KZ ZAT ($78)
Intro
Hello, the earphones that I’m reviewing today are KZ‘s latest Hybrid in a very long line of hybrid iems, the KZ ZAT. The ZAT came to me when I least expected and I was completely caught off guard by this one. The ZAT is a 1DD 8BA hybrid with a very masculine and confident look to it. I do want to thank KZ and Tyvan Lam for providing the KZ ZAT in exchange for a full written review as well as a feature at Mobileaudiophile.com.
I have been utterly impressed by KZ of late. Truly this company has steamrolled through every price point creating iems that rival and compete well against any in their respective price segments. I’ve reviewed many (KZ iems) over the course of the last few years and if I’m being totally honest…I haven’t reviewed a set that I don’t think is worth the asking price. From the KZ Krila (Krila Review), KZ ZVX (ZVX Review), KZ D-Fi (D-Fi Review), CCA Duo (Duo Review), KZ EDXS (EDXS Review), KZ PR2 (PR2 Review), KZ AS16 Pro (AS16 Pro Review), KZ AS24 (AS24 Review), KZ Linglong (Linglong Review) KZ PR1 Hifi (PR1 Review), CCA CRA+ (CRA+ Review) among many others. Folks, all of these sets are very well done for the price being offered to own them. In fact, the trend is that KZ makes incremental improvements with each new set.
They aren’t going anywhere
KZ/CCA has been an absolute fixture in the Audio community for years and whether you love them or not… They aren’t going anywhere. This is a company who flies in the face of “audiophiles” constantly making earphones that re-invent standards and raise the entire industry as far as price to performance. Like it or not it’s KZ who drives the competition in the budget space. I would venture to say that they are the majority owner of the real reason that under $100 iems have gotten so darn good the last few years. Brands have to perform to keep up. As it should be. Honestly, it’s the consumer who wins in the end. Like em’ or not. Yes, they are rather aggressive in their promotional material but if that’s the worst we have to deal with to get great affordable iems… So be it! That all said… The KZ ZAT everyone…

Packaging / Accessories
Unboxing
The unboxing of the $80 KZ ZAT is a bit lackluster. Okay, it is a lot lackluster. Really there isn’t much to say here as you get the usual KZ box. Open the box and you’ll see the sweet looking ZAT earphones. Under the top layer you will see the rest of the accessories. That is the cable as well as the eartips. Nothing special to report here friends.
Eartips
Inside you’ll receive three sets of KZ Starlines along with a pair of foam tips. I actually love the fact that KZ is still providing Starline tips, and I will most surely use them within my collection. However, I found the KBear 07 tips were the best pairing for me. I’m sure many other tips will do the trick but for me it was all about fitment and getting a good seal. This set is the exact shape and footprint of the AS24. Sound wise I feel the Starlines are perfectly fine but I just could not get the right side to seal well. If I didn’t move at all then the sound was great with the Starlines.
Cable
The included cable is the same KZ cable that comes with every KZ earphone. Whether the set costs $10 or $100 you are getting the KZ cable. It is actually perfectly fine and serves its purpose but really needs to be better than this. This is one area that KZ seems to not have their ears on the pulse of the hobby. Cables matter and this cable is just… meh. It’s the same QDC style 3.5 single ended opaque white silver-plated copper cable with the flat design. I swapped cables first thing and began using a 16-core Fedai SPC balanced cable for my balanced sources. For anyone that is going to use the included cable; honestly it isn’t bad, it does the trick and works as intended. Also, it isn’t an ugly cable. still, I really want to see a KZ earphone packaged with a very nice cable though, who knows maybe one day. Let’s take it to the next level KZ!!
I should also add that KZ does give the option for a cable with a mic. I have used KZ’s mic’d up cables in the past and believe it or not the mic doesn’t sound bad at all. Also, you can control your music through the button on the microphone housing.
Build / Design / Internals / Fit
Build Quality
The KZ ZAT is flat out built like a stud! KZ decided upon a very robust alloy faceplate with a diamond plate design carved into it. The faceplate is screwed into place using three screws. The housing and entire acoustic structure internally which makes up the shell was achieved through the process of 3D printing. Very intricately done. On the back side of the Shells is the four dip-switches. The nozzles are a hair longer than most iems but they feel solid, and they are capped off with a white screen mesh. The build quality is there. This is something that KZ doesn’t skimp on. So, when I’m wishing for a better cable, I can see where that extra money is going to. Really the ZAT is built like a house. To add to that, the ZAT has some weight to them but not overly hefty. They won’t fall out of your ears anyways. You can always count on KZ providing a good build.
Design
This is where I feel that KZ really nailed this set. The ZAT looks very masculine and bold in design. The diamond plate faceplate looks flat out tough with each indentation of the diamond plate pattern painted deep blue which adds a dope contrast to the shiny silver. I love that you can see straight through the slightly marooned-out shells and get a peek at what’s inside. Truly a very well-designed set. Of course, this shell shape and mold has been used before as I just did a review on the KZ AS24 which has the identical housing shape. I think the ZAT is a cool looking set. It isn’t overtly glamorous like the AS24 but it’s simple and bold and I like it.
Continuing the classic design
KZ Promotional
Through multiple intricate processes such as polishing and finishing, it showcases a unique metallic texture and offers a smoother and more refined tactile experience.
High-precision 3D Printed Resin Housing
We utilize high-precision resin 3D printing technology to construct the three independent acoustic channels of KZ ZAT, achieving intricate internal structures that are challenging to realize with conventional molding processes.
Dip-Switches
KZ is still on the dip-switches kick. I know many roll their eyes over the latest switch craze. However, KZ really seemed to dial them in over the course of the last few sets. They make them simple to understand and use. With four switches there are a number of settings to use though many of those settings will run-together. Basically, there’s about four switch setting configurations that makes the most sense. “Up” means “On”. “Down” means “Off” for the purpose of this review. I won’t go heavy into detail of what each setting does. It just takes too long and honestly; you can figure them all out and play with them when you pick this set up. I’ll do a general run-down of what they do though.
Basically, the first two switches seem to affect the bass region while the second two switches seem to affect the upper-mids to highs. KZ does provide a pamphlet with the settings and what they do. Still, If I’m going by past KZ dip-switch settings then the first two switches likely will increase the bass region (as a whole) by 1-2 dB’s each switch. The upper mids are the same. Both of the next two switches likely increase the upper-midrange to lower treble by 1-2 dB’s each switch. So, you can imagine how you could change up the sound by flipping switches. I cannot say this is the case for sure (how many dBs added) but from what my ears tell me I do think this is about right. I can say for sure that the treble seems not too much affected other than how the treble reacts to other frequencies getting boosts.
UUUU
In this setting you get a mostly V-shaped to U-shaped sound with a boosted bass region, boosted upper midrange, and the treble already has a boost as it is. This gives more emphasis to the upper mids which can add some slight glare on the right tracks. I don’t mind this setting, but it isn’t my favorite. There’s definitely some peekiness and shout on a couple of my tracks but those are few and far in between. Not bad. Perhaps a bit bright and too energetic in the upper midrange. I can tell you for sure that this isn’t the most natural configuration.
DDDD
I actually really enjoy this setting. It is the most balanced of all and closest to something like the KZ AS24 that I heard. You get a mild bass presence but a nicely airy sound. I like it. Is it my favorite? No, it isn’t. However, I got used to it easily. Definitely the most balanced of all with a clean and detailed upper frequency and a moderately punchy low-end.
UUDD
This is my preferred way of listening to the ZAT. I just think that adding anything to those upper-mids presents a problem on some tracks. Not all, but some. I think the rise of the bass does well to offset the emphasis up top. The sound is more organic and there is some much-needed warmth as well. You get some good thump down low as well as some above moderate rumble. Nothing Bass-Boi caliber but emphasized, nonetheless.
DDUU
Just don’t do this. It is bright, forced almost. I could see some folks liking this, but the sound is thinner and a bit more artificial sounding. The spectrum is more one sided to the “right” and at least for me it becomes very sharp, too crisp and grating in the upper portions. Especially on songs prone to glare.
UUUD
This is another pretty nice combination. There is the full boom of bass emphasis as well as a nice spike in the upper-mids. For whatever reason as long as you don’t increase both the #3 & #4 switches then you are okay. Maybe? It’s just a bit airier and more energetic in the UUUD configuration. Bass is nice in this setting as well and it’s a pretty well-rounded way to go. Perhaps it’s a bit too energetic in the upper-mid/pinna gain area, but it isn’t bad at all. I did use this setting a bit.
Built-in Professional Electronic Filter Supports Customized Sound Tuning
KZ Promotional
To meet the diverse listening preferences of users, KZ ZAT incorporates professional tuners internally, supporting custom adjustments across the entire frequency spectrum, including low, mid, and high frequencies.
Difference Between Traditional Damping Net and Electronic Filter for Tuning
Traditional damping nets adjust the sound by changing the density of the damping net inside the sound tube’s diameter. You need to replace different damping nets to achieve different sounds, which cannot provide precise control over tuning. In contrast, an Electronic filter is a frequency-selective device that filters waves, allowing for precise tuning of specific frequency ranges.
Internals
Inside of the ZAT you have a number of Drivers folks. Nine to be exact. That’s 1DD and 8BA’s! That’s a lot of drivers to tune! KZ chose to use an 8mm Dynamic Driver of unknown material (at least I can’t find it anywhere). The mid-frequency array was done using #29689 BA’s, the mid-high frequency is taken care of with multiple #30019 BA’s, and the ultra-highs are being played back through multiple #31736 BA’s. Internally you’ll see the tubing connecting to the nozzle. KZ used a precise three-way crossover within the multi-channel acoustic cavity. I do feel that KZ is upgrading their drivers as well as learning to tune them very well.
Fit
The fit is quite literally the same as the KZ AS24. So, if that set fit your ears then you are in business. I for whatever reason am blessed with ears that seem to get a good fit no matter the earphone. I don’t know why. That being said, I have zero idea if these will fit your ears or not. They fit me like a glove. Oh, and by the way, isolation is actually very good in this set. The ZAT are moderately heavy, not super light but they also fit deep into the ear, so it doesn’t feel like any weight at all.
Drivability
The KZ ZAT is a very easy set to drive. Rated at an 11–18-ohm impedance and a sensitivity of 111+3dbs makes them very sensitive. Really, I have zero issues driving this set off of most of my gear. Using something like the iPad sixth gen I was able to bring the ZAT to volume pretty well. Granted it isn’t the most audibly gifted unit so, it does help to have a better source. However, power requirements aren’t very dire. Listening with the IFi Go Blu, the Moondrop Dawn 4.4, or the Hidizs S9 Pro was a breeze as the ZAT seemed to marry well with all three of them. I would say that any source with a bit more warmth would pair better but that is not necessary.
Listening with the iBasso DX240 was very nice but I found the timbre to be a bit unnaturally tainted. Not bad by any stretch but I have the Shanling M6 Ultra which is warmer, more velvet and richer in sound so between the two I definitely liked the M6 Ultra better. As far as power goes, I would say that you do get some boost of separation and macro-dynamic fullness with more power. Don’t leave out the ability of the source and synergy to boost your listening experience. I certainly found that the ZAT was very much capable of scaling to both the extra power (to a degree) as well as the quality of the source.
In the end
At the end of the day, just get a decently powerful source with a nice sound and you’ll be good. I’m not going to go into how each source sounded paired with the ZAT because we don’t all have the same gear and it’ll mean nothing to many of you. I do like slightly warm to warm/neutral sources a bit better, but that’s me. You may feel differently.
Sound Impressions
Note: I want to preface this section with a few things. First, I burned this set in for about 30 – 40 hours. I did notice a slight tightening of the bass region and some of the artificial sound in the upper areas of the mix died off. I listen only to flac or better files stored on my devices and use UAPP (primarily) as my music app along with Hiby Player (at times) and Poweramp.
In a nutshell, I hear a very full sound and a very exact & coherent sound from the ZAT. There’s a seemless transition from the DD to the BA’s and the sound is nicely refined for the price. There’s actually a lot of similarities between the ZAT and with KZ’s other flagship, the KZ AS24. The similarities are mostly in the actual tone & timbre and macro-dynamic energy. They are very similar in some ways and different in others. One way the ZAT is somewhat similar is the very musical sound that it has. Both sets arent dull at all. Both have plenty of vibrance and both are speckless in their resolve. I also think it’s very important to note that I don’t think this is a set to listen at extremely loud levels. It can get a hint too bright. Especially in any setting other than “UUDD”. Granted, I listen pretty loud so…take it with a grain of salt.
Get it dialed in!
The ZAT is a very clean sounding slight V-shape to U-shaped set. I wouldn’t be surprised to hear folks say that it’s even W-shaped depending on switch orientation. The sound can be nearly organic to slightly artificial as well, depending on the switch settings. Truly, a lot depends on what sound signature you like to listen to. It can go from warm/neutral to almost bright, and everything in between. However, one thing I can say for sure is that the KZ ZAT sounds fantastic when you get them dialed in to suit your wants and needs sonically.
Quick look between the 20’s
I must add that my impressions are in the UUDD or UUUD setting configuration. They don’t differ all that much. Just a hint of brighter pap and smack to certain instruments with the extra switch enabled. That extra upper mid zest does add some zing to the sound. However, for the most part they come across very similar. Anyways, the bass is nicely emphasized. The ZAT has some thump. It’s a quicker bass but it also has a nice decay. Certainly not like the BA Bass of the AS24. It holds its release of each note a hint longer. The midrange is pretty forward but not enough to call it mid-centric. Vocals are a hint thin but very nice sounding for the price. Very musical. The treble area has some zing and some bite with good extension. Even with the last two switches down. Detail retrieval up top is very easy to discern and altogether I feel that the treble does a good job of adding some vibrance to the mix. The stage size is above average and there is some depth and imaging are fantastic.
If the quick sound impressions are all that you read just know that the ZAT is a very well-rounded set. Possibly it may be a bit too bright for some. Maybe some will want more low-end. I could see some folks wanting more warmth for better note body. I could see a lot of subjective gripes, but the truth is, the KZ ZAT is a well-tuned iem that will please anyone who enjoys this type of signature. KZ keeps upping their game and they prove it set after set. Obviously, there are always issues but the KZ ZAT will definitely compete at the $70 to $100 price point.
Bass Region
The low-end is either just past neutral or moderately boosted. This is in no way a bass-boi/basshead iem. Not even close. If anything, I want more in the low end. Still, it has more thump and authentic oomph than something like the KZ AS24. I love that set too! Love that BA Bass! But you cannot replicate the sound of DD bass like you have on the ZAT with a BA. The ZAT has some slam to it. There’s enough elevation to carry most genres pretty darn well. It can thump folks. Just not in an ultra-colored and bass dominant way. This is a mature bass region with a high-quality bass for the price. It’s quick enough to move through fast bass passages of music and it’s slow enough and atmospheric enough to let the hip hop bass drop linger a tad. It’s not bad.
Sub-Bass
I find the sub-bass has plenty of guttural growl to bring upon the “feeling” of the low-end. Listening to “Groove” by Ray Wylie Hubbard it is clear that there is enough elevation to authoritatively rumble with some tactility. “Paradigm” by The Head and Heart is another deep bassline that has all the feels. The ZAT has the adequate extension into the lowest if lows to carry some nice vibrational resonances. Certainly, this is a tight sub-bass that isn’t even close to one-noted.
Mid-bass
The mid-bass also has enough slam and boom to easily cover a track like “2040” by Lil Baby and Lil Durk. It’s satisfying folks. Also, the deep and forceful kick drums in “Billie Jean” by Weezer (MJ cover). The ZAT actually has that hollow boom and a tacky note edge. It sounds very nice. Bass guitar has just enough body and fullness to replay it well on most tracks, bass vocalists do have enough weight to their voices to sound sonorous and commanding.
Downsides to the Bass Region
I could certainly see many of my friends in the hobby wanting more of a bass presence. A warmer and thicker presence. A heavier boom. I could also see some folks thinking that this is too elevated. It’s somewhere between the two extremes. Honestly, I think the bass is great for what it is and what it was tuned to be. It’s a bass that can handle quick bass sets and the bass has pretty nice macro-details. The note edge is not soft and note body is not hollow or weak. To be honest, the ZAT bass is a better version of the AS24. In my humble opinion.
Midrange
As a whole
The midrange comes across neither recessed nor too far forward. Perhaps more forward than most. That said, there is a nice rise in this region which enables a cleaner and more vibrant midrange. I found that when both bass switches are up, you’ll hear some very rewarding bleed into the midrange. It’s never bothersome or muddy, but instead it’s an additive to the midrange. Not a detriment. There is some slight added warmth to male vocals and instruments. Separation between instruments is very well done as the midrange does have decent control with a tight transient attack & release. The midrange comes across with a tinge of knife-edge timbre, a little crisper at the note outlines. However, very nice. There is some smoothness but teetering to the crisp side… so be aware of that. The midrange is also lean-lush in the overall body of notes for both vocals and instruments. Especially as you move up the midrange. However, there is still a ton of musicality and a sense of mellifluous inflection in both vocals & instruments too. It’s clean and detailed and more exact than it is milky and smooth.
Lower-midrange
Starting off with male vocals within the lower midrange I find that there is an uplifted sense to this region. There’s an intensity that is very vibrant. I would say it’s not the most organic. Not bad at all either. I would definitely like a hint more warmth here but for the most part the sound is absolutely crystal clear. Truly. In the track “Bless the Broken Road” by Home Free it is ridiculous how resolute the sound is. I can pick apart every last finite and subtle thing. The details are great. The vocals in this track have enough richness to not come across “artificial” while they toe-the-line between sharp and crisp. The overall body to notes has some girth for male voices which I find very well done. Honestly, with the “UUDD” settings I find males to sound endearing yet at the same time they are exact in transient agility. It’s a very well done tuning for the price, but also… it’s a particular type tuning.
Upper-Midrange
Female vocals have plenty of shimmer and are very airy. Maybe a hint too pronounced, especially listening to sharper tracks and the brighter dip-switch settings. Definitely this is not a set for anyone who is allergic to a more vivacious sound. Females sound very much uplifted. “Stampede” by Jess Williamson sounds very clean. Not analytical but clean. Not sterile either because there is still some level of softness within the zesty brio of her voice. There is most certainly some lushness in the melody of her accentuation and intonation within her vocals which bolsters the clean note edge. These BA’s within are very exact, yet still allow some semblance of velvet silkiness in a female voice when a track calls for it. Kelly Clarkson sounds very nice on the ZAT. She is forward and has great presence in the track “Down To You“. She sounds smooth and buttery with plenty of shimmery energy. Honestly females sound great to me.
Instruments
Most instruments come across very well separated against any song’s backdrop listening with the ZAT. Strings can be a hint less full in sound yet with great harmonics and they are very well detailed in general. Percussion is very stentorian, with a good punch and charged pang, pap, or tisk. Violin has that edgy feel with plenty of body. Piano generally is resounding and tuneful enough, and again… very well detailed. Secondary harmonics may be lacking a bit from the tight transient decay of the BA drivers but that really isn’t something most people would ever notice. Most instruments are nicely vibrant without coming across too thin, or brittle, or glassy sounding.
Downsides to the Midrange
If I were to pick apart the midrange, I would first say that it lacks the fullness that more warmth could provide. While not predominantly thin, I definitely don’t consider the midrange rich and lush. Compared to the AS24 I would say the ZAT is a bit crisper sounding, yet also the ZAT probably has the higher resolving capability. There is also a hint of extra coloration in the upper midrange that does come across as “Not” entirely natural or organic. This isn’t enough to bother me because the midrange has way too much that it does well. Also, it’s only slightly non-organic. Very detailed, not sibilant, not recessed, and not flat… not even in thee slightest bit. Macro-dynamic exuberance is very high with this set and the sound is very fine-tuned and precise. However, I can tell you right now that this is not for everyone.
Treble Region
The treble is accentuated and emphasized with very nice extension bringing upon a lot of good info past 10k. This is a highly resolving treble with loads of details. The treble region of the ZAT also has some decent treble bite. Possibly, the treble may lack a hint of note body, but I don’t see this as a real issue at this price. Also again, with the right switch settings the sound can be a hair sharp and even slightly piercing at times for some people. This is an uplifted treble that has very good control. Honestly, I really enjoy the “UUDD” switch settings as the low-end emphasis is just enough to offset the sound up top which renders the treble region lustrous and shimmery but not as peaky or ear-gouging. There is a ton of zest and life up top with very nice energy which just adds to my music.
Speedy Treble
Listening to Billy Strings “Secrets” it’s almost effortless for the ZAT to navigate through Billy’s rapid fire string play. Or the track “Bishop School” by Yusef Lateef. In this song the treble activity is in abundance and the ZAT handles it like a champ. Each and every instrument is well separated and distinct. I don’t want to oversell this set as it is an $80 iem but for what it is, it’s good. Honestly, KZ tuned this set to be very dexterous and catch any little modulation or intonation to any sound, be it an instrument or a vocal set. The treble is speedy, it’s highlighted, it’s very well separated, and you don’t get that mishmash of treble sheen that can happen on really complicated tracks. For the most part.
Downsides to the Treble Region
The biggest drawback to the treble is that it can get peaky. I can handle a very bright set and be happy with it. Somehow, I’ve developed that over the course of reviews. Trying to understand and find joy in every sound signature. However, this treble is simply vibrant and sometimes a bit too piercing. I could see a person becoming fatigued listening to the ZAT for long periods. Especially at higher volumes.
Technicalities
Soundstage
The soundstage is just about average. Maybe a bit wider than usual for an $80 set of earphones. However, it is a nice stage. There’s plenty of height and depth to give a realistic and nicely portrayed mental image. I can say for sure that nothing feels congested at all and nothing feels cramped.
Separation / Imaging
Separation of elements within an imaginary stage are very well done. There is exactness in the note definition on the KZ ZAT. It’s clean throughout. Transient response is on the leaner and quicker side. Also, you don’t have any one frequency taking over the mix to blur the field of sound. Honestly, I think that separation of instruments and voices is most certainly a “pro”. The same goes for imaging. The KZ ZAT really does nail down these two attributes very well. I hear nothing out of place or skewed from left to right. Layering is there as well which is a product of the good depth to the sound. So left to right, front to back will yield good results. Nicely done KZ.
Details
This is where the ZAT excels. The detail retrieval is very good. Of course, this comes at the expense of some added brightness but as far as detail retrieval is concerned the ZAT will go down as one of the better sets in the price point, and probably above. Details are illuminated very easily on this set.
Comparisons
Note: to keep the word count down I am only going to make very general and quick observations. It is imperative that I keep my reviews to a decent length. I will not go too in depth and won’t dig very deep but instead I’ll make a blanket quick comparison. Also, I don’t make comparisons to pose one set as better than the other. I compared to show the difference so that some folks can better understand the set I’m reviewing.
Truthear Hexa ($80)
The Truthear Hexa (Hexa Review HERE) was another of those iems that set ablaze the under $100 price point with a sound that was very much missing in the price segment. The Hexa is a 1DD / 3BA Hybrid iem which is tuned very well, built nicely, and has a sleek and understated look. It’s just a nicely done iem across the board. Now, does it fit everyone’s preferences… most definitely it does not. You couldn’t find two people in a row agree about that set. It seemed it was either the best thing ever or the worst. Very polarizing. I for one love the Hexa and find its replay quite nice. Let’s check out the Hexa next to the all new KZ ZAT.
Differences
First major difference that you’ll notice is the size difference. The ZAT has a lot more to fit into its acoustic structure. The Hexa is much smaller, thinner and not as bulky. The look of both sets is pretty cool though I am liking the ZAT look a bit more at the moment. Like most sets that are put against a KZ set… the Hexa is accessorized much better. Better cable, tips, and you also get a soft leather pouch with the Hexa. I find the Hexa is closer to neutral in tonality whereas the ZAT is more like a warm/neutral sound with a splash of brightness.
Sound Differences
The Hexa sub-bass has a deeper and more extended rumble, but the ZAT has the plumper slam and boom of the two. Both are tight bass regions, but the ZAT has the firmer and more emphasized mid-bass. The midrange sounds more forward on the ZAT though both sets present good midrange efforts for the price. I really enjoy both iems in this regard. The ZAT has a slightly weightier midrange with better warmth for males. The Hexa is a bit smoother yet also more dull to my ears while the ZAT has a bit more energy and vibrance. This extends into female vocals where the ZAT has some shimmer and vivacity that the Hexa doesn’t have. The treble region of both sets has an energetic rise but it’s the ZAT that has better bite and a bit more punch up top. I find the Hexa has better extension though. Both sets offer very good detail retrieval in the treble region with the ZAT just edging the Hexa out for being slightly more resolving.
The soundstage if the ZAT is wider and has better depth while the Hexa stands about average in this regard for the price. Separation is very well displayed on both iems as well as imaging. However, the area that surprised me was in the detail retrieval. I actually think the ZAT outperforms the Hexa on many of my test tracks.
In the end
When all is said and done this is another battle that will be won in the preference of the listener. Both are awesome iems in my opinion but the difference between the two is large enough to warrant a preference battle. The ZAT simply has more energy and liveliness whereas the Hexa is a bit more balanced across the board. The ZAT is certainly the more fun sounding set of the two yet still retrieves very nice details in my music. For different reasons I enjoy both of these iems. I like the Hexa because it’s easy going, non-fatiguing and clean with great technical chops. The ZAT on the other hand is easy to like because it has that sprightly energy and the very resolving sound that doesn’t skimp on the bass region as much.
KZ AS24 ($109)
The KZ AS24 (AS24 Review HERE) was one of the better surprises of the last year for me. I truly regard it as one of the best sets in its price point. It is a 12 BA per side earphone that has a wonderful balance and great tonality. It’s shaped identical to the ZAT that I’m reviewing today actually. I realize I said that the ZAT is likened to the AS24 with DD bass, but I slightly have changed my tune. Both sets are phenomenal in many regards but there are some differences.
Differences
Shaped the same, same size, the ZAT however is much less extravagant in its look as the AS24 is much more on the Bougie and glamorous side of things. Both sets have nearly identical packaging & accessories, and both are close in price. I find the ZAT to be a bit brighter and not as smooth as the AS24 but there are more similarities than not.
Sound Differences
Beginning with the bass. The ZAT has a much more textured and deep bass. As much as I love the AS24’s good BA Bass, it doesn’t compare to the ZAT’s Dynamic Driver low-end. The ZAT has better oomph, slam and is more atmospheric. The midrange of the ZAT is more forward by a slight degree. I also think that the ZAT has more of a crisp edge to its midrange whereas the AS24 is smoother. Females are brighter on the ZAT, and males have a slightly richer note weight. The treble of both sets has about the same extension up top past 10k, but I find the ZAT has a hair more of an emphasis. The AS24 has better body but less punch and bite than the ZAT. The ZAT also has the more detailed replay in my opinion. I find the ZAT to have a slightly larger stage and with better depth and both sets have fantastic imaging and separation.
In the end
I honestly don’t know which set I like more because I like them both. The smoother sound of the AS24 is wonderful, but I also enjoy the low-end of the ZAT a bit more. Both are phenomenal for their respective price points; both represent great sets for any collection with plenty of clean musicality. Honestly, these two are very similar in sound with very little that separates them. It took a very long time of listening to spot the differences. The easiest to spot is obviously the bass but note definition of the ZAT is definitely crisper and more defined.
Aful Performer 5 ($219)
The Aful Performer 5 (P5) (Mahir’s P5 Review Here) quite literally took the hobby by storm about a year ago with reviewer after reviewer lobbying to get a shot at this set. The hype train was alive my friends. The P5 is a five driver Hybrid iem with a very nice timbre and tonality and a nice balance across the mix. Built beautiful with an all-resin design it is a true player at the $200 price point. The P5 certainly had those who adored it as well as some serious detractors. However, let me assure anyone reading, there’s nothing wrong with the P5. It simply doesn’t fit everyone’s perfect preferences. Like any iem. That doesn’t make it bad.
Differences
As far as what separates the KZ ZAT and the Aful Performer 5. Other than a huge price difference of roughly $130 give or take. The P5 is much more expensive and the P5 is a 100% all-resin earphone that is really built wonderfully. Granted, so is the ZAT. The P5 obviously has a much better cable, eartips, basically all of the unboxing trumps the ZAT in every way. Which I’m assuming we all expected. However, the main differences begin to really make their mark in the sound department.
Sound Differences
The P5 comes across more neutral, safer, a bit flatter and less dynamic past the bass than the ZAT. Beginning with the bass, I find the P5 has a bit more in the tank with a heftier slam. However, that slam is also more pillowy and fluffier than the ZAT. The ZAT has more punch down low with less in quantity but a bit more in texture. The midrange of the ZAT is more forward and energetic while the P5 has a smoother midrange. Males on the P5 have more note girth and weight but also females come across duller. I find detail retrieval in the midrange goes to the ZAT. The treble region of the ZAT has better resolution, detail retrieval and flat-out pep. The ZAT simply has more emphasis and the crisper treble. This doesn’t inherently make it better either so don’t read it that way. In fact, the P5 is less fatiguing but also less crisp and has less bite. Basically, the P5 has the safe treble while the ZAT took some risks. Details come about easier on the ZAT and both sets offer about the same stage size.
In the end
At the end of the day, this was not a battle at all but instead a comparison to help explain the ZAT. The ZAT is simply more energetic across the mix while the P5 is toned down, easy, smoother and maybe a bit safe in comparison. The ZAT has that quick attack, sharp release macro-dynamic energy that sounds fantastic for what it is, and I could absolutely see folks choosing this much less expensive KZ hybrid over the >$200 Performer 5. In the same breath, those who want an easier listening sound, with a bit more low-end muscle, and a smoother note body will likely find a home with the very well-tuned albeit much more expensive Performer 5.
Is it worth the asking price?
Here’s the $80 question, is it worth the price that KZ is asking you to pay for the KZ ZAT. Friends, if the tuning seems like it fits you then I’d say this is a no brainer. It is an extremely well built iem that looks dope with working dip-switches and it sounds very good for the price. Ya know, there was a Facebook post where I said this may be KZ’s best set yet. I don’t know if I agree with my own words, but I will say this, the ZAT is a very well-conceived and well-crafted iem. Truly if the sound signature fits what you enjoy then I’d say the ZAT competes at a much higher price. That said, not everyone will enjoy the ZAT as much as the next guy. I do think this is one of those sets that you either really love, or you don’t. However, for me, I think the ZAT is absolutely and positively worth the $80.
The Why…
Like I said, it’s built in a very durable fashion with a tough look that you won’t find on any other iem. That diamond plate pattern with the blue is freaking great. Really a nicely designed iem. The ZAT performs at a very high level. I’m telling you that the ZAT is a highly resolving iem that sounds very clean across the board. From the bass through the treble, you have a clean replay. It’s also very energetic with a “quality” Bass region, a detailed and pleasant midrange and a vibrant and technically savvy treble. The stage is a big size, the imaging is absolutely spot on. I mean this set performs Technicalities like a champ. Really a nice set.
Of course, not everyone is going to want this brighter hue to their music. Not everyone is going to want a transient quick and snappy sound. So many of my friends desire a warmer and more rich sound which the ZAT simply cannot provide. Many of my friends want a bassier sound rather than this moderately emphasized bass on the ZAT. I really think that you will go one of two ways when listening to this set. However, I’m a reviewer and it’s my job to figure it out. Also, I don’t figure it out to please me. I put myself in other people’s shoes and look at how KZ did… with what they were trying to accomplish. I can look past my own likes and dislikes and look at something for what it is. Also, I honestly enjoy all signatures. That said, the KZ ZAT is a set that does very well at the price of $80.
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 KZ ZAT ratings below, that would be $50-$90 hybrid iems. Please remember that “ratings” don’t tell the whole story. This leaves out nuance and a number of other qualities which make an earphone what it is. A “5” is exactly average and please take into consideration the “lot” of iems these ratings are gathered against, this is important. $50-$90 hybrid models is a fairly small scope of iems and so seeing a “9.0” for instance, is pretty understandable. My ratings are never the same, never cut n’ dry, and each set of ratings tells a different story. Each time you read one of my ratings it will be unique to that review. Basically, I create a Rating that makes sense to me.
Aesthetic
-Build Quality: 9.0 The KZ ZAT is very well built.
-Look: 9.5 This set looks BALLER to me!
-Accessories: 4.0 We all know KZ doesn’t add a bunch of accessories
–Overall: 7.2
Sound Rating
-Timbre: 8.8 The timbre and tonality are nice, not perfect but pleasant timbre.
-Bass: 9.3 Quality over quantity here
-Midrange: 9.3 The mids are fantastic on this set in my opinion
-Treble: 9.4 Great treble timbre, detail & emphasis for the price
-Technicalities: 9.8 The ZAT thrives in the technical aspect of its sound
–Overall: 9.3🔥🔥🔥
Ratings Summary:
Looking at the ratings they basically speak for themselves here. Honestly there aren’t as many hybrid iems as you may think, and I can only judge against those which I own or have spent enough time with to have a qualified personal opinion about. So, I made my ratings in the $50 to $90 range because I’m thinking about the person who is looking to make a purchase. After all, these are the people I write for. Basically, I am thinking about the person who wants to try out a hybrid set and $90 is the absolute highest they can go. This is what made sense to me at the time, who knows maybe I could’ve done it in a smarter way. Anyways, I don’t think these ratings need much explanation. The ZAT is a very good set. Of course, it has its issues but those are “subjective” issues and not necessarily problems with the tuning itself. Ya the accessories are sub-par but if the money goes to making a better earphone… so be it.
Conclusion
To conclude my full written review of the KZ ZAT I want to again thank Tyvan Lam and KZ for once again providing me the ZAT in exchange for a feature and review. Guys and gals, KZ is really doing some great things. I also love that they aren’t simply going with safe type tunings but instead are spicing things up. They are adding different types of sound signatures and guess what, they are doing very well with the target they are going for. Not every iem maker can say this. Many go the safe “Harman” tuning, and they sell some units and move onto the next variation of a Harman tuning. KZ is doing some of those, but they are also switching up their game. The ZAT is a perfect example of this. I had a good time reviewing this set and I’m happy to give it a “Rec” from me. If that means anything to you.
Other opinions
With those thoughts in mind, I want to implore you all to check out other reviews of the KZ ZAT. Get other opinions. I promise you will hear differing thoughts about this set. I also promise that not everyone will give them glowing marks. Simply put, we are all different. We don’t all have the same gear, we don’t have the same hearing abilities, likes and dislikes, music libraries and we all haven’t been down the same audio journey. Also, I don’t profess to be the “Be All-End All” of reviewers. It is a wise move folks. I thank you for reading, take care and stay as safe as possible… God Bless friends!
