There seems to be several different wire coloring systems (see below)
Pin |
Color | Description (may be empty) |
1 | Blue | Microphone signal |
2 | White | Right audio channel |
3 | Red | Left audio channel |
4 | Green | Left ground |
5 | Yellow | Right ground |
6 | Black |
Microphone ground |
The pins on this headset use the same levels as a regular microphone and pair of stereo headphones; a simple adapter can be made using two 3.5mm barrel connectors.
On the headsets I have here the pinout is:
White & Green = common (ground)
Black = right audio
Red = left audio
Blue = mic. ground
Yellow = +ve voltage AND mic. audio
