I know this is a bit off-topic, but you *can* distinguish from a sound directly
in front and directly behind you. The pinna (those fleshy thingies most people
consider their ears, and punch lotsa holes in ;) modify the wavelength so that
the brain can determine where the sound comes from.

Do cyberears actually replace the pinna? In the description, it says that
they're an obvious prosthethis...how so? Can you get your cyberear pierced, if
it does replace the pinna, and can you get it so that it isn't so obvious?
