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.

Left side DD died after few months of use

Overall they were pretty ok while working well, but well the left side DD died, although the EST still is audible.


Fits perfectly, ideal for stage

Way too bright for me.

I ended up with Shure SE-15's

Great IEMs and great customer service!

The IEM cable was defective so I contacted Linsoul and they shipped out a replacement cable. Cable works great and the KZ ZEX are awesome IEMs and are really affordable. Purchased 3 more after buying my first pair and gave them out as gifts. Thanks!

Too Much Bass For Me

There was so much bass slam that it was all I could think about when listening to music.
I gave them away a while ago, so I can't remember too much about the rest of it.
If you want something cheap with good bass slam, then buy the CCA CRA instead.
Its also cheaper.

not bad for the price but not good either

bass is a bit too strong for this to really shine I found the ZSN PRO X to have a better tuning (better bass control and more well rounded)

Nichole De Guzman
One of the best service and iem

I really love linsoul audio's service fast and reliable, now for the KZ ZEX, it's so fun to listen not that detailed compared to my other iem but one of the best sound stage musicality and fun iem but relaxed.
