Wander around the house, and take your music with you. Run it on battery power or plug it in. Either way, the inMotion Max churns out lush sound from your iPhone or iPod, or from the unit's built-in FM radio. Twin, full-spectrum speakers give you the accurate sound reproduction and warm acoustics you crave. XDB technology supplies the deep bass without a subwoofer. And ESS sound-widening technology expands the sound to fit any room. What's more, when somebody calls your iPhone, the music pauses so you can take the call.
