how to make a 3rd party xbox 360 headest?

alright for all those computer wizards out there i want to make a headset from a apple iphone headset. obviously the apple headphones are a 3.5 mm jack and the xbox controller fits a 2.5 mm jack. which adatper do i need to buy for this to happen and work. thanks

heres the link for which one i need.

While I don't have an XBox 360, there are some standard conventions to follow. Male and Female plugs/jacks can be thought of as analogs to the human "privates". The end of the headset is a plug and is male. The jack on the XBox is female. So you would need a 2.5 mm plug (to plug into the XBox) to a 3.5 mm jack (for the headphones to plug into). I would also assume that the XBox and the headphones are stereo and you would need the stereo version (3 connections). The actual one you buy, plug adapter or corded adapter, is up to you, as long as you get the connections listed above.
