[Machine Translation] [PC Triple C conductor with stable electrical characteristics of ultra low distortion and high conductivity is used. It realizes a wide dynamic range and high S/N ratio. In consideration of the skin effect, a single wire is used for the center conductor and an ultra-fine wire is used for the outer circumference. [Insulator] Foamed polyethylene with low relative dielectric constant is used to increase transmission speed and contribute to high sound quality. [Shield] Copper foil shield structure is used to provide a stable shielding effect. [Silk, which is resistant to noise and static electricity and has elasticity and flexibility, is used. [Conductor] PC-Triple C (single wire in the center conductor and double-layer structure of ultra-fine wire in the outer circumference) [Structure] Independent twisted pair cables for left and right [Interconnections] Silk thread [Cable outer diameter] 2mm x 4mm
