Some info for the FP1. It looks like for the FP1 you want a TRRS (stereo-plus-mic) with OMTP and CTIA/AHJ. Or you will need an adapter.
You can have a look here to check if your headset is “Nokia” or “Apple” 
I think one works better with the FP1 the other better with the FP2 … But I’m not affected so I can’t tell you. Maybe reading about the issue a bit more will help.
The data is not arriving at the phone, I think. Not sure if software will help. There is a standard … and even more standards That seems to be the problem.
