Input:
I have had these for almost two years and I have found that they do not hold up well.  The padding in the ears has flattened totally making them very uncomfortable.  The headphone cord has become stiff so that I have to bend it away from my face.  The biggest problem that has developed is creakyness.  The headphones creak anytime you move.  The creaking is loud and unpleasant and resonates inside the headphones.  If you are trying to wear them while sleeping on a plane the creaking sound is very disturbing.

The noise cancelling is good on a plane and the sound is good considering the price.  However I would not buy them again because they have aged poorly.
