So i'm in the market for some headphones and want to hear everyones suggestions on what headphones would be best for the $300 range. I primarily listen to classic rock, hard rock, alternative, and trance. I'm looking for quality and comfort over anything. I've heard alot of good things about the Bose QC15's, as well as the B&W P5's. I'm looking for unbiased answers based on personal experiences, especially if you've used both of the headphones in question. Anyways, the question is: Which are better/higher quality for music? Bose QC15 or B&W P5?
