Sennheiser launch HD 660 S headphones and IE 800 S in-ears

Sennheiser have dropped two new seriously high-end headphones on us, namely the HD 660 S over-ears and the IE 800 S in-ears. Both products are designed to appeal to the audiophile market. If you want either of these pieces of gear, you better have deep pockets. The HD 660 S will set you back $499.95 USD ($799.95 AUD), while the in-ears will come in at $999.95 USD ($1599.95 AU).

Update on hit open-back, over-ear design

The HD 660 S is an open-back over-ear headphone designed for use with high-end audio. The design is based off the HD 650, but Sennheiser say it surpasses it with an:

“improved transducer that delivers lower harmonic distortion for a more natural, lifelike audio experience.”

The lower impedance of 150 ohms enables the headphone to be used with stationary and mobile HiRes players. Sennheiser have included a hand-selected stainless steel fabric transducer adapted to the contour of the diaphragm, intended to provide consistently narrow (± 1 dB) tolerances.

The older HD 650 got rave reviews from critics and users so Sennheiser have their work cut out to improve on it. One point of criticism was the weight of the HD 650. This time Sennheiser state they’ve improved the comfort with a “robust yet lightweight construction.”

Connectivity won’t be an issue, as the headphones have the following detachable connecting cables: 6.35 mm stereo plug and a balanced 4.4 mm Pentaconn stereo plug. There’s also a 6.35 mm to 3.5 mm adapter provided. The large size of the headphones lends them much more to home use than anything else, which is presumably why we only get an adapter to 3.5mm.

The other release we got from Sennheiser is the IE 800 S, which is an update on the IE 800 in-ear headphones. This time the Germans have improved the acoustics with “brilliant trebles and a refined bass sound”, refreshed the look and included a wider choice of cables. In addition to the standard 3.5mm jack cable, the new version offers 4.4mm Pentaconn and 2.5mm balanced connectors.

The Extra Wide Band (XWB) driver has been updated, providing detailed, distortion-free audio. Comply eartips have also been included in the IE 800 S, which are made of ergonomically designed viscoelastic memory foam. They are intended to provide a “custom fit” to the ear canal for comfort and attenuation of ambient noise. Sounds swanky no?

Both products will be available from November.
