1、Using pure copper as the insert, the electrical signal and current can reach the speed of light transmission rate, solving the signal distortion. 2、The surface is treated with unique insulation, anti‑oxidation, and wear‑resistant special process, which has a good shielding effect. 3、Passed CE / ROHS / PSE certification.Exquisite electroplating process can improve conductivity and reduce magnetism. 4、The first layer‑oxygen‑free copper, which can improve conductivity. The second layer‑silver‑plated, greatly reduces the magnetism. 5、The third layer‑palladium plating, high hardness and wear resistance. The fourth layer‑24K gold‑plated, not easy to fade. 6、Nylon/glass fiber front body runs quietly-higher noise reduction effect can be achieved after installation.
