Fu-bi of Japan has dropped this Retro Cube Mini Speaker with MP3 Player. It’s just like it sounds, a retro 3W x 2-channel speaker with built-in MP3 playback capability. It allows you to hook it up to your ipod or PC via USB 2.0.
The internal battery provides up to 3 hours of audio, and you can also play music directly from an SD/SDHC memory card. It’s available in Japan now for $50. We have no idea if it will show up elsewhere.
