Cardboard headphones has cotton ball speakers

So, you are extremely envious of the different kinds of high end headphones that your friends happen to own, and they tend to brag about the hundreds of dollars that they have invested in a great sounding pair of cans. Well, here is a far cheaper pair that is also a DIY project, where it is made out of two prepared dc-motors, cotton balls, and the help of some cardboard boxes. These will not play “music” per se, but the pair of motors will make the cotton balls vibrate into the box, hence resulting in an effect that sounds similar to how one would play drums on your head. Not too sure as to whether this is cool or crazy though. What do you think?
