answer: Sound is great and noise cancelling is excellent
paragraph_question: question: How good is the phone?, context: I tried on several of these headphones in the stores. They were the most comfortable I had ever worn.  Sound is great and noise cancelling is excellent but after wearing for 20-30 minutes they start to hurt my ears.  I do have big ears and they stick out from my head so I guess it is partially my fault.
