Mobility is encouraged via the iM7?s long lasting battery mode. Or plug into a nearby outlet for AC power. The iPod recharges while you listen. Your dockable iPod is secured within a patent pending universal cradle that gracefully opens and recesses with the touch of a finger. The iM7?s impressive sound comes from highly advanced neodymium drivers and tweeters, plus a powerful, built-in subwoofer. A wireless remote provides across-the-room command of both the iM7 and iPod, allowing perfect adjustment of your music.
