Bose is known throughout the world for it's innovations in sound, from home theater systems to car speakers. They also offer reliable solutions for listening to your iPod without headphones. The SoundDock Portable is an iPod speaker system that reproduces your favorite music with fullness and clarity in a design even slimmer than Bose's original concept. Proprietary Bose technologies, including waveguide speaker technology, let you enjoy your iPod out loud in more locations without compromising sound quality. The SoundDock Portable's rotating dock disappears for storage and protection during transit and a molded handle makes it easy to carry the system from place to place. Once you've reached your destination, just dock and play your compatible iPod. The iPod charges as it plays through the speakers for uninterrupted music enjoyment, and the included rechargeable lithium-ion battery provides more power and longer playing time than most other rechargeable batteries. A custom remote easily controls the system and basic iPod functions. Auxiliary input lets you play other portable sources, too.
