that an interesting idea :3 . but speakers are heavy, and you'll need extra wire if you expect to move around freely. The best type of speeker to use would maybe be, the ones that go in those 360 earmuff things. or dismantle some headphones. that one part is light but if you use something with a casing it will be heavy.
