Sennheiser’s launches Hd 660 S Headphones for THE home studio
Sennheiser has launched a new open dynamic headphone for the passionate audiophile – the
HD 660 S. The new model builds on the legacy of the HD 650 and features a new and
improved transducer design that delivers lower harmonic distortion for an even more
natural, lifelike audio experience, the company says. With a lower impedance of 150 ohms,
the HD 660 S offers even greater versatility, allowing listeners to enjoy the headphones’
reference-class fidelity with both stationary and mobile HiRes players.
It’s improved acoustic design ensures low harmonic distortion, while Sennheiser’s
proprietary transducer offers improved control of the diaphragm movements thanks to
a specially manufactured precision stainless steel fabric, which is adapted to the
contour of the diaphragm. The transducers are carefully selected and paired by hand
to guarantee consistently narrow tolerances (±1dB), while their extremely light
aluminum voice coils ensure the highest impulse fidelity.
In the HD 660 S, leading-edge technology meets a long tradition of uncompromising German
audio and builds quality, Sennheiser states. This combination of craftsmanship and
breakthrough innovation is reflected in their new matte black and anthracite design – a
high-end aesthetic approach that embraces both contemporary style and timeless elegance.
The robust yet lightweight construction also makes listening supremely comfortable. The
elliptical ear cups are shaped to follow the anatomy of the ear, while thick padding on
the headband and the replaceable ear cushions provides a relaxing and luxurious
experience that places the enjoyment of music at center stage.
Offering a lower impedance of 150 ohms, the HD 660 S can be enjoyed with HiRes mobile
players or when directly connected to high-quality, stationary HiFi components.
Sennheiser recommends the use of dedicated amplifiers, which offer balanced outputs
such as the Sennheiser HDV 820 or the balanced output of a mobile digital audio player,
if available. Accordingly, the headphones offer a choice of connectivity options. The
detachable connecting cables made from highly conductive OFC copper offer either a
6.35 mm stereo plug or a balanced 4.4 mm Pentaconn stereo plug, with a 6.35 mm to 3.5 mm
adapter also provided.
