Jansport, one of the most popular backpack manufacturers in the world, has a line of Livewire bags designed with portable audio in mind. Their Livewire bags each have a universal headphone port mounted on to the shoulder strap with an internal connection cord that is compatible with any mp3 or cd player. Inside the bags, a special protective V-loft pocket safely stores your mp3 player inside the pack. Their Livewire+ bags go a step further by having a soft-fabric keypad integrated into the shoulder strap so that you can have full remote control of your ipod on-the-go. Finally, their LivewireBT is even more suped up then the Livewire+ bag because its soft-fabric keypad can control both your ipod and bluetooth phone. Also, its backpack strap has a built in microphone for hands-free use with your headphones.
The Livewire series comes in several designs and several colors. Trinity and the Audio Pack, two of the Livewire+ bags, are even available in pink.
