The uBoom (pictured below) is a beast at 3kg, and its 24 watt sound (total RMS) does need a power supply. The 400g uBoom Q (2.4 watts) is USB powered. Both have an auxillary audio input, and the uBoom adds a microphone jack.
The speakers just went up on Asus’ site for you to check out, but there’s no pricing info yet. [Asus]
