iPod Mono-Strap Backpack
Don't you hate having to take off your backpack whenever you feel the need to change a song? or pause it? or turn it down? Now you don't have to.
"The HiJack is a very simple little device. It plugs into your headphone jack and splits it into two jacks. What makes the HiJack so sweet is it's tiny size and keychain clip, so you can keep it with you wherever you go."
I idea of something like these seem incredibly sci-fi or some half-witted attempt to be futuristic from 1987. But no, these are actually real and work and are pretty awesome.
