Electrostatic Driver and Dynamic Driver Hybrid Technology

Using the current advanced hybrid ways, the 6.8mm low-voltage electrostatic unit and the 10mm dual magnetic dynamic unit cooperate with each other, bursting out shocking detailed analysis and super cool listening atmosphere.

High-density Sound

Compared with other types of sound units of the same specification, the performance is superior and the quality is more stable. It is suitable for expanding the high-frequency matrix and performing a deeper interpretation of music data.

Better Than A Balanced Armature

The sensitivity of the electrostatic unit is better than that of the dynamic unit in the 20kHz frequency band. The breakthrough in hardware brings a deep and ethereal whale sound effect, just like a whale humming in the ocean, with a vast sound field and an immersive atmosphere.

Easier to Drive

The newly developed low-voltage electrostatic unit, listening for 5 minutes is enough to stimulate the unit’s potential, and only a little current is needed to show strong performance potential. You can also enjoy HiFi-level professional sound quality when connected to a mobile phone.

Ergonomic Design

The cavity contour designed in combination with the big data of the auricLe and the ear canal, and the delicate and smooth surface treatment bring a comfortable wearing experience for the listener.

Customer Reviews

Based on 2 reviews
Impressed in a very good way !

Pair in Graphite color / mic
Same old packaging from KZ but for once what a nice simple cable !!! I'm still not used to a simple plastic tube for the ear hook it lacks flexibility, it should be heat shrink . Medium size tips are perfectly fine. So, for once a KZ is ready to go and play, that's a change ;)
Sound wise the ZEX blew my mind with its wide sound stage, I mean I don't care much for depth and instruments positioning as I listen Electronic and sub genre most of the day aka "home mixed". I'll it a shot later with professional Studio Mixing Recordings, Dune 2021 OST , Lives ... so on.
Last, but not least : ZEX has great tonality, precise, response is fast enough with Breakbeats, no outpouring in some specific frequency range and vocals [females] are well placed not out of step in any way. I think I could wear them of a couple of hours, no prob. very pleasing.
I think the Electrostatic + Dynamic is a winning pair.

A New Era in IEM's

Just in Awww of what $25 can get you in sound quality as of today. Mid-bass hits really nice, sub-bass is felt and there's just a little warmth rising up to give the Mids and vocals a little thickness/weight. Treble extension is a little lacking, but this gives it a very easy & long listening experience, and still there's some energy to give everything life. Stage isn't wide but nothing sounds like it's congested, and there's nice detail retrieval. If you like this but want a little more sparkle than try their NRA, both are fabulous. Built is very good, even comes with a metal faceplate, and I can't say enough about how good this looks. Plays easily on a smartphone and sounds just as good as if it was played on a dac/amp, doesn't need a lot of power. Vocals are just a hint closer than natural, but this is what I prefer, and there's no harshness and no shoutiness and it doesn't interfere with instrument imaging. Overall, I'm very pleased and can't wait to see their future implementations of this new driver!
