The end of connecting the power plug to the power cable is made of fluorine resin (PTFE) tape with excellent insulation and vibration dampening, and the cable outer shell uses a braided protective tube (monofilament) with excellent vibration resistance. The end of the cable is also soldered to prevent twisting. This solder uses an audio grade lead-free solder that is used to produce high-end audio products and is environmentally friendly.
