I have an older Telex headset that is mono  and only has two wires for the speakers and two wires for the microphone. I have  the speakers wired up and they work fine. 

     The microphone has two  wires but the plug has three solder connections on it, Tip, Ring, Sleeve....  Which is the proper location for these two wires for it to work..

The tip is intended to carry the Push-To-Talk line.

The ring is mic audio 'hi' or 'positive' or '+'.

The sleeve is 'lo' or 'return' or 'ground', depending on who writes the 

docs.



If you have an inline portable PTT switch, when you push the button, the 

tip is connected to the sleeve (pulling the PTT sense line in the radio 

to near zero volts), telling the radio to go into transmit mode.

 ===========================

  

 The proper plug is called a TRS (tip, ring, sleeve) and the mic connections  on a normally wired aircraft are MIC=Ring and MIC_RTN=Sleeve.  If you use  an external (inline) Mic key switch then MIC_KEY=TIP.
