The Good The Sennheiser RS 170 is a full-size set of headphones with Kleer wireless technology that delivers CD-quality sound.
The Bad The awkward placement of the controls on the right earcup may require a longer learning curve for some users, and the transmitter/charger base lacks digital inputs.
The Bottom Line The RS 170 continues Sennheiser's unchanging dedication to sonic clarity and they're well worth the price for anyone looking to grab wireless sound from a TV, AV receiver, cable box, or game console.
Sennheiser RS 170
The $279.95 Sennheiser RS 170 is a set of wireless headphones with a base unit that doubles as a transmitter and a battery charger. One of the nicest things a reviewer can say about wireless headphones is that they don't sound like wireless headphones, and the RS 170 certainly succeeds on that score. Connectivity is limited to just one analog input, which might be a deal breaker for some potential buyers, but the idea is that you hook up the transmitter to your TV or AV receiver, and then run your sources, like your cable box, Blu-ray player, or games, etc., through the TV or receiver. If that's what you're looking to do, the RS 170 is definitely worthy of your consideration.
Design and features
The RS 170 weighs just 216 grams without batteries thanks to its plastic construction. The satin black-and-silver headphones' build quality feels sturdy enough aside from where the earcups attach to the headband. There seems to be a bit of play in the joint that may cause problems with breakage over the long term.
The plush, padded headband and user-replaceable faux-leather earpads feel luxurious, and their oval shape conforms better to ears than the circular earpads used by competing headphone manufacturers.
