As others said, the ear pads look pretty big haha but you get used to it. Never had a problem with the mute button getting pressed or anything. Very convenient and much better than taking off a glove and taking out your iPod to mute it to talk!
This thing is so amazing its ridiculous. Only 2 buttons which makes it so easy to use, you don't need to be a master with a camera. Best quality ever and so small you can store it easily or wear it and get some amazing shots. I think all three editions are worth there price.
