HEROE Audio Technology has come out with a set of MP3 speakers that you can theoretically hang from the back of a backpack. "Carry the music wherever you go," their ad says. Can't we already do that thanks to MP3 players?

Oh wait, these are speakers for an iPod or other MP3 player. These speakers put out a whole watt and a half of power and are powered by 3 AAA batteries. So not only can you take your music with you, you can make everyone else hear it as well.

I'm thinking this will show up on Woot any day now for $0.99.
