Bluetooth speakers are so common now that you can find them almost anywhere, and for pretty cheap. If you prefer a more quality audio experience though you'll want to go for something a little more high-end. This deal for the Jawbone Jambox on eBay is a perfect example of a great Bluetooth speaker which puts out some awesome sound but without the cost of the device at full retail.

Charging the speaker back up is capable via the USB port, and it also supports stereo input through the 3.5mm port if you wish to use it. You can grab the Jawbone Jambox on eBay for $54.99.
