Targeted development of second-generation balanced armature

New reed structure design
Comparison of differences in reed structure
The traditional "U" shaped reed is designed for hearing aids, and its bending process may lead to poor stability and consistency.

This time, we specifically designed a "Trident" reed for HiFI earphones, which is more accurately centered between the magnets. This design can enhance sound density, reduce distortion, and achieve better transient performance.
Comparison of differences in sound
Compared to all previous balanced armatures, the newly designed 22955 BAcan deliver more powerful and resilient bass.

The new generation 29689 BA can deliver spacious, elegant, natural sound with superior treble extension.

Simple, practical, and environment-friendly packaging

We believe that products do not need to be packaged in luxury because the actual performance of products can not be presented in packaging. We advocate environmental protection, but we will not make high profits in the name of environmentalism, which has been one of the beliefs of KZ since its founding.
