High Performance Dynamic Unit

KZ ZVX is equipped with a 10mm dual cavity super linear dynamic unit. Unlike the same type of unit used in those expensive earphones, we have made various innovations based on this dynamic unit. We use a diaphragm about 4.8 microns thick on KZ ZVX. Compared with the traditional diaphragm, the mass is significantly reduced to improve the overall vibration sensitivity and make the sound without losing any fine details.




Four Layers Of The Voice Coil

The traditional dynamic unit mainly equipped a double-layer voice coil. The primary consideration is reserving ample space between the T-iron and the magnet. Avoid NG caused by dimensional tolerance caused by the assembly process. This time, we used a four layers voice coil design on the KZ ZVX and reduced the magnetic gap from about 0.3mm to about 0.15mm. The low-frequency performance is more powerful than the traditional dynamic unit with a double-layer voice coil.




Incredible Appearance Design

KZ ZVX adopts a full-metal shell, completely following the process of luxury accessories. Each step is strictly controlled from die casting, CNC, grinding, polishing, electroplating, and laser to ensure a perfect overall appearance. The above makes KZ ZVX a reference design model for similar products.




Ergonomic Design

KZ ZVX uses geometric and modernistic curve aesthetic design and continues the classic ergonomic appearance of KZ products. Let it not only have an artistic appearance but also have an excellent wearing experience.

High-Purity OFC Cable With Widely Compatible 2-Pin Interfaces
KZ ZVX is equipped with high-purity oxygen-free copper flat cable, which has high signal transmission efficiency and ensures good sound quality. You can switch different wire styles with the widely compatible 2-PIN interface according to your listening preferences to enjoy music freely.

KZ ZVX is now available at Linsoul and other locations for $19.99.
