treble, the HD 660 S has an expressiveness that immerses you in every emotion
and nuance of music. Still, it always stays exceptionally accurate and transparent.

Sennheiser technology

The HD 660 S features a new transducer design developed by
Sennheiser. This results in improved control of the diaphragm movements thanks
to a specially manufactured precision stainless steel fabric, which is adapted
to the contour of the diaphragm. Extremely light aluminum voice coils ensure
the highest impulse fidelity. The transducers are carefully selected and paired
by hand to ensure consistently narrow (±1 dB) tolerances.

Supreme connectivity

The HD 660 S has been created to enjoy music in supreme
quality and from many different audio sources. Thanks to its low impedance it
also offers reference-class fidelity with hi-res mobile players. Naturally, the
HD 660 S reveals its full potential when it is connected to the balanced
outputs of a dedicated headphone amplifier such as the HDV 820 or to the
balanced output of a mobile digital audio player. Accordingly, it comes with a
choice of cables for just about any occasion. All cables are made of highly
conductive OFC copper, featuring very low handling noise and sturdy para-aramid

Designed for high-end

Everything about the HD 660 S makes listening a pure
pleasure – not least its strong yet lightweight open construction. The
elliptical ear cups are shaped to follow the anatomy of the ear, while thick
padding on the headband and the replaceable ear cushions guarantee hours and
hours of listening in supreme comfort.
