One time I came into the city and went to OMG Shop (click on the name for the foursquare page) for a hot red one, they didn't have it - only pink, purple and green. I waited for another red, but I ended up getting the vampy purple one yesterday - A Vampy Purple X-mini™ II Capsule Speaker™.
I charged it about two-and-a-half-hour and it is booming. I'll try to get a video footage when Indra, Shirako and me connect our red, black and purple ones together and play some kick ass track to make them dance on their feet.
Low volume music NO MORE.
