Customers praised these budget IEMs for "amazing sound quality" with excellent clarity, detail, and instrument separation. Many noted "punchy deep bass" and wide soundstage. Common concerns included harsh highs at higher volumes, recessed mids, and poor cable quality. Some found them uncomfortable for extended wear. Best after 24-72hr burn-in.

  • The clarity is awesome, the low mids and high all sound great
  • It can compete with the Apple AirPods Pro, which is 4-5 times the price
  • Amazing bass and good detail. Worth the money

The Terminator Beast- Better than AirPods Pro

Never knew what is an(IEM) In Ear monitor, after buying this KZ ZSX Terminator, I can say that it can compete with the Apple AirPods Pro, which is 4-5 times the price of KZ ZSX.

A total of 12 Drivers, 1 Dual Dynamic drivers for Powerful and Puncty Bass, 5 Dual Balanced Armatures to handle Lows, Mids, Highs and treble. Great Instrument Separation. I've used it for a month and all I can say is, it gave me the best ever sound experience.

A good part about IEM is it can be used as Wired, Neckband and can be converted to Truly wireless as well. Which was a surprising for me.

The soundstage of this earphone meant to be average. But it can be tuned to produce a better one. But when it comes to wire KZ really needs to improve the cable, it looks very cheap in terms of design. The eartips were found cheap, I replaced the KZ eartips with my Fav V-Moda Forza Silicon eartips, I can say that for me this worked as the finest fit.

I recommend to play a FLAC file, as it gives the best audio experience than 320KBPS MP3 format.

Please give some hours of burning time to the IEM to produce that awesome sound. IEM gets better with time.

So glad to know that you love them:) We look forward to serving you again. Happy listening!

Fine But Not Good At This Pricepoint

As i have Used So many Headphones and Earphones in my Whole Life I Can Surely Say This is Not As Good As Comparing with its Price,I have Used a Varieties of Earphones from Some Premium brands Such as Apple,Sony,Philips,Tribit,SoundMagic,Senheiser and now KZ ,I Can Truly Say that the APPLE EARPODS are Massively Better than All Other Earphones i Used So far,Actually I'm Very Excited about the purchase of my first IEM,but i am Hugely Dissappointed first of all,the wire of KZ ZSX is not as good as other IEM's,The Outer Cladding Plastic is only at the Earphone Wearing Area and The Rest of the Wire is not Coated so that in my hands its Producing a Moisture like Substance,its Very irritating and in terms of Comfort its Not Good for Persons with Small ear Holes,it will Cause pain if using for a while,And Most Important thing is the Sound Quality,The Bass is Overpowered and it hides the Mids in Almost All Songs i Tested,
May be KZ AS10 can Resolve it,but i didnt know about it,but it is the most Top Rated KZ's Earphone So Far in terms of Sound and Price..
I Can't Feel that it Contains 6 Drivers in Both Side,I Tested it With My Huawei Nova Plus Which has an Excellent Audio Output in the Smartphone Universe,it Definetly Lacks Some Thing,Sound detail is Ok,but Some Thing Fisshy,

FINAL VERDICT: All i can say is that,Apple Earpods is my Best Earphone Experience So Far in terms of Lows,Mids,Highs,Bass n Treble it has an Extreme High End Sound Quality for Such an Affordable Price,Detail in Sound is Amazing.......

My Rating for KZ ZSX as Compared with Apple Earpods:
Apple Ear Pods : 10/10 ;
Kz Zsx : 07/10 ;
Thank You.......................................................................................

Thanks a ton for the review!

Great IEMs for the price

This is my first experience with an iem. I am no audiophile and was sceptical about getting an iem as i was not sure if it will suit my listening style. So I went for a relatively cheaper one with KZ zsx and I was just blown away when I experienced them for the first time even without burning them in. I used them with soundmagic a30 dac/amp combined to stream 320kbps quality mp3s from my phone and they just sound awesome. The overall clarity is awesome, the low mids and high all sound great. The instrument separation is great and soundstage is wide enough. The base is not overpowering but well balanced without any distortion and the trebles are crisp but not harsh.
I have burnt them in for about 24hrs now and they sound even better.
I have had a pair of Sony xb50aps, senheiser cx 275s, house of marley redemption songs and currently have sony wf- xb700s and Sony wh1000 xm2s but what i feel is that the clarity of this zsx is better than all of them when I combine them with the dac/amp.
So it's a great purchase for me and may be I will go for the pricey ones like the mezes or astell and kerns in future.
Thanks Headphone zone for curating a large number of audiophile level gears which otherwise wouldn't been possible to get in India.

So glad to know that you love them:) We look forward to serving you again. Happy listening!

Good product

Day one of experience:
Thanks to headphonezone and bluedart for quick delivery.

Pros:
1. Build Quality and looks of the IEM modules are very good.
2. perfectly fits in my ear
3. Sound quality is very good. Earlier I used Bose SSW. This is the first time I am trying an IEM , so initially I was little confused. However I liked the sound of this IEM :).
4. Checked the frequency response, I could hear as low as 25Hz and as high as 16kHz with normally. I could hear higher frequencies with extra attentions.
5. Though I am yet to test it in a noisy area, but I feel its noise cancellation is good,
6. The Microphone is decent. recording quality is good, though little noise is audible. Overall good mic for general purpose use (ph call).

Cons:

1. Wire quality is decent. But it could have been better. It is not tangle free. So need extra care to keep it organized.
2. It is little heavy for ear. Might feel uncomfortable to use for long time .

Overall the product is very good and I liked it. Its not for heavy bass lover, but it has decent bass response.

Thanks

These are phenomenal !!!

i had to secretly buy these gorgeous iems as a while back I bought LG G8X with supported quad dac tuned by meridian. I was suggested that these would provide reasonable potential of those dacs working, And yes ZSX sounded beautiful, I have tried the cca c12 as well which were more leaned towards the low ends, these have much presence towards mids and yes the soundstage is very wide. I did the tests after burning them for 24 hrs straight. I love them.
Thank you headphone zone for the quick delivery and of course providing cod to more and more towns. Like I have said earlier, you've got a loyal customer here :) I am sold.

Amazing

I have been using Sound Magic E10c for the past few years. Quite liked them until i heard the same sound files on the ZSXs today. Ive been one of the crowd funders for Neil Young's Pono player and sensibly graduated to more compact DAPs. Always knew i needed to upgrade the headphones to match the DAP and now i understand what difference a good set of plugs can mean when hooked with a decent DAP. Amazing!!!! Worth the price for sure.

V shaped indeed....

I bought these after reading people praising it's excellent details in high and sub low bass. After few hours of burn-in with my songs collection, I could say that these are enjoyable/fun IEMs. It takes sometime to get adjusted to large IEMs and easily tangled cable. In terms of sound quality, i find that there's good amount of low end bass but lacks definition, meh mids and slightly tinny forward highs.. I use these mostly for listening modern pop/ hip hop songs.

I would have rated higher if these came with decent eartips & good quality cable. & Might be it's just me but mic doesn't work on mine.

KZ ZSX

Fell in love with the earphones right from the first song. The bass is amazing and there's good amount of detail which I've never heard in other earphones that I previously had. Volume is high enough making amplifiers less necessary. It gives an immersive experience and the seal is good. For a price of Rs. 5000 these are extraordinary. Worth the money.
