The AMP Pocket Backpack is hugely entertaining as it offers built-in speakers and cell phone attachments that enable you to listen to your favorite tunes while answering incoming calls without actually opening up the bag itself. The music controls are placed on the shoulder strap; hence there is no need to strain your back for navigating through the play list. The AMP Pocket Backpack is powered by 4 AA batteries and is available for $130 from Smart Home.
