Sennheiser HD 660S headphones

Sennheiser HD660SSennheiser HD 660S have new, more advanced transducers and a lowered impedance. This makes them more versatile and capable of working with both stationary audio equipment and mobile HiRes players with equal high quality.

In addition to fantastic audio potential, the headphones stand out with an elegant design and unprecedented build quality. Even the most demanding users are pleasantly surprised not only by their sound but also by their level of comfort. With the HD 660S, you can listen to truly beautiful sound that is vivid and highly expressive, with clearly defined lows, meticulously crafted mids, and extremely smooth highs. The sound is exceptionally accurate and crystal clear, revealing every emotion and nuance of a musical composition. The lowered impedance of just 150 Ohms means that the HD 660S deliver top-quality sound from both high-class stationary HiFi audio systems and mobile HiRes players.

However, the HD 660S fully realize their very considerable potential when connected to the balanced outputs of a specialized headphone amplifier (such as the Sennheiser HDV 820) or a portable digital audio player. All the necessary cables are included in the standard package of the Sennheiser HD 660S. All cables are detachable, made of high-conductivity oxygen-free copper, and reinforced with durable Kevlar, which not only protects the cable from mechanical damage but also effectively safeguards the audio signal from so-called contact noise.

Listening to music on the Sennheiser HD 660S is always enjoyable. Their large elliptical cups comfortably envelop the ears. And thanks to the soft and dense detachable earpads, as well as the wide and thick headband cushion, the HD 660S are securely but delicately held on the head without excessive pressure.
