Along the back of the Creative TravelDock 900, you'll find a few useful ports and features. On the far left is a universal USB adapter that lets you simultaneously play and charge an iPod Shuffle (if the speakers are plugged in to DC power). To the right are the auxiliary line input, the Wide Stereo Effect switch (more on this below), and the DC power jack. However, a power adapter is not included.
Like most entries in Creative's latest travel line, such as the, the TravelDock 900 features a stereo-expansion function--just flip the switch on the back of the unit, and all of a sudden, your stereo field seems wider. It's an illusion, of course--you're not going to get much stereo separation from speakers mere inches apart, but it works rather well, and it's the strongest feature this little guy has to offer.
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.
