If you’ve ever been married or held prisoner in a dungeon, you are probably very familiar with the ball and chain concept. This is kinda like that, but for your iPod.

It’s a speaker that stands out by being an odd looking ball. ZumReed’s Sound Ball speaker is designed to hang out on your key chain or book bag, and when you want to hear some tunes, just plug it into the audio jack on your iPod or other mp3 player. Comes in pink, lime green and purple flavors and the battery is built-in and rechargeable via USB. It will get you some odd looks. Say, I wonder why they don’t come in pairs, that wouldn’t look weird at all.
