The Sennheiser RS 170 is the step-down version of the highly rated RS 180 (Est. $330) . Both headphones use Sennheiser's 2.4 GHz Kleer wireless technology for fewer issues with interference from other devices than wireless headphones from other makers. Sound quality is excellent, although perhaps a step behind the RS 180. The closed-back design isn't as well-liked by audiophiles, but it does cut down on sound leakage.
Great sound quality. The Sennheiser RS 170 wireless headphone features a closed-back design that's frowned upon by many audiophiles, but experts find that it still delivers a clear, balanced performance. Reviews say the RS 170 really shines when watching movies, where the closed-back design can be a plus as it cuts down on sound leakage. Sennheiser's wireless technology is more effective in combating interference and hiss. The specified transmission range is impressive, but real-world range where things like walls can get in the way is less so.
A good choice for the long haul. Stuart Andrews at TrustedReviews.com calls the RS 170 a "solidly constructed, well-designed and comfortable set of cans that you can use for hours at a time without irritation." He highlights the sturdy build and extra padding, saying this headphone fits well without putting your skull in a "migraine-inducing death grip." Other critics and users also commend the RS 170 for its comfort during extended use, but some call the volume control design and location a minor flaw.
Save a little, still get a lot. While the RS 170 is only $80 cheaper than the Sennheiser RS 180 -- and lacks some of its features like a well-regarded automatic level control -- it delivers comparable performance for the money. The RS 170 is even the go-to choice for some, especially those concerned about sound leakage in quiet settings.
Guttenberg likes the RS 170's performance. "They're very good-sounding, closed-back headphones, period," he says, adding that it's right up there with wired headphones in terms of sound quality.
