we buy two pair of these and they work reasonably well of the price . sound quality be so-so , noise-cancelling be good , but the piece of plastic that hold the headphone open -lrb- when unfold -rrb- be go to break . we also have both pair lose sound in one sound over time . we do not treat thing roughly or use they all that much . anyway , while they work they be a decent deal and if you figure you can have five pair of these for the same price as one of the bose it might be acceptable .
