Sennheiser RS 170 Wireless Headphones

Superb wireless headphone system for movie watching and music, the Sennheiser RS 170 Wireless Headphones employs a KLEER transmission scheme to provide quality noise-free audio that's also wire-free. The included RS 170 headphones have a 'sealed-back' earcup construction providing isolation from environmental noise while also preventing the person next to you from hearing headphone audio 'leakage' -- a big plus for keeping copacetic with the spouse or cubicle mate. The RS 170 wireless base station doubles as a charging station for the headphones, has an effective 'surround sound' feature for movies, and even a bass boost button that nicely bumps the bottom-end for a fuller sound.

What We Think:
Excellent for great movie and TV watching sans cables, the Sennheiser RS 170 wireless system not only sounds absolutely terrific, it also features 'Surround Sound' simulation and bass boost controls that actually deliver effective results. Our HeadRoom reviewers were overjoyed with the voice clarity and clean, smooth sonic performance of the RS 170 headphones, which are the result of advanced wireless research by the German engineering team at Sennheiser and the use of new KLEER signal transmission schemes for maximum clarity of wireless audio. Until very recently, wireless headphones have been plagued with noisy transmission that interferes with high-quality listening and intelligibility of speech and dialogue. Now Sennheiser has teamed with KLEER -- a third-party provider of CD-equivalent (16bit/44.1kHz) digital audio wireless technology -- to employ new microchips that deliver true 'high-definition' audio quality, have very low power consumption, allow for multiple headphones to be used from the same base [up to four headphones], and also automatically tune transmitter + receiver to the clearest available channel while avoiding localized RF interference. As a result, dialogue and speech come shining through loud & clear with better detail than the TV's own built-in speakers. The Sennheiser RS 170 Wireless Headphones system highly benefits from these proprietary advancements and makes it amongst our top staff recommendations for 'audiophile-level' wireless headphones.

The Sennheiser HDR-170 headphones included with the RS170 system are a 'sealed-back' / closed earcup construction so they'll provide some isolation from environmental noise as you enjoy your TV, movies, or music in peace; the sealed-back construction also prevents 'leakage' out from the headphones so that the person next to you on the sofa or in bed won't have to endure your audio -- a nice thing for the spouse or cubicle mate. Each earpiece accepts one [1] rechargeable AAA battery (included) and will run for about 24 hours per charge. Recharge time is long: 12 hours from completely empty to full. The Sennheiser RS 170 has a long walkabout range and can transmit up to amazing 260 feet via 2.4-2.8gHz, auto-selecting the clearest channel for best performance. Run-time is about 24 hours on each full charge. Additional wireless Sennheiser headphones may be purchased separately with up to four (4) headphones operating simultaneously from one wireless transmission base.
