Summary: I bought these speakers about 8 months ago and they've proved to be very useful. The sound quality is very impressive given the size, and they fold up nicely for taking on trips. I found the battery life pretty good - they lasted a 3 week trip in Japan for me. It was a bit annoying that it didn't come with a power adapter, but I looked through my box of discarded wires and plugs and found a 5V adapter for an old USB hub.
Summary: These are great: lovely sound, good size, brilliant design and they look brilliant with my new new zen stone plus. I'd have given them five stars but the price has gone up a bit since I bought mine.
Summary: Another brilliant product from Creative. This is great for travelling. Overall a good quality sound that fills a room, no problem - the wide sound is an excellent feature. It is disappointing that the Traveldock 900 does not come with a DC power supply adaptor - trying to find someone that stocks one is driving me nuts! - had it done so I would have awarded 5 stars.
