A guy at work just bought one of these. We connected it to an iPhone via bluetooth and have been having a mini rave in the office today.
It's only 15cm long and 4cm high but the sound is brilliant. The clarity is unbelievable for something so small and easily fills a big room.
Its pricey at about £150 but for the size, sound and convenience its unbeatable.

I've seen these in the flesh and they do sound good. Nice bass the them as well. They sell them in Costco for a bit cheaper (Can't remember how much but wasn't £150)
