Review on 🎧 Fancasee (2 Pack) Replacement TRRS 4 Pole Stereo 3.5mm Male Plug to Bare Wire Open End 1/8" Audio Cable for Headphone, Headset, Earphone, Microphone Repair by Jeremiah Butler

Luckily I tested them on a breadboard before soldering because the wire colors are not the modern CITA standard but the old OMTP standard. All this means that the green wire is connected to the third ring from the top and the black wire is connected to the bottom ring. For CITA compatibility you need to swap mic and ground; Green is ground and black is microphone. For OMTP, the colors are as expected. Check what standard your intended device uses and solder accordingly.
