Imagine wearing them, watching a tv show on your ipad. When you turn your head, it still seems like the sound is coming from the direction of your ipad. Also used for surround sound, so if you turn your head, the "center channel" still is focused on the screen, and surround sound is where it would be if there were actual speakers behind you.
