The noise canceling feature is great at the office when I want to cancel out the ambient noise.

instrumental, acoustic, and quieter music in general sounds awful because the ambient noise leaks through so badly

The headphones produce ambient noise to try to counteract outside noise (which doesn't do the job very well in the first place), but the white noise really interferes with the music you're listening to

Sound pretty good and cancels out ambient noise well, but uncomfortable to wear for extended periods (2+hours)

They did a slightly better job of reducing ambient noise than the AT's, although the white noise they use to do this is a bad choice

The price is, as you can see, too expensive to be bought when you aren't using it often

Bass is hard hitting, but not as annoying as in the QC15

And the mods and highs were not nearly as crisp as you should have from a pair of $300 headphones

They do not perform nearly as well as at least two other over the ear headphones that I have owned.

It doesn't bother me as I can hear it only when there is no music or video playing

Great i like
