We all know the benefits to carrying around a boom box: blasting your music so all others must listen, intimidating others, being generally an obnoxious person. But what about the drawbacks? They include shoulder fatigue, arm fatigue, and being generally an obnoxious person.

This rollable MP3 boom box solves at least two of those drawbacks by allowing you to push your stereo around like a stroller. You than therefore force your musical tastes upon all the poor souls around you without having to switch shoulders every couple of blocks to help sooth your sore arms and shoulders. Everybody wins!
