The Truth About Planar Drivers

KZ PRX features a genuine planar driver, not a gimmick
Many so-called planar drivers on the market are simply dynamic drivers with reduced voice coil height, which are fundamentally different from the genuine planar driver! In recent years, some brands have introduced the so-called "planar magnet driver" merely to capitalize on the popularity of the true planar driver, misleading consumers with gimmicky products. Essentially, these are just dynamic drivers with reduced voice coil height, relying on 2-4 magnets and a coil to produce sound. They have low sensitivity, poor high-frequency performance, and even lower transduction efficiency than traditional dynamic drivers. These products often target inexperienced users with flashy marketing. In contrast, KZ PRX features a true planar driver consisting of at least 14 high-performance magnets and does not use a traditional voice coil, resulting in excellent high-frequency extension and a wide soundstage.

What Defines a True Planar Driver?

Innovative design with ultra-light voice coil for superior high-frequency response
A genuine planar driver is characterized by its unique design: unlike traditional dynamic drivers, it features a voice coil that is uniformly coated with approximately 5μ of conductive silver through an electroplating process. This innovative design significantly reduces the mass compared to the heavier voice coils found in dynamic drivers. As a result, the diaphragm experiences less inertia, enhancing its ability to extend high and ultra-high frequencies.

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.
