They are so awesome! I was really sceptical, and apparently Mum was, too, but my Dad had been super-insistent on them and was very proud of himself for finding them, and then I plugged them in and stared at them with a stupid grin on my face for about five minutes straight. There's something about the speakers moving to the music that makes the music seem more awesome, because it swells with the music swelling. It appeals to my synesthesia, maybe.
