Headphone are comfortable. Noise canceling is superb. Audio is great if you don't need a lot of bass. Great battery life and access. Circuit bypass to listen without noise canceling. My two biggest deal breakers were this: The headband is not arched enough at the extension point. What I mean by this is that when you extend them they get wider not taller. Thus you look like you have a big hoop on your head. Impossible to relax your head. Second. The noise leakage is awful. The people around you can hear your audio as well as you can. No joke. I can hear the music with my wife wearing them in our very loud Ford Diesel going down and exposed aggregate highway with the volume turned up to less than half. This is worse than any headphone I have even listed to. Fix these two easy problems and you have a top notch set of headphones.
