Doug, the aliexpress headset does work fine with my radios (hence why I feel the diagram of the pin out is backwards). It's the electret microphone from Jaycar that I can't nut out. Looking inside the speaker mic I have (that also works fine) has those two extra components, which leads me to believe I need something like that in the wiring of the Jaycar one. The Aliexpress headset has no obvious extra components for the mic, but I haven't cut the mic up to confirm this.
The best case scenario is someone tells me I need electret "X" with no extra components and I can simply wire that up.
Otherwise, if I use electret "Y" I will need component "Z" to match the impedance or whatever needs doing to achieve compatibility. It looks to me like a surface mount diode and resistor in the speaker mic, but I'm not sure of what the components are
Cheers.
