Photos: Top ten portable speaker systems

6. Altec Lansing InMotion iM4

Strengths: Excellent sound; portable music players fit nicely on the rubberised base; retractable minijack cord; speakers tilt at any angle; can be powered with batteries.

Weaknesses: No remote control; slightly large and heavy compared with other small speaker sets.

Conclusion: The Altec Lansing iM4 finally delivers the bass we've been craving in small portable speakers, and they're not iPod-centric, so you can use them with any MP3 player.
