Sennheiser - HD 660 S


The new HD 660 S (replacing the HD650 with updated transducers) lets you enjoy sophisticated audiophile sound in even more listening situations. Thanks to the new lower impedance transducer design, it delivers reference-class sound also when connected to hi-res mobile players, thus offering much greater versatility. The HD 660 S is designed and engineered to be very comfortable, while still being elegant and able to indulge the demanding listener with aural precision.
