The company Brando has just released a USB key that has space for an SD or MMC card. Not only that, but it comes with headphones, and can be used to play back the music found on the SD/MMC card. There is a AAA battery that fits snuggly at the back, while the memory card is inserted in the front of the translucent unit.
The USB key at the front is USB 2.0 compliant, and the MP3 player last for 10 hours on one AAA battery. At this time the only audio format that is playable on the unit is MP3, although the unit can be used with both Windows and Macintosh. You can buy one for $15 over at Brando’s Website.
