INNOVATIVE ELECTROSTATIC TECHNOLOGY DELIVERING SUPERIOR PERFORMANCE
KZ ZEX has been engineered from the ground up to deliver superior performance in terms of sound reproduction. The way it is achieved is by employing cutting edge low voltage electrostatic technology in the ZEX. Designed to house a speaker utilising electret driver technology, this delivers consistent and stable sound. Utilising this technology, the ZEX can deliver high-density sound and clarity while reducing distortion levels to a minimum. Benefit from the high-density sounds and hi-res audio performance of the electrostatic KZ ZEX with better vocal resonance, louder and clearer sounds.
ELECTROSTATIC + DYNAMIC DRIVER HYBRID CONFIGURATION FOR PRISTINE AUDIO QUALITY
The KZ ZEX features a unique configuration and combination of driver units, encasing one 6.8mm electrostatic driver and one 10mm dual magnetic dynamic driver that delivers professional-grade sound. The low-voltage electrostatic driver handles the reproduction of high frequencies and ultra-high frequencies, while the dual magnetic dynamic driver is responsible for the mid-frequency and the low frequency. The magnetic force of the dynamic driver added is higher than a standard dynamic driver, this allows for balanced sound distribution. The electrostatic driver ensures much more stable transmission and delivers outstanding reproduction. The combination of the electrostatic and dynamic driver allows the ZEX to accurately reproduce sounds from 20Hz to 40kHz, allowing you to enjoy your music with lifelike clarity.
EXPERIENCE LOW DISTORTION AND STABLE PERFORMANCE IN A EASY TO DRIVE EARPHONE
Comparing the electrostatic driver in the KZ ZEX with a balanced armature driver, the low-voltage electrostatic driver, namely electrets, offers lower distortion and is easier to drive. The performance of low-voltage electrostatic technology, quality and consistency are much more stable than dynamic & balanced armature. The biggest challenge for audio equipment is to provide an accurate sound image with lower THD (harmonic distortion). Electrostatic tweeters can solve the long-standing problem of THD in hybrid driver earphones because they can output sound with lower distortion than balanced armature drivers that offer similar functionality and the KZ ZEX achieves just that. The low voltage electrostatic technology makes it easy to drive the earphone with just 25 Ohms of impedance, allowing it to perform with even a cellphone.
ERGONOMIC DESIGN FUSED WITH QUALITY CRAFTSMANSHIP FOR A SNUG FIT
The KZ ZEX earphones feature high-quality materials and expert level craftsmanship. The materials used to design the housing are of high quality making it durable and sturdy. The body is made of cast zinc alloy and imported resin for a seamless design and showcases complex craftsmanship giving it a futuristic look with special optical effects. Premium quality material is utilised to design the casing of the ZEX, allowing for a snug fit, effectively isolating external noise. The cavity is designed to fit the ear canal perfectly and has been designed ergonomically for a comfortable and stable wearing experience. The overall design reflects the extraordinary quality and feels like a premium product.
HIGH-QUALITY DETACHABLE SILVER-PLATED CABLE WITH 2PIN CONNECTOR
The cable included with the KZ ZEX is of high quality and delivers a distortion-free audio signal. A flat silver-plated cable comes bundled with the ZEX, and this cable enhances audio performance and reduces the loss of signal during transmission. This cable has lower impedance and features a sturdy design making it durable and offering a longer usage life. These cables feature a 2Pin connector on one end and a 3.5mm connector on the other, allowing for easy connectivity with various devices and even allowing for upgradability. The connector plugs are gold platted reducing distortion and allowing for cleaner audio transmission.
FAST BURN-IN TIME AND HD CONDENSER MIC WITH QUICK CONTROL FUNCTIONS
The newly developed KZ ZEX features a low-voltage electrostatic driver which is engineered in a manner that just listening to the earphone for 5 minutes is enough to stimulate the potential of the unit. This is truly unheard of and only a little current is needed to show strong performance potential. The included cable with the KZ ZEX features a high-quality microphone for receiving calls and communication. This microphone is a condenser mic capable of transmitting high definition audio. There are quick-access functions assigned to the button in the microphone housing and it allows for receiving calls, rejecting calls, playing/pausing music and changing the songs played. This is truly useful as you don’t need to access your devices to execute these used functions.

I believe this is an important question.
There are two broad ways to decide if an earphone/headphone/dac/Amp etc are good.
The first is by musicality and it's reproduction of your SPECIFIC library. How does it make you feel? How do the songs you've heard a hundred times come alive with this new piece of gear?
The second way is to measure SINAD values, harmonic distortion, adherence to the Harman curve (if that is your priortity) and the measurement of dynamic range. If it measures better, it is better, end of story.
Although I have been unable to measure the earphones in accordance with method 2. I have heard my library through these for a total of 6 days now.
As per my library, exceptionally produced hip hop and pop Such as Tupac, Dre, Tribe Called Quest and similar artists is reproduced with tremendous authenticity while picking up on all the Easter egg details the producers placed in the music.
However, badly mastered music is incredibly visible through these. Additionally, sample repetition can get annoying because you are hearing every single one so clearly. For example, pop hits from Sean Paul, David Guetta and the entire house ecosystem can get boring fast. The opposite is true for complex layers productions from knife party, skrillex and tool. These earphones will bring out every layer of the music and present it to you like a delicious trifle.
EST is picking up on all the micro details that DD misses and BA over emphasizes. Fit is average. Tips are trash. Wire is fine.
A quality DAC is kind of required to get the maximum out of these. I am using the TC44B by DDhifi because of its industry leading distortion and SINAD values. Truly an incredible combo. I feel like I am in sitting in a studio.
Worth it for the price. If you are comparing this to the CaCC16. This is better as it does not have a metallic tinge. If you are comparing this to the KZ DQ6, the DQ6 performs better for mainstream genres because of its 3DD. But the ZEX tonal reproduction and echo reproduction blows it out of the water. If you plan on listening to a diverse set of music, ZEX is better. If you just want to listen to pop, rock and hip hop, DQ6 is better. If you want to listen to jazz, blues and orchestral music the ZEX seems to be better for my library.
Thank you so much for this detailed review, this definitely is gonna help our customers to make a better purchase decision. Cheers & keep the music playing!
distortion levels are significantly lower than other similarly priced iems, ig it's the EST drivers doing their magic, highs are crispy. Mainly v-shaped sound but sometimes flat. You can hear the bass but you don't feel it. I personally don't find bass-boosted headphones enjoyable, so these are great for me.
Comfort is good, with the right kind of tips you can wear these for hours.
I'm not a big fan of L-shaped connectors, they make use with phones a bit uneasy but not a big deal.
Decent mic, good for calls and zoom meetings.
Overall great product.
Update : upgrading from 4 to 5 stars...now am loving these more than my blon 03 .. because of awesome vocal and balanced lows and highs
This review is based on upgraded Kz 8 core cable and spinfit cp100 tips with shanling Q1 , actually this sound fantastic with shanling Q1 very wide and full
Request to HPZ..please add 4 options in your rating..like next to OK it should be Good and then Great, ( dnt want to mention average nor Awesome :).,
Design and comfort
Value for Money
• Bang on
Again too many positive reviews tempted me to buy this
After 30 hrs burning, now I feel like .ok the reviews are right :)
Blon 03 competitor??? Can say YES and No too :)
Can't match blon's vocal ..but overall sound is definitely good
Lows are tight not bloated
Mids are clean..don't feel like recessed
Highs - before burning I feel like what is this kind?! Very artificial not satisfied., But after burning it's now good..hope it will get much better
Many said it highs are much better than pre KZ's , am not having much KZ this is my 2nd after Edx pro that too bought for the price :) and am really got surprised by its price to performance ratio., So i thought ZEX will equal MOONDROP ARIA sound in 2k range 😊.,don't know how ARIA sounds , but ZEX sounds good
This iem world is a kind of mystery always... person to person opinion differs we can't trust all reviews., You have to check the reviewers taste will suits you or not
Pros : easy to drive, your phone with power amp is enough
Good fit and the cable are also ok for the price you pay , definitely the cables are better than blon's (never seen such a worst iem cable)
Cons : treble could have been better , hope it will get better
But for this price definitely it's worth your money
My setup : OnePlus 7, shanling UA2 with power amp., Spinfit c145 eartips and fiio FD1s (image)
I suggest you to jus switch off EQ completely and turn on TONE AND LIMIT
In TONE - set the BASS at 60% and treble at 50., I feel this setup is great for most of iems...Hope my words gave some clarity
Happy listening :)
I have been using the earphones with my Realme 3 pro(music player - Poweramp Pro(Configured with AAudio output), Music listened are in lossless flac format in both 16bit and 24bit)for 3 days now but it's been on my ears for more than 12hrs with in this span, I haven't used an IEM before so my comparisons would be to the Sony MDR XB55AP which is a bass focused one even then I like the bass on ZEX better it's more of a rich bass it's not as powerfull as the Sony's at the low end but ZEX has much richer bass in the mids. The treble is not even a comparison between these two ZEX definitely has better treble, the mids are almost similar other than in the case of additional clarity that ZEX provides. The Vocals are bit recessed compared to the bass and treble. The soundstage is much better than XB55AP the instrument seperation is phenomenal for me since I haven't heard anything better(Sony MDR EX150AP, [****], Sennheiser CX180 Street 2, Sennheiser CX 275s are other earphones I have listened to so just take it in that context). This thing sounds so good for me I don't wanna stop listening to music. Now to the clear negatives, I have seen reviews complaining on KZ's sharp treble and most reviews said this one doesn't have that but that's just in case of music! But there are rare cases where the treble hurts my ears while listening to music but the obvious problem is when it comes to watching other kindoff content, ZEX comes in a budget area and if you're buying it you are probably gonna use it for everything and while watching a video(to be specific tech news by TechLinked produced by LINUS MEDIA GROUP on YouTube) I had a situation where the host screamed in excitement and it was like he actually screamed into my ears, I'm not sure whether thats a good thing! That's it when it comes to audio it has rich bass both at Low and Mid end, Treble and clarity is good as is the soundstage but the Mids and vocals are bit recessed well that's what V shaped signature means! And to the other things I have some big ears so the Ear hook type cable prevents the ZEX from a firm fit. It doesn't mean it just falls of but I can't even think about headbangs 😂 adding to the injury are the eartips(The worst part about the KZ ZEX) in the box which actually worsens the fit I tried my Sony's ear-tips with it, which actually gave me a better fit but since the stem is narrower most times I take out the earphones the tips stays in my ears. The Mic quality is good. The cable is better than any of the Earphones I listed. Over all it's a good package for the price on what I have seen.
Delighted you are loving it & thanks for the review!
Total value for money product, best iem till date from KZ till now.
