Sound for enthusiasts
Top Sennheiser technology
The speaker designed by Sennheiser is the core of the HD 660 S. The movement of the diaphragm is greatly improved by the addition of a stainless steel foil on its contour. Lightweight aluminum voice coils ensure superior fidelity, and the speakers are individually tested and selected with a tolerance of ±1 dB.
Designed for comfort
All the details of these headphones are designed for listening pleasure; they are durable yet light enough to wear for long listening sessions. The cups are perfectly shaped to sit firmly over the ears, following their anatomical shape, the memory foam earpads are extremely comfortable, while the head cushions are soft and fit effortlessly.
The HD 660 S headphones have been designed to enjoy a variety of audio sources thanks to their low impedance. However, the full potential of these headphones is realized when using the balanced cable in a dedicated amplifier or portable player (DAP). SENNHEISER has included in the package quality OFC copper cables for every situation: with unbalanced 6.3mm jack, 4.4mm balanced and 6.3mm to 3.5mm adapter.
