This portable slim, powerful Bose SoundDock digital music system allows you to play your iPod anywhere with acclaimed Bose sound because it has a rechargeable lithium-ion battery that provides up to three hours of operation at full volume before requiring a recharge. With a built-in handle, the unit's stereo speakers produce vibrant, concert-quality sound when any iPod with a dock connector is placed on the dock, and the system comes with a remote control to manage basic iPod functions without leaving your chair. Active electronic equalization fine-tunes the output of all sound frequencies for natural tone balancing and clarity, and the patented integrated signal processing fills the room with rich, lifelike performance no matter the volume. The space-saving SoundDock also charges your iPod, whether in use or turned off, and the shielded speakers allow you to place the unit near televisions or computers without interference. Battery requires ten hours for a full recharge. Plugs into AC. 6 5/8" H x 11 7/8" W x 6 1/2" D. (4 1/2 lbs.)
