Headset mic not working

I am still angry about the problems with headsets@FP2…

Currently I am puzzled very much, which in-ear-headset (with mic and 1 button) is working with the FP2 and which not.

The information about CTIA/OMTP and which smartphone model uses which standard, which headset have which standard…is confusing like hell! Only I know: FP2 needs CTIA and this, only partly useful list.

My problem:

  • Now I ordered a headset, which should work with HTC models (ONE M9 M8 Desire Eye A9)…and it do not work with the FP2 (same problems like here)
  • A friends Apple-headset does work with the FP2
  • Similar to the one I bought and which do not work with FP2 there exists several entries at ebay (germany) with the same, each stating different supporting smartphone brands…like here, here, here, here, here…but I don’t know:
    • if they are all the same and just claiming to support different smartphone brands
    • or if they really support different standards (–> so which is the correct one?),

I just want a very basic headset like this:

Wired in-ear stereo headset, with one button which work for calls, a mic, and from shop located in germany (not amazon).

  • ANY HINTS? Can anybody help my out with this?
  • Should ALL iPhone-Headset work with the FP2?
