A new audiophile versatility

Enjoy the HD 660 S sound in even more listening situations. Thanks to a lower impedance than the previous HD 650 model, they deliver reference-class sound when connected to high-res mobile players. They indulge the demanding listener with aural precision and a comfortable fit.

With an impedance of 150 Ohms and a frequency response of 10 Hz to 41 kHz, the HD 660 S headphones are equipped with a choice of cables that feature both balanced (4.4mm Pentaconn) and 1/4" connectors. A 1/4" to 1/8" adapter is also included. This allows you to enjoy reference-class, high-fidelity sound with stationary and mobile audio players alike.

Cutting-Edge Technology

Built with a transducer design that improves control of the diaphragm movements, the headphones are manufactured with precision stainless-steel fabric that adapts to the contour of the diaphragm. Aluminum voice coils ensure high impulse fidelity. Transducers are carefully selected and paired by hand to ensure consistently narrow tolerances (±1 dB).
