| The 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. | Though the ultra-affordable Sennheiser HD 201 headphones provide natural sound and capable performance, commuters may find the low volume output an issue when listening to music in highly trafficked environments. | Sennheiser's affordable, comfortable wireless headphones sound almost as good as corded 'phones. | Basic specs | |
