16 core 6N pure silver plated gold-plated replaceable IEM cable upgradable mmcx IE900 kz zs6 Earphone cable

High frequency transparent and delicate. The gold plating layer optimizes high-frequency signal transmission, extends naturally and smoothly, reduces burrs, and provides clear and non irritating instrumental overtones. Medium frequency density enhancement. Single crystal copper OCC has a uniform molecular structure, which creates a solid and full connection between human voice and musical instruments, making emotional transmission more infectious. The gold plating layer optimizes the transmission of high-frequency signals, extending naturally and smoothly, reducing the feeling of burrs, and making the instrumental overtones clear and not harsh. Low frequency diving deep. The low resistance characteristics of single crystal copper improve current conduction efficiency, with fast low-frequency dynamic response, balanced sensitivity and elasticity, and clear hierarchy. High background purity. The gold plating process reduces the risk of oxidation on the contact surface, combined with a sh
