If there can be any miniature model of an already tiny MP3 player, it has to be the Micro Sport Japanese MP3 player. The entire device is hardly a size of an ear plug, yet incredibly full-functional. Even on the audio quality front, Micro Sport offers full stereo sound, and you can pack upto 4GB of mp3 songs into this dimunitive device. The main unit also has an attached earbud for one ear, while the other has to be connected with the given suspension cord. You can connect it to your computer via USB port for an easy transfer of music. The amazingly tiny marvel retails for $79.9 at ThinkGeek.
