3.5mm TRRS Left Audio (Tip), Right Audio (Ring), Mic/Video (Ring), Ground (Sleeve)

I just tore apart a male end of a 4-conductor 3.5mm cable for a little project I'm doing. I'm having a hard time differentiating between the colored wires. 

 

I need the left audio, right audio, and ground wires. Is anyone familiar with this type of male end and the soldering?

It appears the green is ground but that's all I can gather.

 

I appreciate any insight. Thanks!

T = left

R = right

R = ground

S = mic

 

The above is for an iphone style headset, some TRRS headsets also have the mic and ground switched about but is less common.

 

If you need to work out which one is ground on your headset, you could use a multimeter on resistance setting. Between the ground and left(or ground and right) the resistance should be somewhere in the 12 - 120 ohms sort of range depending on the impedance of the headphones

 

As for which colored wires correspond to which conductor, work your way from the inside out (or use a multimeter). The inner most conductor has to be the tip, then then innermost ring is the closest to the tip and so on...

 

So from your picture:

 

T = red

R = white

R = yellow

S = green

Great! I was able to use a multimeter and you are correct. TRRS was red, white, yellow, green. I'll be using it on my Galaxy S3 and I believe when I google the pinout for it, it is actually Left audio, right audio, mic, ground. I read somewhere that only proprietary apple was left, right, ground, mic. 

 

Thanks for your help!
