I really enjoy these headphones. They aren't necessarily noise canceling but they definitely block out what my roommate is trying to tell me. One issue is that when they are playing loud music, people can hear it a bit but also you're not suppose to play music that loud anyway. I don't use the bluetooth function much (I prefer wires over having to charge items) and every time a sound was made there was a beep at the beginning and I'm not sure if that's my user error or the headphones but they are great for the price. I did think they were a little tight at the beginning, wearing them for a long time would start to hurt my head, but after a while it seemed the plastic started to give a little more and so its much more comfortable now.
