I use these headphone both in airplane and in my health club . they do a good job of cancel most noise in either place . the sound quality be quite good , with no obvious deficiency . the headphone come with a nice set of accessory : a carry case , two 1\/8 '' -lrb- 3.5 mm -rrb- audio cable , one short , one long , a two-pin airline adaptor , and a 1\/4 '' -lrb- 6.3 mm -rrb- audio plug adaptor . they also come with a top quality AAA battery . I have buy four set of these phone , one for my wife , and three for I . -lrb- I lose one set ; another develop a problem . -rrb- the only problem I have have be with the foam rubber ear cup . they come apart after a few year use , probably because they get damp from my sweat while exercise . -lrb- this be why I give they only four star . -rrb- I also consider get the latest bose headphone , but could not justify they higher price . other review on Amazon suggest that the Audio Technica phone sound better anyway .
