Soundwave runs on a single AAA battery, lasting for about six hours of continuous play, and operates using a miniSD card; the packaging claims it can only support up to 1GB, but reports indicate it can actually take up to 2GB.
Its tempremental, it point blank would not work with the first few SD cards I used in it. In fact I returned the first one I had because it appeared to be broken. By dumb luck with the replacement I quickly tried a card that it liked otherwise I would have sent that one back to more than likely.
It played fine, but you only had play pause and skip tracks. And it would just play whatever was on the card in one order if I recall correctly.
