How to use

Connect the detachable cable to a suitable headphone output on your amplifier, DAC, or audio interface.

Use with high-quality headphone amplifiers or DAC-equipped sources to achieve optimal dynamics and detail.

Store the headphones in a dry place and disconnect the cable when not in use to extend component life.
