26 ohms (impedance) / 6Hz-26kHz frequency response / Ultra-clear sound reproduction w/ virtually no distortion / Scratchproof, ultra-tough construction

Designed with the expertise of Technics Sound engineers, these premium in-ear headphones are made with Zirconia to give audiophiles pure sound in a durable and stylish design.

In addition to realistic sound, the durability of Zirconia offers audiophiles a scratchproof, ultra-tough construction for a lifetime of use. They even have detachable wires, which can be replaced if they fray, as the Zirconia headphones outlast wires in the long run.
