If electronic devices can’t be small enough for you, check out the Micro Sport Japanese MP3 player from ThinkGeek. The mp3 player is about the size of two sugar cubes, and it looks like a Bluetooth earbud. It connects to your computer (running any operating system – requires no drivers) via a USB cable, and you just drag-and-drop your mp3 files to the player. It has 4 GB of storage space and a rechargeable battery! It offers full stereo sound; one earbud is attached to the player, and the second earbud plugs in with a short cord that hangs behind your head. It’s imported from Japan by ThinkGeek, so you’ll need to go there for some English instructions. It’ll cost you $79.99 for the privilege of saying “mine’s smallest!”
