Simply Amazing.

Prior to purchasing this earphone I always went with a pair that cost below Rs.3000. Since I was shelling out about Rs.5000 for the KZ ZSX, I was expecting a significant jump in sound quality and I am happy to say that ZSX has not only met my expectations but exceeded them.

Before I made the purchase, I called the HeadphoneZone helpline to get a recommendation for an earphone that had good punchy deep bass but didn't compromise the high and lows and this earphone gives me just that. So, shoutout to the guy who made the recommendation.

For anyone else thinking about buying this earphone do keep in mind that it takes a bit of use and burning in for the lower end of the earphone to really shine and reach its potential.

It's not all perfect though, while the sound quality is fantastic, these earphones do lose a few marks for me in the comfort and build quality area. The cables that come with this are of the braided kind, and usually braided cables give me ease of mind that they won't break but these don't seem thaaaat durable. As far as comfort goes, if possible try em out to see how comfortable they feel before making the purchase. They don't hurt my ears or anything, but need a lil bit of adjusting every half hour or 45 mins or so.

Not wanting to end the review on a sour note, let me just reitirate again these sound amaaaazing. If you are willing to make SMALL compromises in the comfort and build quality aspects, in order to get earphones that sound next level compared to the

We are incredibly grateful that you took the time out to leave us this note. We look forward to serving you again.

12 Driver madness

KZ has a reputation of being addressed as YAKZ (Yet another KZ)...They have released so many IEMs and continue to do so. I have tested almost 6 of their IEMs and I can say with certainty that this is the brightest without being harsh... One caveat though....Needs proper 72 hrs burn-in.... You will then see how they mature. So delightful to hear. ZSX puts many high end IEMS to shame... The build is classy with a resin body and a Zinc top plate. The cables and connectors are better this time and not the crappy cable they supply with other IEMs. The highlight is the sound. Sometimes it is not possible to explain ecstasy. But trust me.... It sounds fantastic after the burn-in... Out of the box it sounds dull....Packaging is minimal.. I listen to MQA recordings on Tidal on UAPP+Cobalt+ZSX; Or Tidal + LG V40 thinq + ZSX....

Thank you for sharing your review with us.

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.

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.


The KZ ZSX is another successful hybrid driver in-ear headphone from KZ Acoustics. It includes DWEK BA drivers for medium and high frequency, one DD for low frequency and one 30095 driver for high frequency which features high quality of driver configuration. These in-ear headphones deliver a powerful and dynamic sound with an improved high frequency.



You can experience the smooth and sensible sound as these in-ear headphones have a reasonable cavity structure which balances the vocals of the unit and delivers a rich and deep sound performance.



The cavity is made out of cochlea, covering its large part. These earphones are nicely moulded to give you an amazing fit, like it is made for you. Because of its special design it can effectively isolate the sound around you and give a better sound quality. You can now enjoy your music to the fullest.



The KZ ZSX is made up of two different material: Zinc alloy to give an elegant look and glitter to the face plate and the cavity is made up of imported resin which makes the in-ears durable. The detachable gold plated 2 pin cable is an upgrade to these in ears while the limited slot protection design acts as a savior to the pin from breaking adding more life to the cables.
