iPod Nano’s and Shuffle’s come in a hard plastic protective case. Most people will simple throw away the case, since it’s quite a bit larger than the players and not particularly conducive to storage. With this kit from Japan’s Bird Electron you can put that plastic case to good use by turning it into a speaker. It’s basically a replacement for one half of the clamshell casing, so instead of a lid, you have a speaker. The case is still open and can be used to store your earbuds and player when not in use.
