KZ ZEX Earphone Review: Dynamic and EST Hybrid At A Budget

Posted by Gagan Jajoria

KZ Acoustics, short form for Knowledge Zenith Acoustics has released some excellent sets of earphones in the international market. They offer supreme value for money with budget-friendly prices. TBH, It's very easy to get confused with the wide pleothra of earphones that KZ offers for the international market. Recently, KZ has released several different earphones most of which have been at the center of discussions in the audiophile communities worldwide. Today I am gonna share my impressions of one of their latest pair, the KZ ZEX. If you are an active member in the audio communities, you must be familiar with the ZEX just because of all the hype created around the pair mostly because of its driver combination. Instead of a classic DD and BA combination like most other earphones in its price segment, ZEX offers a combination of a low voltage electrostatic and a dual magnetic dynamic driver. In my experience, ZEX is the cheapest offering we have with EST drivers in the configuration. KZ ZEX comes at a very attractive price tag of just Rs 1949, BUT Is it worth it? How does a low-voltage EST driver affect the performance of such a budget IEM? Well, we are gonna find our answers today.

KZ ZEX-1

Disclaimer:-

I bought the KZ ZEX from Concept Kart myself as I wanted to check out all the hype around it. Concept Kart was kind enough to offer me a bit of a discount in return for a review impression for their website. I am in no way paid or affiliated with Concept Kart, I will try my best to share exactly what I hear with the pair. If you are interested you can buy the KZ ZEX from Concept Kart from the link below.

Purchase here.

Unboxing KZ ZEX:-

The KZ ZEX package is similar to other models by the brand. It is a compact white box with a slip-on cover at the top. We have an image of the pair printed on the top of the slip-on cover along with KZ ZEX branding and driver configuration printed at the front. At the back, we get the technical parameters of the pair printed in English and Chinese and also some brand information. When we pull this slip-on cover from the actual package, we have a transparent plastic sheet protecting the contents of the package. If you have previously bought/tried any KZ or CCA (sister brand to KZ) product, you will notice the package is completely identical to them.

KZ ZEX-2

Contents:-

1. KZ ZEX earphones.

2. 2-pin cable with 3.5mm termination and in-line microphone.

3. Three pairs of silicone ear tips.

4. User guide.

Design & Build:-

KZ ZEX ear shells have a solid build quality. They don’t actually feel like a budget segment earphone with their elegant finish. The shells don’t look like plastic at all, the inner cavities are made up of high-quality solid resin material. The inner cavity has a translucent body, upon lit properly we can see the drivers inside. For elegant design, A matte-finished metallic face cover is attached to the cavities. I have the elegant matte black finish(which in my opinion is the best color option for the pair). As for branding on the earpieces, both the earpieces have a KZ logo printed on the face panel area. IMO, of all the earphones that I have tried near the 2000 Rs price tag that includes Tanchjim Tanya, Moondrop Quarks, and a few more, the KZ ZEX offers the best build quality with its elegance.

KZ ZEX-3

The included cable is the standard KZ ear parallel line cable with an in-line microphone and a single key for media control and calling.

Noise-isolation & Fit:-

Though the cavity body is resin, the attached aluminum alloy face cover adds some weight to the ZEX earphones. Still, the pair is comfortable for long usage. They have over-ear memory hooks on the cable that ensures a comfortable fit. I have medium-sized ears, and I personally feel the pair is comfortable for long listening hours. It effectively reduces ambient background noises providing good isolation for me. I used stock medium-sized ear tips with ZEX for my personal usage.

Sound Quality:-

KZ ZEX is a surprisingly easy-to-drive pair of earphones. I was doubting this as EST drivers are usually power-hungry, but the implementation here by KZ is excellent for the ZEX. I drove the pair easily off my Redmi Note 10 Pro at only about 50% volume for my adequate listening level. Using it with L&P W2 Portable USB DAC improves the output with better resolution and clarity. Now let’s begin on the sound impressions for ZEX.

KZ ZEX-4

ZEX comes at a very competitive price range, but the implementation of a low-voltage EST driver and professional tuning by KZ makes the pair stand out from the competition. It delivers a lively and energetic sound performance with an elevation in the bass region. I personally feel the lower end has more focus on the mid-bass region producing powerful slams with every single bass drop. The sub-bass is also noticeable with the pair though the main focus is always on the mid-bass region. Bass extension is also good for the price point. ZEX actually has a fast bass response that complements the other frequencies very well.

KZ ZEX-5

Midrange with ZEX shows rich tonality & clarity for vocals and acoustic instruments. Vocals have a slightly warm touch to them, both the male and female vocals are presented with a pleasing warm tone. They don’t get harsh or sibilant or fatiguing even at high volume. Though to protect the mid-range from any noticeable bleed from the lower end, lower mids have a slightly recessed presentation. Upper mids again come forward but in a pleasant way. KZ has shown its professionalism in tuning the KZ, the upper mids despite being forward never get shouty(Which is actually a common thing in earphones around this price range).

KZ ZEX-6

EST driver shows its magic with an energetic and smooth presentation in the top-frequency response. The dynamics and instrument separation with ZEX are pretty good. I don’t notice any kind of sibilance or harshness for any track with the KZ ZEX, in fact, I felt the output had good detail retrieval for the price.

KZ ZEX-7

Well, this was all that I personally feel is good with the ZEX. Now some things that I don’t like with the pair in terms of sound. The First would be soundstage, I mean it feels adequately wide and tall but misses out in depth department. Width is also average for the price segment, I can’t say this is the widest soundstage I have heard in the price segment. (Tanya when amp’ed properly has a wider sound field as per me). Imaging, positioning of instruments is again average for the price segment.

Tracks used for testing KZ ZEX:-

1. Tajdar-E-Haram by Atif Aslam(Coke Studio).

2. Blank Space by Taylor Swift.

3. How Does It Feel by London Grammar.

4. Agar Tum Seth Ho Unplugged by MTV Unplugged.

5. Thriller by Michael Jackson.

6. Shivers by Ed Sheeran.

7. Radio Ga Ga by Queens.

8. Save Your Tears by Weeknd.

9. Montero(Call Me By Your Name) by Lil Nas X.

10. Butter by BTS.

11. Royals by Lorde.

12. Birds by Imagine Dragons.

13. Kis Morh Te from the movie Qismat 2.

14. Tum Ho from the movie Rockstar.

KZ ZEX-8

KZ ZEX Vs CCA NRA:-

Both the ZEX and NRA are from the same parent company. These both IEMs have the same driver configuration, 1 DD+ 1 EST, though both of these have got different tuning. Here’s my take between these two.

>KZ ZEX sounds darker in comparison to the NRA, NRA has a slight bright touch to the tonality.

>Both have similar shortcomings in terms of dynamics.

>NRA has boosted midrange, vocals are upfront.

>Soundstage on NRA feels more intimate, ZEX feels wider.

>Instrument separation and detailing is better on ZEX.

>Personally like the stealth look of ZEX, NRA has more color to it.

It’s hard choosing between the two, I will say both the earphones have similar levels of micro-detail retrieval, NRA has more energy in the mid-range and high frequencies, while ZEX has a smoother sound in comparison.

KZ ZEX-9

A Few Final Words For ZEX:-

If I have to summarise my review of ZEX in a few words, I would say ZEX has changed the way I enjoy my music and that too in a better way. I was actually expecting a bright, harsh sound with the ZEX, but to my surprise, the tonality and presentation of KZ ZEX is very pleasing. The pair delivers quality lower-end response with emphasis on the mid-bass region, maintains good clarity for vocals and acoustic instruments, and retrieves great details from the high-frequencies. All these without getting harsh or sibilant even once. Yes, it has its own shortcomings like lack of depth in soundstage and average imaging, but for only 2,000 Rs I can say ZEX is a great option to consider while making your next earphone purchase. Lastly, I am personally gonna use the ZEX for my day-to-day rough usage like gym, jogging, and more. My new daily partner is here with me.

If you are following the Chi-Fi audio scene, you must be familiar with Venture Electronics, the famous brand behind the revolutionary Monk Plus earbuds. I called the Monk Plus revolutionary as they changed the way I enjoy my music, at a mere 799 Rs they deliver so much value with excellent comfort and smooth sound tuning. But today, I am not here to discuss any more about the Monk Plus, I am here to share my impressions on their single DD earphones, the VE Bonus IE(also known as VE BIE).

Introduction:-

VE BIE comes at a very competitive price range(priced at Rs 2,099) where we expect high-performance without hitting the pocket hard. BIE was originally released back in 2019, now the main questions here are, Is it still worth it in 2021? Is it among the best single DD’s out there at its price point with competition from new IEMs such as Moondrop Quarks and Tanchjim Tanya available at around the same price point? We are gonna find out today in this review, let’s begin with the Technical Specifications of the pair.

Venture Electronics BIE-1

Technical Specifications:-

1. Driver size: 10mm Dynamic Driver.

2. Impedance: 32Ω.

3. Sensitivity: 115dB.

4. Frequency Range: 17Hz-22kHz.

5. Matte Finished Aluminum Alloy Shells.

6. In-line mic cable with 3.5mm termination.

Disclaimer:-

I bought the VE BIE at retail price from Concept Kart, India for my personal use. If you are based in India and are looking to buy BIE, you can buy it from their store from here. (I am not affiliated neither is the link).

Package & Accessories:-

VE Bonus IE comes packed in its rectangular zipper carry case. It is similar to that of what VE includes with some of its earbuds like the Monk SL. The outside has a denim style blue finish with Venture Electronics branding logo. Inside we have the VE Bonus IE sitting with its cable wrapped around it. The package includes four pairs of silicone tips. I am surprised to see a zipper carry case included at this price point with an IEM. The other two that I currently have with me, Quarks and Tanya just included a carry pouch.

Venture Electronics Bonus IE-2

What I Got:-

1. VE Bonus IE.

2. Four pairs of silicone tips.

3. Zipper carry case.

Venture Electronics Bonus IE-3

Build-Quality:-

Tank, Built-Like a Tank. Yes, these are the exact thoughts that came into my mind when I first saw the Bonus IE. The shells have a bullet-shaped simple form factor with matte-finished aluminum alloy cavities with non-detachable cable. They are very compact and can be used around easily. With a fully metallic build they offer robust build quality, looks like they can easily take a beating or rough usage. The earpieces have a very light golden tone to them. I am super happy with the build quality of Bonus IE, just non-detachable cable keeps bugging me. I am not good at handling my earphones, usually, damage my earphones by stretching the cable(4-5 earphones with non-detachable cable have died one me due to this reason). Other than that an exceptionally good build with the BIE.

Venture Electronics Bonus IE-4

Fit & Noise Isolation:-

Being fully metallic, the earpieces do carry some weight but they are comfortable for long listening sessions due to their compact form factor. I wear them simple cable down way. BIE covers my ear canal completely blocking any chances of outside noise peeking in, very good isolation from the background noises.

Mic Quality:-

I bought the VE Bonus IE with an in-line microphone(only this edition is available here with Concept Kart). The mic quality is very good. There are no complaints if you use it for your office calls. The voice transmission is clean. There is no background noise reduction at this price point.

Venture Electronics Bonus IE-5

Sound Impressions:-

Before beginning on the sound impression part, I must say the VE Bonus IE is fairly easy to drive earphones. You don’t need any fancy gear to enjoy the best with the Bonus IE. It offers exceptionally good performance straight out of a 3.5mm jack on smartphones too. I used Redmi Note 10 Pro, Redmi Note 9, and there were no issues at all. Obviously, using the pair with better quality hi-res players or USB DAC/AMPs improves its performance with a wider stage and deep punch from the lower end.

Venture Electronics Bonus IE-6

Love some bass? VE Bonus IE will satisfy your hunger for good bass with its deep-hitting powerful lower-end response. The pair has a smooth U-shape tuning with an elevated bass response. Bonus IE will take you diving deep into your music with its powerful bass response pretty evident from the track “Why So Serious by Hans Zimmer”, you will notice every single beat dropping hitting deep right into your soul. I would say even the bass heads will satisfy with this punchy performance. For me, It complements my regional Bollywood music well, I love those quick punches complementing the other frequencies very well. The entire lower end sounds emphasized, both the mid-bass and sub-bass regions reach deep depths. “Contact by Daft Punk”, “Yaar Ni Milyaa by Hardy Sandhu”, both show the strengths of Bonus IE.

Venture Electronics Bonus IE-7

Despite its powerful lower-end response, Bonus IE has good clarity in the mid-range with clean and rich vocals. Yes, there is an occasional bass bleed into the mid-range but the pair maintains good clarity by taking the lower mids a bit backward(Recessed). Vocals take the front space again with elevation in the upper midrange. Vocals have a warm tone to them that makes them sound very pleasing and musical. I personally find the pair to show a clean vocal response despite being such powerful in the lower end, It shows a mature and professional tuning by VE. Though there is a slight lack of air in the midrange you will still be able to enjoy pop, rock, and other genres with good clarity for vocals.

Venture Electronics Bonus IE-8

The Treble region has got a safe in-offensive sound tuning, there is no noticeable sibilance or fatigue. You can listen to the pair for hours without feeling tired at all, thanks to its smooth non-fatiguing treble response. The lower treble region has good details with good extensions too. You will notice cymbal crashes are not splashy or sparkly, rather have a smooth nicely extended presentation. I am thankful for this as I am quite sensitive to harsh treble and peaky/sparkly treble makes me fatigue after short listening sessions only. Though with this safe tuning, the takeaway here is the lack of minute details. Detail retrieval is not the best with the Bonus IE. This is highly noticeable in fast & complex tracks such as “Rockstar by Ali Zafar”, till the song has a smooth and slow presentation the detailing is excellent but as soon as the song picks up speed and multiple instruments are presented at the same time, it becomes difficult to pinpoint or separate each one of them. Though this is just me nitpicking, at its price point couldn’t expect better.

Soundstage:-

VE Bonus IE soundstage is into the head with good depth. Depths can be felt with deep hitting bass response, though the stage width and height could’ve been slightly better. With this intimate presentation, the experience is immersive. Separation and Imaging are above average for the price point.

Venture Electronics BIE-10

VE Bonus IE Vs Tanchjim Tanya:-

Tanya came out earlier this year, housing a single DD configuration. How well does Venture Electronics Bonus IE compare with the Tanchjim Tanya?? Here are my thoughts.

>Build quality of Bonus IE is exceptional, nothing beats that at its price. But Tanya at the same time has lightweight aesthetics, allowing for a more comfortable fit.

>Tanya is a demanding set. To experience it at its best, you need to power it well(Usually takes a portable amp too). Bonus IE can be driven straight off your smartphone.

>Both have non-detachable cable.

>Bonus IE includes a carry case.

>Bass response of Bonus IE is impressive.

>Both IEMs have a similar treble presentation with Tanya being slightly better extended.

>Tanya has a wider stage among the two.

It completely depends on the use case scenario and sound preferences with these two. I prefer Tanya for a natural listening session, while Bonus IE for a fun and engaging session. Both stand good at their own place. Though easy drivability is a big plus in Bonus IE’s favor.

Venture Electronics BIE-11

VE Bonus IE vs Moondrop Quarks:-

Quarks is available at a slightly lower price point, tbh exactly half the price of Bonus IE. How well do these two compare? Let’s find out.

>Bonus IE sounds cleaner among the two. Quarks has a slightly grainy texture to its output.

>Build quality-wise, Bonus IE takes many points in its favor with a full metallic build, Quarks have a plastic shell and a sticky cable.

>Quarks are very very comfortable to wear.

>Carry case with the Bonus IE, Carry pouch with the Quarks.

Both in terms of accessories, sound and build Bonus IE looks like a direct upgrade over the Bonus IE. But that comes at around twice its price so that was kind of expected between these two.

Final Conclusion About VE Bonus IE:-

It isn’t a surprise that the VE BIE is an excellent performer. It does everything right, starting with its superb build to excellent sound performance, it does everything perfectly for its price point. I personally loved the fun factor the BIE brings to my music sessions without hitting my pocket. I despite having some high-end stuff, keep the VE BIE as my go-to pair every now and then for a casual and fun listening session. If I have to nitpick some issues with the set, I would say only one and that’s its non-detachable cable. But I heard Venture Electronics has now released a new Bonus IE Pro with a detachable MMCX cable design. It would be a perfect set. I hope Concept Kart will bring the Bonus IE Pro here too!!

You can listen to the pair for hours without feeling tired at all, thanks to its smooth non-fatiguing treble response. The lower treble region has good details with good extensions too. You will notice cymbal crashes are not splashy or sparkly, rather have a smooth nicely extended presentation. I am thankful for this as I am quite sensitive to harsh treble and peaky/sparkly treble makes me fatigue after short listening sessions only. Though with this safe tuning, the takeaway here is the lack of minute details. Detail retrieval is not the best with the Bonus IE. This is highly noticeable in fast & complex tracks such as “Rockstar by Ali Zafar”, till the song has a smooth and slow presentation the detailing is excellent but as soon as the song picks up speed and multiple instruments are presented at the same time, it becomes difficult to pinpoint or separate each one of them. Though this is just me nitpicking, at its price point couldn’t expect better.

Soundstage:-

VE Bonus IE soundstage is into the head with good depth. Depths can be felt with deep hitting bass response, though the stage width and height could’ve been slightly better. With this intimate presentation, the experience is immersive. Separation and Imaging are above average for the price point.

VE Bonus IE Vs Tanchjim Tanya:-

Tanya came out earlier this year, housing a single DD configuration. How well does Venture Electronics Bonus IE compare with the Tanchjim Tanya?? Here are my thoughts.

>Build quality of Bonus IE is exceptional, nothing beats that at its price. But Tanya at the same time has lightweight aesthetics, allowing for a more comfortable fit.

>Tanya is a demanding set. To experience it at its best, you need to power it well(Usually takes a portable amp too). Bonus IE can be driven straight off your smartphone.

>Both have non-detachable cable.

>Bonus IE includes a carry case.

>Bass response of Bonus IE is impressive.

>Both IEMs have a similar treble presentation with Tanya being slightly better extended.

>Tanya has a wider stage among the two.

It completely depends on the use case scenario and sound preferences with these two. I prefer Tanya for a natural listening session, while Bonus IE for a fun and engaging session. Both stand good at their own place. Though easy drivability is a big plus in Bonus IE’s favor.

VE Bonus IE vs Moondrop Quarks:-

Quarks is available at a slightly lower price point, tbh exactly half the price of Bonus IE. How well do these two compare? Let’s find out.

>Bonus IE sounds cleaner among the two. Quarks has a slightly grainy texture to its output.

>Build quality-wise, Bonus IE takes many points in its favor with a full metallic build, Quarks have a plastic shell and a sticky cable.

>Quarks are very very comfortable to wear.

>Carry case with the Bonus IE, Carry pouch with the Quarks.

Both in terms of accessories, sound and build Bonus IE looks like a direct upgrade over the Bonus IE. But that comes at around twice its price so that was kind of expected between these two.

Final Conclusion About VE Bonus IE:-

It isn’t a surprise that the VE BIE is an excellent performer. It does everything right, starting with its superb build to excellent sound performance, it does everything perfectly for its price point. I personally loved the fun factor the BIE brings to my music sessions without hitting my pocket. I despite having some high-end stuff, keep the VE BIE as my go-to pair every now and then for a casual and fun listening session. If I have to nitpick some issues with the set, I would say only one and that’s its non-detachable cable. But I heard Venture Electronics has now released a new Bonus IE Pro with a detachable MMCX cable design. It would be a perfect set. I hope Concept Kart will bring the Bonus IE Pro here too!!
