Product Overview
The inMotion iM500 powered speaker system from Altec Lansing is sleek, compact, and amazingly thin — much like the iPod Nano it's designed for. Although only 3/4" thick — about the width of three pencils — the system delivers a clean sound with surprisingly full bass. When connected to AC power, the iM500 automatically recharges your iPod Nano. And you can plug the system into your computer with an optional USB cable and sync your player while its docked. With six "AAA" batteries (not included), the iM500 can deliver up to eight hours of continuous play. The system folds flat for travel, and comes with its own soft carry case.
