The signal line made of 102 SSC Precision Conductor boasts a generous 0.3 square meter diameter. It faithfully transmits delicate headphone output, from delicate high frequencies to powerful low frequencies. The 100% pure silk filament used in the inclusions and outer jacket effectively suppresses static electricity and vibration, significantly reducing noise, delivering high-resolution, clear sound.
