Upgraded High-Purity Silver-Plated Cable as a Standard Accessory

The silver-plated twin cable has excellent electrical conductivity, and its design further enhances this conductivity. By reducing electromagnetic interference through twisted pairs, it can reduce the loss of audio signals during the transmission process, thus improving the sound quality performance.

In addition, the silver-plated cable has good antioxidant properties, which can greatly extend the service life of headphones. Meanwhile, thanks to the design of the twin cables, the earphones are more convenient to carry and are no longer troubled by wire tangling.

Simple and Practical Eco-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.
