| The Bottom Line | Sennheiser's affordable, comfortable wireless headphones sound almost as good as corded 'phones. | 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 180's sound is competitive with similarly priced wired headphones, which should make the RS 180 irresistible to audiophiles seeking to cut the cord. | Basic specs | |
