Tried it on today, very conformable and the noise cancelling is impressive during the demo. It has 3 levels of ANC, and you can double tap either ear/headphone and it will disable the ANC so you can hear like normal. Didn't feel like anything was on my head. On the 320 since its not too loud I'll stick to company headset but if I'm on anything louder (73) in the future I'll definitely get one.
