Groupon currently has this really awesome looking Bluetooth speaker for just $39.99. They've got some nice color choices available as well. It has a built in microphone, and has a big enough battery to recharge your smartphone, which is always really nice to have.
"Unsightly and easily tangled wires are a thing of the past thanks to this Bluetooth speaker, which wirelessly plays music files stored on iPods, computers, and other mobile devices. Despite its compact size, the speaker can still suffuse rooms with sound that's as rich and full as a billionaire after a trip to the all-you-can-eat buffet. The built-in power pack also makes it handy when you're on the go, since it can charge your mobile devices through a USB port."
