Someone should make headphones that are wireless and in the shape of hearing aids, you know, for those times when you want to be inconspicuously not bored as hell sitting in certain classrooms. I would pay a good $50 for a decent pair.

It can’t be too hard, just use bluetooth, RF or even FM. Sound quality isn’t a great concern given the alternative. Have some sort of rechargable battery thing that I can dump into a dock at night for the next morning. I wouldn’t be surprised if everyone in university will go slightly deaf overnight (I tell ya, it’s all the iPods) but will miracuously recover when they graduate.
