The UWaterG2 is a new MP3 player that is likely the smallest one you�ve ever seen. Boasting a tiny 0.9x3x4.5 centimeter body, this is likely the world�s smallest MP3 ever. Well, one that is waterproof anyway. A twist and lock earphone jack makes sure that water stays out, along with corrosion that might normally damage other devices with a regular jack.

It can hold about 2 GB, which is about 500-600 songs or 5 audio books and has a 6 to 8 hour battery life. It doesn�t even weigh an ounce and will set you back around $60. A big concern with something this small is that you might lose it. Especially as it�s design is meant to be used underwater. This fear is somewhat eased as it has a highly visible LED light option, and comes in some rather bright colors.
