Breaking Through Technical Barriers Original Ultra-Wide Frequency Dynamic Driver
Innovative Technological Breakthrough
While many brands are busy hyping up their diaphragm technologies, we have already focused on developing higher-performance, high-dynamic, ultra-wide frequency dynamic drivers. The KZ Libra model features an ultra-wide frequency dynamic driver with a high-precision internal welding structure and a magnetic gap of approximately 0.1mm. These two characteristics are enough to surpass most conventional dynamic drivers, as any diaphragm material pales in comparison to structural innovation.

Simple, Practical, and Environment-Friendly Packaging
What’s in the box
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 KZ’s beliefs since its founding.
