Elecom’s new “MS-77U” USB speakers must have taken a cue from the MobiBLU, but that’s fine by us. Measuring only 51mm (2-inch) in every direction, the speakers manage to output 2 channels at 0.5W each, and are powered from your USB port. Although they suffer from the tired blue LED gimmick, Elecom at least did something interesting; they put the LED on the bottom of the speakers, so they may look nice sitting on your desk. They’ve already been released in Japan at 4,410 yen (~$38 USD).
