Speaker component has 3 wires: left signal, proper sign and common go back (floor). Microphone component has 2 wires: bias signal and go back (floor). Return (floor) is every now and then mixed into one from each components, so a few cables have 4 wires, some 5 wires, a few cables have easy cables for speaker with a floor putting free outdoor but a one at a time shielded microphone twine. Signal wires are usually insulated; floor wires on occasion are however typically aren't. If we were to go without a multimeter, you need to determine whether or not (a) the skinny wire on the left is insulated, and (b) whether or not the thick one on the left has a copper shield, then an insulator (may be clean lacquer) and any other twine inner it. Inside the (a) case, that wire could be for the microphone. Within the (b) case, the internal of that cord may be for the microphone. You could locate whether a wire is insulated with the aid of lacquer with the aid of the use of a cigarette lighter, the lacquer will burn. By using elimination, you would possibly discover which wires have to go to the speakers.
You'll commonly need to use a continuity tester (maximum convenient is to use an off-the-shelf multimeter in diode beep mode; however you could additionally use a battery and a buzzer) to find out where the leads move in your headset and at the jacks. There is no wellknown by way of which i may want to say "join this colour to this colour and you'll be nice".
