Product Description

Sennheiser HD660S Headphones descend from the legendary HD 650 featuring improved performance with a new transducer design for sophisticated audiophile sound in a large range of listening situations.

Audiophile Versatility

Thanks to lower impedance, it delivers reference-class sound also when connected to hi-res mobile players, thus offering much greater versatility. The HD660S is an elegantly designed piece of high-quality engineering that indulges the demanding listener with aural precision and great wearing comfort.

Sound for the Passionate

Made for the demanding listener, the HD660S surpasses the exceptional performance of its predecessor, the HD 650. With a crisp bass, excellent mid-frequency response, and a gentle, pleasantly natural treble, the HD660S has an expressiveness that immerses you in every emotion and nuance of music while always staying exceptionally accurate and transparent.

Cutting-edge

The HD660S 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 aluminium voice coils ensure the highest impulse fidelity. The transducers are carefully selected and paired by hand to ensure consistently narrow (±1dB) tolerances.

Supreme Connectivity

The HD660S has been created to enjoy music in supreme quality and from many different audio sources. The low impedance also offers reference-class fidelity with hi-res mobile players.

Choice of Cables

Naturally, it reveals its full potential when 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 reinforcement.

High-end Comfort

Everything about the HD660S makes your listening experience 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.

Sophisticated Look

The pure and effortless sound of the HD660S is reflected in its new matt black and anthracite design. It is a high-end aesthetic that embraces both timeless elegance and contemporary style – uncompromising in its craftsmanship, like everything about the HD660S.
