Features 1、The twisted pair twists the hot and cold signal wires to offset the magnetic flux caused by the current and reduce signal transmission loss. 2、It can reduce the influence of current noise caused by the external magnetic flux passing through the connecting wire. Therefore, high‑resolution sound with scene feeling can be realized. 3、The core OFC copper wire has good electrical conductivity, bright and shiny surface, and has high corrosion resistance. 4、It can improve the resolution and separation of the earphones, and eliminate the dull bass sound of the earphones. 5、Make the sound more transparent, natural and beautiful.
