The performance was a nice surprise. Though the TravelDock 900's drivers are identical to most of those in the Creative line, there are only two of them, and the likelihood that they could handle high audio levels seemed low. Sure enough, distortion occurred at superhigh volume levels; however, at reasonable levels, these speakers sounded just about as good or better than anything in their $80 price range. Plus, the rated battery life of 32 hours from the four included AAA batteries is nothing to frown at. The Creative TravelDock 900 won't knock your socks off, but it may be the choice for folks looking for the easiest way to connect their flash-based MP3 players to portable speakers.
