Forget your headphones and start listening to your tunes outside the box with the PodBlaster ™ Stereo Travel Bag. It works with any Nano™, Mini™ or Ipod™ in a specially designed inner compartment that allows you to easily control these devices through a specially formulated membrane that protects your device from dirt, water and shock. You can also connect your MP3, PSP™, Satellite Radio or CD player. All cables to your device are included in self contained compartments inside the bag, and allow you additional storage for anything else you may need while traveling. The 3-watt water-resistant speakers are driven by an amplifier that is powered by 4 AA batteries (not included), which will provide you with many hours of music pleasure
