| Bottom line | The Sennheiser RS 180's sound is competitive with similarly priced wired headphones, which should make the RS 180 irresistible to audiophiles seeking to cut the cord. | 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. | The Sennheiser RS 220 is one of the best-sounding wireless headphones on the market, but its super sonics don't offset its ambitious price tag when other models in the same line offer similar performance for less. | While they're no bargain, the Bose QuietComfort 15s currently offer the best sound and silencing capabilities in a pair of noise-canceling headphones. | The Audio-Technica ATH-M50 Professional Studio Monitor Headphones are among the best available for less than $200, offering excellent sound and build quality. |
