. The bass never oversteps its bounds. Especially the mid-bass. In that respect I absolutely adore what Letshuoer has done. It’s big enough, bold enough, it slams, it rumbles, and it does its job. It simply isn’t that emphasized or ultra detailed & defined mid-bass. Also, it doesn’t have the most bullish quantity I’ve ever heard.
Downsides to the Bass Region
The bass region certainly has issues but if you put those issues into context to the situation of the tuning… you may start to see why the bass helps this set to be pretty special as a whole. First, bassheads won’t want this one. It’s not basshead. Yes, it can boom when called upon, but it does not reach bass Boi levels. No sir. Secondly, this is a bass which isn’t pointed and refined. Texture slightly lacks, maybe it’s a bit pillowy at times. Those things are certainly true. I have to repeat myself though; the bass is playing a supporting role. This is so very evident. The tuning is fantastic on this set. Also, besides adding just a hint more mid-bass emphasis in db’s, I’d say I wouldn’t change a thing.
Midrange
Like I’ve already stated, the entire tuning in my opinion supports this beautiful midrange. The mids are like the rest of the mix but simply tuned forward in the sound field in comparison to the bass and the treble. It is so nice to hear because it is tastefully done. In fact, here’s my round of applause. Okay, apparently it is tough to mimic a round of applause in a review. Notwithstanding… great job Letshuoer. The mids are subtly milky through and through. They have their moments of crispness and precision. Still, for the most part the midrange has lean-lush note weight and is never too congested or too weighted, never veiled and never too blurry. The midrange comes through just left of neutral with some warmth. Closer to a creamy style of vocals with good solidity underlying. Without question the mids are emotionally and engagingly refined. Not refined as in precisely defined, expertly separated, or detailed. I mean refined as in well structured, great timbre, and it’s as transient tight as a smoother midrange note can be while still keeping a smooth demeanor. Also, before I go any further let me just say that the detail retrieval isn’t bad by any means. Certainly not a dry or analytical style and so it won’t bring out every last detail, but still resolving to my ears.
Lower-midrange
The low-mids have a slightly warm type of tonal color with a smooth attack and a more velvet style inflection in general. There is some spill over from the bass region though mostly the bass and mids intersect in a clean way. Not quite as pinpoint or as precise as some sets and not surgically abrupt in its note definition. That’s not to say that the Cadenza 4 can’t be that either. In general, and on most tracks, the lower midrange prefers silky and plush over glass lined and crisp. It’s a heavenly way to listen to my music.
Males in this region have a slightly lean body which I would again describe as lean-lush, or svelte-richness. It’s the 1% milk of the audio world. The mass of a note persists whether the actual body is thick or not. Also, the transient attack through release is actually fairly quick and clean within this slightly warmer environment. Instruments don’t sound as though they have prolonged harmonics or lagging decay. It’s as clean a sound as lean-lush can be while still favoring that velvet style timbre. Actually, the beauty of this region (and the midrange as a whole) is that the timbre has that warm natural hue to it. No odd metallic timbre here. When listening to “Blue Wall” by Noah Guthrie, his voice is so well highlighted and etched out, full but pronounced. Male vocals are very well done here. Or Lewis Capaldi in “Someone You Loved”. The Cadenza 4 takes his hard Scottish cadence and smooths over the rough edges. It gently pushes his voice out front, and it really is nice to hear.
Upper-Midrange
I feel the upper mids are the crown jewel of the midrange and the midrange is the crown jewels of the Cadenza 4. Females simply sound devine to me. Now, the upper mids feature thinner note body but still have that plush style of timbre which softens the macro-dynamic energy and vibrance just a hair. This is not an overly energetic or super lively upper-mid. Having said that, there’s still some good capped-off energy and sprightliness there that never goes out of control. I also enjoy the layer of shimmer that exists for all instruments and vocals in this region. Perhaps ever-so-slightly lacking some edge and snap to percussion and guitar plucks, but it really does make up for it in how well it portrays female voices. Still, there is a slight lack in actual pinpoint precision throughout the mids and this holds true for the upper midrange as well. You aren’t getting a Simgot EA1000 style upper midrange, but instead a luxurious one, dripping in emotion and tuned for musicality. Possibly its greatest selling point, which supersedes any of its shortcomings. It’s the engagement factor! Lean-lush richness in every moment, yet still the Cadenza 4 is able to do so in a very resolute manner.
Lovely females
Females are simply great, sounding forward enough to feel out front and on a pedestal yet that forward sound is never overbearing. It’s tasteful. The upper mids come through with smoother textures, while never sounding sharp or glaring. In fact, the entire upper midrange is this way. Never any shoutiness, sibilance, or undue peaks. Listening to Lady Gaga sing “Always Remember Us This Way” comes across a hint thinner in body but also, she sounds sublime with her scratchy but resounding voice. The Cadenza 4 truly shines a spotlight on her vocals. Also, Kacey Musgraves in “Deeper Well” is an experience when listening with the Cadenza 4 attached to the Fiio Q15. Eh, take any source. Kacey’s vocals are so very gratifying and pleasurable for me. The Cadenza 4 really props up her sweet inflections with absolute ease. Females are lovely with this set.
Instrumentation
Also, instruments like piano are very tuneful and full sounding without coming across blunted. Some strings could use a hint more sharpness and edge dynamics but for the most part they come across organic and very nice sounding. Percussive instruments have enough definition in their leading edge though they may lack some crisp snap for some folks. Stuff like snares won’t have that pointed edge to the initial “pang”, but also, they have enough energy to come across like an exclamation point in my opinion. Cymbals always have good weight afforded to them with great harmonics which trail off into the treble. Never splashy or layered in a glossy sheen. Most instruments are slightly smoothened and have that layer of warmth to them which really fits the overall theme of the tuning. Timing is great and so is cadence and it all comes together admirably. I won’t go too long on instruments as every track can replay them differently. However, generally speaking Instruments come through nicely. Maybe there’s the slightest lack of acute punchiness or crispness here and there, but I don’t feel that it is always the case at all. There is still some reserved energy that comes out when called upon. Just don’t expect some ultra lively replay.
Downsides to the Midrange
The mids biggest issues are lack of perfect separation of instruments and the smooth nature of the timbre which sometimes lacks good energy for proper bite and dynamics. This is a set with a slightly softened macro-dynamic energy. Details are not going to emerge like some more technically inclined iems within the price point either. They are there and I do feel that the Cadenza 4 is probably above average, but it definitely isn’t tuned as a detail king in the midrange. Beyond those things, the mids can sound slightly congested in more congested tracks. This probably goes without saying and is likely the case on most sets, but it should be pointed out. However, I cannot help but love the midrange as a whole. Vocals are wonderful and the Cadenza 4’s musicality is really endearing, and the engagement factor is off the charts for the price point. This set takes casual listening to a new level.
Treble Region
The treble is not one which will brighten the entire mix in luminosity and brilliance. It is not that. I hear a warm treble. Not dark at all, but simply warmer sounding with dashes of brightness and enough lift to add much needed levity to the entire spectrum. However, it is warmer, not exuding vibrance to the point that it’s beaming in effulgent luster or anything. This is a partially relaxed sound, albeit with a highly resolving nature. I hear good separation up top while also hearing good extension. Maybe leaning towards being melodious and subdued to a degree but not lacking energy in relation to the rest of the mix. It fits the overall tuning perfectly. I hear just enough shimmer while coming across only slightly less radiant than I’d like. There’s still a bite to the attack edge of notes and though note outlines come through smoother up top separation of instruments is not an issue for me. Also, I can appreciate the more gradual climb through the pinna gain and the nice transition into the lower treble, as cohesion is really great on the Cadenza 4. This is definitely not for treble heads, but I do feel the treble is well done for what it is. It’s cohesive, it’s not going to kill your ears in fatigue and technicalities are good per the tuning.
Good speed
The treble also has pretty nice speed and agility too, but it all comes through in a less sprightly manner. I can hear the very subtle micro-details and micro-dynamic shifts rather well, even in those more complicated tracks. Again, there are sets which are born and bred to illuminate the treble region in forced resolution and are tuned to maneuver easily through any track you throw at them. I’d say the Cadenza 4 can do that to a degree because it has quality treble which simply isn’t overdone or overcooked. Listening to Billy Strings in his track “Secrets” is awesome on the Cadenza 4. His banjo truly moves at breakneck speeds, and I can easily make out each note. Again, I hear good separation of each instrument and the timbre comes across very naturally to the ear. Yes, it’s a tad relaxed, but not in a mundane way. It’s relaxed in its luminance and brilliance. There’s a difference. That takes nothing away from its abilities to be nimble at all times or when it’s called to do so.
Not bad
Extension into the upper treble was not forgotten either. However, Letshuoer made sure that the Cadenza 4 took on the upper treble in a tasteful manner. Yes, it’s warmer, maybe dark to some folks even. Certainly, it stays true to the tuning as a whole. Obviously, they couldn’t pump up the db’s past 10k and throw everything off like some sets we see. Though there is a peak out there which adds some dimension to the sound, some air and openness that is sorely needed. Also, timbre up top is very well tuned into this region. The example I always give is cymbals because they are the most obvious example to use and one which I listen for all the time. The secondary harmonics of a cymbal strike decay very nicely and aren’t simply a splashy mess of treble tizziness. They have control about them. They sound natural to the ear. Well, as best as I can tell anyways. I feel this goes for most instruments. They sound natural up top. So often we hear sets that are either rolled-off or so endued with brilliance and shine that they come across unnatural. I realize that treble lovers may disagree but not everything is for everyone.
Downsides to the Treble Region
I would first point out once again what I’ve already spent time saying. That is that treble heads or bright treble lovers will not want to spend their hard-earned money on this set. It is warmer and toned down, slightly more relaxed than some sets. Also, the energy needed for a solid bite at note edges isn’t as sharp and a crisp crunch isn’t there at all times either. Other than that, maybe the treble is not the most detailed within the $200 to $300 price point, although they are above average in my opinion so, not really a downside. Just not up to some of the best in the price point. However, I wouldn’t want it to be. I wouldn’t want to do anything to ruin the mellifluous musicality of this set. Don’t touch anything.
Technicalities
Soundstage
The soundstage is actually very nice. With the Cadenza 4 in your ears, you will hear a psycho-acoustic stage that sounds wide for an in-ear. This also goes for height. It’s a big and full stage presence. I feel nothing is overly cramped at all. On top of that, there is good depth for layering. Now, I hear this better with a cleaner source, but I find that layering is actually decent and front to back depth is also good. This is a very nice attribute to have. Almost 3D in its presentation of the stage. Obviously, the track will do a lot to dictate just how expansive the stage is for you and some tracks simply aren’t recorded in a manner to best depict this stage. Still, by-and-large the stage is certainly above average in my opinion. Of course, I haven’t heard every set in the price point, but from my journey through audio I find the soundstage to be good and even a “pro”.
Separation / Imaging
This is where we see some closing of the space within the sound field. Separation isn’t perfect. It isn’t bad either. It all checks out though. You have a richer sound with slightly lusher layers and less midrange air separation. Again, not something that takes away from my musical enjoyment, but something to point out. I labeled separation a “con” at the beginning of this review and I did so because there is some slight congestion at times. It’s a softly edged sound, plush, warmer than neutral and sometimes elements of a stage are gently squeezed a hair. Oddly enough, Imaging is fantastic with very nice placement of those elements. Left to right and front to back feature well laid out depictions of an imaginary stage. This helps in layering of sounds within the sound field. Perhaps, those sounds aren’t as defined as some would like but there are still well done and in keeping with the overall tuning.
Detail Retrieval
Here is another area where I run into some slight issues. Well, they aren’t issues to me, but I could see that some people will likely wish that the Cadenza 4 had better detail retrieval for the price. Regardless, I still feel that the detail retrieval is actually quite good for how the Cadenza 4 was tuned and probably average to above average against the field of iems in its price point. The only real caveat is in hyper congested music or very complicated tracks as well as heavy bass jams. In those instances, the Cadenza 4 really doesn’t have the openness, air, transient swiftness or crystalline definition to skirt around more complicated and congested music. Again… I wouldn’t want it to. Still, all things considered… average to above average depending on the track.
Comparisons
Note: These comparisons will not be a duel to the death. My approach is not to crown one set the winner over the other. I simply compare sets to hopefully explain the sound of the set I’m reviewing a bit better. Also, I use very general terms with very broad strokes. I won’t go I to great detail as I do try to keep my reviews under a certain word count.
Hisenior Mega5P ($239)
The 1st comparison involves one of Hisenior‘s earlier releases, the Hisenior Mega5P. The Mega5P is a five driver Hybrid iem consisting of one 10mm dynamic driver as well as four Balanced armature drivers. Folks, the 5P is a special iem which made waves in its genesis. The sound and naturally neutral tonality as well as the balance across the mix is very endearing. Without question one of the best iems you can buy within the price point if you crave that clean mannered balance.
Differences
Starting with the build, the Mega5p is an all resin-built set with a solid chassis and is very ergonomically gifted. Though the Cadenza 4 is probably built to be a bit more durable and at least for me it is just as comfortable. As far as looks go, the Mega5p has that gorgeous black and white swirling pattern that is simply awesome to look at while the Cadenza 4 is more minimalist and reserved in its look and appearance. I like them both. Without blinking an eye, I’d say that the Cadenza 4 has much better accessories with its awesome modular cable, and better unboxing experience.
Sound Differences
Between the two, the Mega5p is definitely the cleaner sounding set but they both have a wonderful balance across the mix. The Cadenza 4 has a much richer note weight and delivery to the 5P’s leaner note weight and more resolving and transparent sound. I find that both sets have about equal bass emphasis between the two. The 5P’s bass is a slight bit more forward in the mix but I feel the Cadenza 4’s bass is actually a bit more agile. The midrange of the Cadenza 4 is much richer and fuller bodied in comparison to the 5P’s midrange. I hear a more lush, creamy sounding timbre on the Cadenza 4, to the 5P’s more transparent and resolving sound. Definitely the 5P has better air, openness and separation in its midrange. That said, the Cadenza 4 is much more musical & engaging to my ears. The treble region is relaxed on both iems, but the 5P is once again the cleaner sounding set, while the Cadenza 4 has the more lush and musical sound. Extension is better on the Cadenza 4 with slightly better bite to treble notes.
Technicalities
Detail Retrieval goes to the Mega5p almost across the board. It is simply tuned in a way to draw out the subtleties a bit easier than the Cadenza 4. Separation of Instruments and voices suffers the same fate for the Cadenza 4 as the 5P has a more defined note edge across the mix. Both sets have good transients that come and go pretty swiftly. I do think it’s easier to hear on the less rich sounding 5P though. Soundstage goes to the Cadenza 4 in all directions. I hear better width and depth with slightly more of a holographic sound. Imaging comes through about equal on both sets. They both do a very good job in this area.
Further thoughts on this comparison
As you can see, these two sets trade blows quite well. You may have also noticed that the two are very different from each other which makes for a classic preference battle. Meaning, your preferences will clearly align with one of the two. It should be obvious which one you think you’d enjoy most. As for me, I honestly enjoy almost all sound signatures and can truly appreciate them both as well as enjoy them both. I think that I am leaning towards the Cadenza 4 though because there aren’t a ton of iems that sound like it. The musicality is simply greater on this set. It is much more melodious and has that weighted and rich timbre that is simply spellbinding to me. I hear many sets like the 5P. So many sets are tuned similarly. Granted I take nothing away from it at all. There are many days that I reach for it when I have a chance to simply max n’ relax. However, the Cadenza 4 has something that the 5P simply doesn’t and that’s raw musicality. I love them both, but I totally understand if you disagree.
Penon Fan 2 ($279)
The Penon Fan 2 is one of those sets that you either love or you don’t. It’s even more polarizing than the Cadenza 4 is, in my opinion. Anything that leans heavy either way of neutral is going to be pretty polarizing. More on that in a bit. So, the Penon Fan 2 is actually a four-driver hybrid iem with two dynamic drivers and two balanced armature drivers. All of the drivers are of great quality. Now, I never got around to reviewing this set, but I can assure you that it is a bona-fide stud. One of those sets that lean so heavy in one direction that brain burn all of the sudden becomes something that is a must. Truly a contender for the style of tuning that the Fan 2 has, but it won’t please everyone.
Differences
First, the Fan 2 is molded wholly out of a very nice resin material while of course the Cadenza 4 has that nice HeyGears build. Again, I still feel the Cadenza 4 is made with better materials, just the feel them both in my hand tells me that. Still, both well made, both are dope looking. I do prefer the look of the Cadenza 4 but that may also be a prisoner of the moment type thing. As far as unboxing experiences go, the Penon Fan 2 has the better set of accessories. Except the cable… definitely the Cadenza 4 has a much better cable. Everything else goes to the Fan 2. Much better tips, much better case. Of course, the Fan 2 is also pricier. The Cadenza 4’s original MSRP is $249 (on sale for $229 now) while the Fan 2’s MSRP is around $279. Of course, the Fan 2 is also on sale constantly. I suggest getting on their (Penon) email list as they promote their sales to those folks who are subscribed. Always good sales. I got the Fan 2 for $150. As far as aesthetic differences I do feel the Cadenza 4 has the upper hand, but the Fan 2 is right there with it. Both worthy of their price tags.
Sound Differences
To start, I thought that the Cadenza 4 was lush, warm and weighted. The Fan 2 is 100% lush! It is so far to the warm/dark side of the aisle that it will directly cut off half the listening population on that alone. However, if you can respect the tuning for what it is than you’ll see how special this iem is. Anyway, the Fan 2 is warmer, darker, and with thicker note weight. The Cadenza 4 is leaner in its approach, it’s cleaner, more balanced and less like molasses. The Fan 2 is a milkshake against the 1% milk of the Cadenza 4. Naturally the Cadenza 4 comes across cleaner and with more vibrant macro-dynamic energy. The Fan 2 however, has that dark sound, but a very highly resolved darkness to it. It is a unicorn of an iem. To be that dark and still come across as W-shape is a different approach that not many brands dare to try, well done Penon. However, the Cadenza 4 has more of a balanced sound that to me is special.
Between the 20’s
The Fan 2 has a more bulbous, thick, full and all-encompassing mid-bass region. The Cadenza 4 is much more lissome, ductile, agile and impactful. Having said that, the Cadenza 4 also has better sub-bass extension, deeper in that region too. The Fan 2 has a quick attack but a slow decay, atmospheric to the umpteenth degree. Whereas the Cadenza 4 hits n’ gets with better control. The Cadenza 4 simply doesn’t cloud the rest of the mix with as much murkiness, while the Fan 2 does have a veil of warmth that permeates the entire tuning. Veiled, but in a very charming way. The Fan 2 has beautifully rendered warm and cozy vocals with a forward midrange that is very thickly weighted. Now, the Cadenza 4 also has good density of midrange notes, but they are also leaner, more sprightly, vibrant and better resolved. I do feel that the rich tonal presentation of the Fan 2 is great, but the clear winner in vocal playback goes to the Cadenza 4, for me. The balance is better on the Cadenza 4, while the Fan 2 is tilted way to the left. The bass of the Fan 2 encroaches in a very tactful way into the midrange creating that nice milky and rich sound while the Cadenza 4 is a bit more tasteful for most people. The treble region of the Cadenza 4 is brighter (if you can call it that), more detailed, faster, more bite, more energy, and better extension by a long shot. While the Fan 2 has this vivid and yet warm dynamic treble that is so nice if you can wrap your brain around it.
Technicalities
Technically speaking the Cadenza 4 has better detail retrieval almost across the board. The Fan 2 specializes in “macro-details” whereas the Cadenza 4 is able to illuminate much more of the “micro-details” from my music. Imaging is special on both iems. Both can reproduce a good stage with good placement of Instruments and voices. Separation is better on the Cadenza 4, and I also find that the transient attack and decay is a bit more lithesome, malleable, and simply springier on the Cadenza 4 as well. With a bit more air, notes are better defined. When listening for soundstage differences I feel the Fan 2 has this intimate, average width, completely musical stage that is so engaging with very good depth of field. Layering is great even with the slightly clouded separation of those layers. The Cadenza 4 does have a wider, taller and more immersive sounding stage, it’s fuller and more all-encompassing and nearly as deep. Though depth is a tough thing to try to quantify, I simply hear slightly better front to back depth on the Fan 2. I think most technicalities go to the Cadenza 4, and it stands to reason. However, technicalities are neither set’s forte. Neither iem is a detail king, neither is dry and analytical in its approach and both have that rich and cozy lushness to their sound.
Further thoughts on this comparison
Folks, I don’t know how to adequately say this but both sets are phenomenal. In truth, I love them both. How could I not love the Fan 2’s lush and vivid fullness and warmly weighted musicality. I love it. So easily I can get lost in how it portrays my music. However, I have been taken away by the Cadenza 4’s lean richness and beautiful midrange quality. I do think that the better iem for me is the Cadenza 4. At times. There are moments when the Fan 2 hits that urge within me. Moments that I want only what it can provide. However, I do think that the more talented and all around better iem is the less expensive Cadenza 4. I usually never say something like that, but I have to be realistic. Not as many people will fall in love with the Fan 2 as I and a few others have. Both are great for what they are, and I am blessed to have them both in my collection.
Is it worth the asking price?
The question posed in the header is one that I feel I’ve answered many times already inside my review. Folks, I would pay the $229 or $249 any day of the week for the Cadenza 4 without a thought! To have what the Cadenza 4 provides to my listening experience is priceless to me. It is fast becoming one of my favorite iems within the $200 to $300 price bracket. However, I have to be real. Not everyone will share my love. When you have sets like the Tanchjim Origin (Origin Review), Simgot EA1000, Rose Technics QT9 Mk3 (QT9 MK3 Review), OG Mangird Tea, Aful Performer 5, Kiwi Ears Orchestra Lite (Orchestra Lite Review), Penon Fan 2, Penon Vortex, Seeaudio Bravery, Dunu Falcon Ultra, BQEYZ Wind, BQEYZ Winter, Kinera Hodur (Hodur Review), ISN Audio NEO 5, it’s a tough road for any set, and that’s only to name a few. There are many more iems that are legitimate studs within $200 to $300. Also, not everyone will yearn for what the Cadenza 4 offers tuning wise. So, I can only speak for myself when answering this question in this particular price bracket. For me, without question the Cadenza 4 is worth the price to own it.
The Why…
Because the HeyGears build is so well constructed, with such a uniform, clean and durable feel. Also, because the Cadenza 4 is 100% comfort and ergonomics. The Cadenza 4 is partially worth the price because of how well the design language is. Such a beautiful design. Letshuoer didn’t need to add any flashiness because the actual charm of this iem is in its simplicity, and there’s something refreshing about that. Fully bold in appearance while at the same time it’s fully elegant. The accessories are some of the best you’ll receive within the price point, hands down. This cable is truly a special one and you’ll know that when it is in your hands. With all those nice words that give proper respect to a well-designed and well-crafted set… the true worth of every iem is in its sound, of course. Folks, Letshuoer obviously used very good drivers and they expertly tuned this set to a very particular sound style which is fastly becoming a Letshuoer brand “house sound”. I don’t know if labeling it that is in agreeance with Letshuoer, but it sure looks like it from the outside looking in.
Cont…
The bass is a very well-done supporting actor which is tailored to prop up the midrange and does so with the perfect amount of depth, visceral slam and it does fortify the low end of the spectrum. Next, the treble has that never offensive but perfectly fitting emphasis which is another supporting role that suits this tuning to the tee. A few db’s added or taken away would change the overall dynamic and so bravo to Letshuoer for the vision that they had when going into this venture. The treble is just brilliant enough but warm in its approach, detailed enough and extended very well without any sibilance, splashiness, piercing peaks or treble glare. Nevertheless, despite how nice each end of the spectrum is, it’s all about the mids. The midrange is flat-out and hands-down one of the best I’ve heard in the price point. No bones about it folks, this midrange is delightful. The vocal reproduction of both male and female voices is exquisite. I don’t say this half-heartedly, friends. I say this with complete and utter conviction. The soundstage is above average in width, deep and with good layering which helps to provide better than adequate imaging. I know that not everyone will share in my enthusiasm, and that’s okay. But man is the Cadenza 4 a well done iem! Letshuoer! Here’s me patting you on the back! Yes, the Cadenza 4 is worth the asking price.
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 Letshuoer Cadenza 4 ratings below, that would be $200-$300 iems in any driver configuration. 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. $200-$300 US is a pretty vast scope of iems that is extremely competitive, and so seeing a Rating above a “9.0” better mean something very special. 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.
Aesthetic
–Build Quality: 8.7 Built very well, HeyGears builds are great.
–Look: 9.5 Clean, fresh, simple, elegant.
–Fit/Comfort: 9.8 Fit and comfort is great for me.
–Accessories: 9.5 Very well accessorized.
–Overall: 9.4🔥🔥
Sound Rating
–Timbre: 9.4 Top class timbre.
–Bass: 8.5 Extension, great supporting role.
–Midrange: 9.8 Great presence in the mids.
–Treble: 7.8 Relaxed but great tonality.
–Technicalities: 8.4 Soundstage & imaging are great.
–Musicality: 9.7 Musical thru & thru.
–Overall: 9.0🔥🔥🔥
Ratings Summary:
Have I ever explained to you how little I enjoy Rating anything? Folks, please hear me, ratings are no good. I do it because I’m asked to. They tell nothing of nuance and never give the full picture. It’s a cheap way to explain anything. In each rating category, I could have multiple sub-categories. These are bare bones ratings, so give the proper weight to the importance of them. That’s very little. Grains of salt my friends. That said, I do have to rate the Cadenza 4. However, let’s not get things twisted, like most sets, the Cadenza 4 cannot be broken down into categories. This is a set which should only be rated and reviewed as a whole. This is something I say often in my reviews, and it couldn’t be truer than for the Cadenza 4. When each Rating is individually broken down and rated it simply looks worse than one grade as a whole. Even when I tallied the ratings and got a “9.0” total sound score it still is less than what I would give this set. It’s a “9.5” at least in my eyes. Probably more like a “9.8” against the field of sets that I’ve heard. However, you have to enjoy the tuning for this to be true to you as well. Not everyone will agree with that. Coincidentally, that is exactly what makes this hobby the best hobby on earth. I’m convinced of that.
Explain Yourself!!!
Okay, so there are more than a few ratings which may garner some anger and DM’s (yes this happens). Some of you are crazy about this stuff and actually get mad, which is weird, so calm down and hear me out. Time to be adults and act like actual men… and women. I would say that the bass category could go a few points less for some folks. I’m sure they won’t find it as enthralling as I do. It isn’t the most defined, not the most glass-lined and clean, doesn’t have the best transient swiftness. So how did I give it an “8.5”? Because of what it is for the overall tuning. Yes, I could use a hint more lift in the mid-bass, but the extension is great, and the density is good too. It’s resolute enough for an 8.5, it does have adequate rumble and plenty of slam for most any genre. To be honest, I looked this over for a while and with a total of 10 iems in front of me I established that “for me” the low-end carries an “8.5”, give or take. Timbre may be a problem for some folks too. You do have to enjoy the warmer, richer and less vibrant timbre to agree with me that it is a “9.4”. Basically, you have to actually like the tuning and so these ratings could go either way. Also, ratings are personal to the reviewer so again, please take this ridiculous section as a grain of salt… please!
Conclusion
To conclude my full written review of the Letshuoer Cadenza 4, I want to first thank the awesome people of Letshuoer for providing the Cadenza 4 in exchange for a feature at Mobileaudiophile.com and a full review. Letshuoer has never once asked me to skew my words, talk well of their products, pre-read my review, and never tried to bribe me or lead me in any direction. Kudos to Letshuoer, they have my respect. Instead, they simply let the chips fall where they may. They believe in their product and that in and of itself is a testament to Letshuoer. So, thank you very much!
