These headphones are fantastic! The sound quality is crisp and clear, with deep bass that doesn't overpower the mids and highs. I was especially impressed with the noise cancellation feature, which blocks out most ambient noise even in loud environments.

The comfort level is exceptional - I've worn these for 6+ hour flights without any discomfort. The ear cups are soft and don't put too much pressure on your ears. Battery life is as advertised, lasting me about 28-30 hours of continuous use.

The sound quality is pretty good for the price point. The bass is strong and the highs are clear. However, I'm disappointed with the battery life. It's advertised as 30 hours, but I'm only getting about 20-22 hours, even at moderate volume levels.

The noise cancellation works well for constant noise like airplane engines or air conditioners, but doesn't do much for voices or sudden noises. The ear cups are comfortable, but they do get a bit warm after a couple hours of use.
