Sennheiser RS 170
Superb wireless headphone system for movie watching and music, the Sennheiser RS 170 employs a KLEER digital 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.

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 digital 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 RS170 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  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 120 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. A free 2-year manufacturer's warranty is provided by Sennheiser on all their headphone products only when purchased from true 'Sennheiser-authorized' dealers -- like us here at HeadRoom since 1992.

Pros: high quality sound, good transmitter range, highly reliable reception
My wife and both use wireless headphones and own several made by Sennheiser, JVC, Phillips, Koss, and other brands. The RS-160 headphones utilize a superior digitized RF signal, providing good sound quality and unsurpassed transmission range and signal reliability. These RS-170 headphones are not quite the sonic equal of my ATH-M-50 or AKG K-240 headphones, but considering you are paying for the transmitter, the receiver, and battery charging circuits, and the extra hardware associated therewith, the sound quality measures up to the cost.
They are the sonic equal of the less costly RS-160 headphones (which we also own), but have a greater transmitting range and include additional features such as surround sound, selectable enhanced bass circuitry, and a convenient recharging stand. I think the charging stand and greater transmission range justify springing for this slightly more expensive model.
These wireless headphones sound clear, bright, and fairly well balanced across the audible frequency spectrum, and are a obvious improvement over previous Sennheiser wireless headphones.
One very cool feature is the RS-170 headphones work with the RS-160 and RS-180 transmitters, and vice versa. This means you can buy multiple sets and activate more than one sound source for all headphones. My wife and I leave one transmitter on the stereo system for music, and another on the computer to listen to old time radio programs streaming audio on the internet. That obviates moving the transmitter between sound sources whenever one wants to change sound sources. Very cool, indeed. (You can do this with older Sennheiser headphones, also.)
The most important advantage is the superior transmission range and signal reliability compared to any other headphones we have tried. Our other wireless headphones all use 900MHz RF (radio frequency) signals, and suffer from much shorter effective transmitter range, and are plagued by aggravating drop-outs and annoying hiss from RF/EM interference as we move about the premises. These headphones use a digitized RF signal and have a far greater transmission range, with far greater resistance to signal drop-outs and are free from RFI and EMI (i.e., radio frequency and electromagnetic interference.) Now, we roam all over the house while listening to our favorite music and radio programs. The RS-170 transmitter covers the while house (a 40x60 foot two story home) with no problems.
Bravo ! - While these wireless headphones are a bit pricey compared to the alternatives - they are well worth it, and the price is quite reasonable considering the improved performance they provide. I have finally ended my long search for good sounding, highly reliable, consistent wireless headphones.
That is MY take, anyway.... James R in Michigan.

The only small gripe would be more user friendly buttons on the headphones.
