These Macally speakers are shaped like a frisbee with a box behind it that contains the batteries. The IP-N111 comes in both white and black to match your color Nano, and are powered by three AAs that last up to 12 hours—about as long as your Nano. The 500mW power output is good for taking your music on the road, in the bathroom, in prison, and in a coffin when you're being buried alive.

Available now for $39.99.
