Description
The HD 660 S Open-Back Dynamic Headphones from Sennheiser are headphones for the passionate audiophile and are crafted for the most demanding listener.

Built with a transducer design that delivers lower harmonic distortion, they provide a natural, lifelike audio experience and can be used to produce crisp bass, transparent mid-frequency response, and a natural treble when connected to high-res players or portable audio devices.
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.
