Innovative Technological Breakthrough

Breaking Through Technical Barriers

Original Ultra-Wide Frequency Dynamic Driver
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.

Balanced Version & High-Resolution Version

Performance and Acoustic Parameters Surpass Those of High-Premium Earphone Products

We have designed two versions of the KZ Libra: the Balanced Version and the High-Resolution Version. The Balanced Version offers a well-balanced frequency response suitable for various music styles. The High-Resolution Version delivers enhanced detail resolution, a wider soundstage, and richer details, making it ideal for professional users with higher audio quality demands. Both versions effortlessly surpass the performance of most high-priced single dynamic driver earphones from other brands.

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 KZ's beliefs since its founding.
