the overall performance -lrb- sound quality , bass , etc. -rrb- exceed my expectation . no disrespect to Sony , but I always assume bose provide a better product -lrb- especially at the $ 100 price point -rrb- . these headset prove I wrong . one big note for air traveler - very nice surprise be the noise cancel capability . grant not complete like the over the ear noise cancel headset , but very sufficient for a in the ear bud .
