Editor's note: Headphones: those magical things that give us the ability to create our own private world even while trapped on a crowded subway. We put them right up there with water and food on our list of life's necessities. And we love our Headphones wallpaper collection, which is basically an homage to one of the great inventions of the modern world. Yes, the internal combustion engine and sliced bread are great, too, but get yourself a chill Headphones wallpaper in the meantime.
