    I am replacing the TRRS plug on a friend's stereo headset that has a microphone attached to it. Is it safe for me to assume all headphone TRRS plugs use the same wiring convention? One step further, would that convention be the following:
    Tip = L phone
    1st ring = R phone
    2nd ring = Mic output
    Sleeve = common.

    I searched and found lots of PTT setups, and lots of TRS setups, but nothing useful to me for a TRRS like this.


    Thanks,

    Joe

    My logic is that when a TRRS plug is inserted into a TRS jack, the tip and first ring will still work like the tip and ring of a TRS plug so the phones still work but the mic won't.
