* Electrostatic driver + Dynamic Driver： KZ ZEX is the first dual-driver-electrostatic&dynamic hybrid driver in-ear earphone from the KZ brand. The music distortion rate is even lower than the balanced armature.

* High-density Sound： Benefit from the high-density sounds and hi-res audio performance of the electrostatic KZ ZEX with better vocal resonance, louder and clearer sounds performance. 

* Better Than A Balanced Armature： In the same 20KHz high frequency, its sensitivity has even better performance than a balanced armature.

* Easier to Drive： Compared to the traditional high-voltage electrostatic driver, low-voltage electrostatic is much easier to drive in slim-sized earphones.

* Much More Stable： The better performance for low-voltage electrostatic technology, quality consistency is much more stable than dynamic & balanced armature.
