Why does the GH3 controller PS3 have a Phone Jack?

May be...

maybe its for headsets, i havent really looked at the controller much, but for 360, the headsets just plug right into the controllers, i havent been on my ps3 in a while



just google it or look at the books that come with guitar hero

i dont know either. its kind of wierd, isnt it?

for online play i guess, but i dont think you can use it for anything yet
