My friend has a sinple solution for headsets without buying expensive ones, With this you can just buy the chaep ones

First of all, you need these things

Not so sure if it's called that(it's what it says on the box that time) but It looks like this

It's Basically the AV Cable Without the V(video) that converts to a 3.5mm Audio.

Then you need an AV Selector. Looks like this

Now you plug the FM Cable to the AV Selector like so. And then PLUG the 3.5mm Input of your headset to the Output from the FM Cable. http://img684.imageshack.us/i/26062010083.jpg/

Then you plug the Red and White cables from your ps3 to the other side of the Selector like so

and it should be working by now. make sure you put the output of the audio to the AV cables. It's under audio settings in the ps3.
So the main idea here is to output your ps3 audio to the headset.

and if you want a mic to work. you can buy a USB Soundcard like this

These are good if you want to hear footsteps in MW2 I use Siberia V2 Headsets by steelseries

@De_lasoul

These are the three best in my opinion

The bank for buck Headset would be the px21s by turtle beach, even though it is stereo only but it is still good enough for COD and other FPS, Still can hear footsteps 75.95 USD

The second one is the Tritton ax720, 5.1 Digital Sorround but the AX720 Requires a power supply of 120V i think for their Decoder or Mixer. 130 USD

The third option would be the beast and most expensive option, The Astro A40s, My friend has one of these and Daym! Its a really good headet 5.1 Sorround 200+ USD

This is just my view of the 3 headsets that would be best for FPS games

and Actually The sound does not go via USB that is just for the Chat, The sound either comes from Optical Cable. For the px21 turtle beach gives you a 3.5mm to RCA Stereo Splitter Cable.
