1Using pure copper as the insert, the electrical signal and current can get to the speed of light transmission, effectively solving the signal distortion. 2Exquisite electroplating process can improve conductivity, reduce magnetism, corrosion resistance, strong wear resistance. 3The shell is treated with a unique insulation, oxidation resistance, and wear-resistant special process, which has a good shielding effect. 4The front body of nylon/glass fiber keeps it quiet during operation and achieves higher noise reduction effect after installation. 5With CE/ROHS/PSE certification to ensure its compliance and safety, it can be applied to professional audiovisual appliances.
