Many a blustery, winter day I've walked around campus, attempting to listen to my walkman/discman/mp3 player while trying to cover my ears as well. Hats just don't do the trick, and it's about as dorky as it can be to be traipsing around with a ski cap pulled so far down on one's head. I propose that headphones be inserted into earmuffs... I had a rather large pair of head phones that I used AS ear-muffs, but this still wasn't as refined as the invention could be. Make 'em cute and there...
