Spyder offers the sweet Groove Backpack with stealth NXT sound. This looker of a bag is powered by 3x AAA batteries. This will give the bag up to 7 hrs of beats. Connectivity is simple with a standard 3.5 mm jack.

Cavernous at 25L of volume, at a sticker price of $119.95, this is a compelling buy. But at a rumored $69.00 it is a steal. Go ahead, go get one.
