The headphones are a great alternative to the rediculously overpriced Bose products. They do a pretty good job at quieting ambient noise. Probably nearly as good as the Bose. On the airplane, it would have been nicer if they were around the ear instead of on top of the ear. Better noise control. They are quite comfortable to wear long term. The cable supplied is too short. Works fine with an I-Pod or other "close at hand" device. But for general use, the cord is way too short. Over all though, good value.
