The Jammypack is a must-have accessory for any eccentric mu- sic lover. The retro speaker bag features two mini-speakers, each boosting 3 watts of stereo-amplified beats. Powered by a USB con- nection to a AA battery box, this thing will jam for six to 10 hours at a time. It’s compatible with iPods, smart phones, and anything else with a headphone jack output. It wraps nice and snug around your waist and the electronic components zip off so you can throw the pack in the wash. It comes in many different colors and de- signs so you can find one that suits your style. And it’s even water resistant so you can rock by the pool. It’s not a fanny pack, it’s Jammypack.
