Query: Good sound for the price, comfort is questionable though.

The sound quality is commendable. The high and mids are crisp, clear and well defined. It is a little lacking in the bass though. My greatest complaint is in the comfort for longevity. These headphones are extremely tight. Im 6'4" tall and 230lb. I do not have an abnormally large head. These headphones fit very snugly. After about 2 hours they begin to get uncomfortable to a point where you are repositioning them on your head. The pressure around your ears is where the discomfort is greatest. The sound isolation is absolutely excellent though. I have a very loud air cooled PC right next to me and it is completely deadened by these phones. If you are larger than average, like me, perhaps consider another brand/model. I have worn these for about 2-3 weeks and have yet to experience a stretching out, or easing of tightness like I have read will happen.
