DESCRIPTION
SUPREME IN STYLE AND IN SOUND
The Sennheiser HD 660S has an eye catching new matte black and anthracite design. It looks classically elegant with some hints of contemporary influence. It is truly a symbol of sophistication.
LIGHT ON WEIGHT, HIGH ON COMFORT
With High Quality Sound, the HD 660S also gives you High Comfort. In spite of its strong build, this pair is very lightweight. The elliptical ear cups are shaped according to the anatomy of the ear and sit perfectly over your ears giving you superior comfort. With comfortable earpads and its open construction, you can listen to music on these for hours on the trot.
RICH, INTRICATE SOUND WITH WELL-DEFINED BASS
The HD 660S has exceeded its predecessor HD 650 in terms of the sound output. With a crisp and defined bass, clear mids and pleasantly natural treble, it offers an exceptional soundstage response. You hear every detail and expression of the songs you play that takes you on a completely different journey full of emotions altogether.
INNOVATIVE TRANSDUCER TECHNOLOGY
Built with the new Transducer Design, The HD 660S offers a much better performance as compared to the HD 650. It is engineered with a specially manufactured stainless steel fabric attached to the diaphragm that facilitates better control of the diaphragm movements. Moreover, 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.
EASE OF CONNECTIVITY
The HD 660S is much more versatile as it can deliver reference-class sound when connected to hi-res mobile players even with its lower impedance.
