If these headphones were $50 they might be something to rave about. The sound quality is decent and the noise cancellation works.These headphones are extremely uncomfortable to wear. I wouldn't expect to use them on long flights. The comfort of noise cancellation is very much outweighed the discomfort of having them on. However, my wife found them much more comfortable than I. If you have a larger hat size you might want to try something else.The design and materials are flawed for a product so spendy. After a bit less than a years use by my wife the on/off switch wore out. She might have used the switch as many as 3 times a day. I'd guess she used the switch maybe 1000 times at the outside before it wore out. Also one of the swivels attaching the phone to the head strap broke after only a years use.If you contemplate getting service on your headphones from Bose, even if you are willing to pay for it -- forget it.
