For such a small set of speakers the Creative TravelSoundi has quite a voice. We like the video-out and subwoofer additions, plus the ability to connect any iPod or other audio device. More so, the sound-widening is very impressive.

We prefer the design of Belkin's TuneBase model, but the TuneCast Auto is still a worthy option boasting reasonable sound quality and the convenience of ClearScan technology.

The iTrip Auto doesn't feature the flexible steel neck design of its RoadTrip counterpart, but its compatibility with the iPhone and the three-stage light ring indicator are attractive features.

The iH8 provides a fantastic combination clock radio and set of speakers for the iPod. There is little to fault iHome’s offering, though we would have liked to see slightly more integration with the iPod’s user interface.

The Bowers & Wilkins Zeppelin is an impressive but extremely expensive iPod speaker system.
