The new Sennheiser HD 660 S allows you to enjoy sophisticated audiophile sound in even more listening variations. The successor of the legendary HD 650 excels with the improved performance of its new transducer design. Due to its lower impedance, it provides reference-class sound also when connected to hi-res mobile players, thus offering much greater versatility. The HD 660 S is an elegantly designed piece of high-quality engineering that indulges the demanding listener with aural precision and great wearing comfort.
Designed for the Passionate Music Lover
Built for the demanding listener, the HD 660 S exceeds the exceptional performance of its predecessor, the legendary HD 650. With crisp bass, excellent mid-frequency response, and a gentle, pleasantly natural treble, the HD 660 S has an expressiveness that immerses you in every emotion and nuance of music.
State-of-the-art Sennheiser Technology
The HD 660 S features a new transducer design developed by Sennheiser. This provides a improved control of the diaphragm movements thanks to a specially manufactured precision stainless steel fabric, which is fitted 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.
Superior Connectivity
The HD 660 S has been designed to enjoy music in supreme quality and from all types of audio sources. Courtesy of its low impedance it also offers reference-class fidelity with hi-res mobile players. Naturally, the HD 660 S releases 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 situation, which are made of highly conductive OFC copper, featuring very low handling noise and sturdy para-aramid reinforcement.
High-end comfort with a sophisticated look
The lightweight open construction of the HD660 makes listetning an absolute pleasure. The elliptical ear cups are shaped to follow the anatomy of the ear, while thick padding on the headband and the replaceable ear cushions provide hours and hours of listening in ultimate comfort. Its new matte black and anthracite design boasts a high-end aesthetic that embraces both timeless elegance and contemporary style, uncompromising in its craftsmanship, like everything about the HD 660 S.
