I actually thought these were going to be good. When I tried them on at the apple store I was impressed by the comfort. They were out of power so I didn't get to test the sound or noise cancelling. I got a pair and was happy with them until I tried a pair of ATH M50.It was then that I realised just how bad they were in terms of sound quality. What's more, they attract so much attention that you feel embarrassed using them outside. To top things of, the left ear cup broke within the first month!
I actually thought beats could improve. But now I doubt they ever will.
