I have a 4 pin mini-jack headphones and 4 pin mini jack microphone (BOYA). I want to plug them into the Mac Air but I have a 2x3 pin to 4 pin splitter and it seems that it doesn't work - the computer doesn't see the microphone. What should be the splitter to plug it all at a time? I thought 2x4 pin(f) -> 4 pin(m) but I haven't been able to find one. Will a 4 pin -> 3 pin adapter work if I plug the microphone to it and then plug it into my splitter together with headphones? What adapters or splitters should I purchase to make it work?
The microphone works well when I plug it into the headphones multi hole directly but doesn't when I plug it into the splitter with headphones. Two 4 pin headsets work well through a splitter that I have (output is 4 pin, but I don't know what is there at the inputs). Microfone and headset don't work with this splitter.
My adapter OMTP - CTIA is here (link) and I tried to plug the microphone in different ways, but unfortunately the MAC doesn't see it through the splitter.
