ghost I believe you are mistaken, mic input can come from the usb port
Pin 1 +5V Red
Pin 2 -Data White
Pin 3 +Data Green
Pin 4 key (not connected)
Pin 5 GND Black
I believe pin 2&3 would be a hookup for the mic
and yes the talkman&chotto mics work for socom, killzone etc.
the question is the pinout for your mic connector, if it matches the psp
and determining how the psp determines a talkman/chotto is connected
