JBL On Stage Micro II

Portable Loudspeaker Dock for iPod and iPhone Share your music library with friends anywhere your travels take you, indoors or out. On Stage Micro II measures just 6 inches (150mm) in diameter, and weighs in at only 0.67 pound (0.3kg). But with two JBL Odyssey full-range transducers, it has the muscle to outperform many much larger systems. Four AAA batteries deliver hours of continuous use, and with a USB cable, you can even sync and charge your iPod or iPhone with iTunes.
