emotionally charged voice
Designed for demanding listeners, the HD 660 S features crisp bass, excellent midrange response, and mild, natural treble despite everything. The sound is accurate and clear, allowing you to immerse yourself in the emotion and details of the music.

Advanced Sennheiser technology
HD 660 S uses Sennheiser's new driver, which uses a specially made stainless steel mesh to help stabilize the diaphragm operation and adapt to the shape of the diaphragm. Lightweight aluminum voice coil delivers high accuracy. Units are carefully selected and hand-paired to consistently narrow errors (±1dB).

Replaceable cable design
HD 660 S is specially designed for enjoying high-quality music and matching different sound sources. The low impedance provides high reproduction for streaming high-definition music players. The HD 660 S can reach its full potential when connected to a dedicated headphone amplifier (such as the HDV 820) or the balanced output of a portable music player. Designed to be interchangeable, the headphone cables are made of highly conductive OFC copper and come with a 6.35mm plug headphone cable, a 4.4mm Pentaconn plug headphone cable, and a 6.35mm to 3.5mm stereo conversion plug.

Designed for comfort
The HD 660 S features a sturdy yet lightweight open-back construction with an elegant black body. The oval earcups are shaped to conform to the ear's structure, while the thick padding on the headband and replaceable ear pads provide hours of comfort. Listen and enjoy.
