Bird Electron of Japan has released a new leaf-shaped leather key ring, but this one comes with an added feature – a built-in speaker as well as an audio jack, making it compatible with just about any digital audio player as long as they subscribe to the 3.5mm format. I’m not too sure why you would want such a tiny personal speaker in your pocket, since a pair of headphones is able to do a much better job, and it isn’t good enough to share music with others in a noisy room, either.
