Sonic Impact Boom Bag

Summary: amazing sound!
Review: Since I'm the first to write about this product, I'll try to give a good description. This backpack is amazing. The speakers are actual speakers that you can take out of the backpack and use. There is actually bass, which I thought there wouldn't be ( there isn't that much, so it works best with anything with an extra bass equalizer). The backpack in general is just a daily commute kind of backpack, with decent space. I have no idea why it can be found under mp3 player, oh, and it runs of 4 AAAs (the description doesn't include that). All in all, a great backpack for a great price.
