When you say 'fail to find .... that works' are you talking about getting it to work in a particular a/c type? or with particular other type of headset?
What symptons do you have?
I'm no expert on this but I believe that most compatability problems relate to the impedance of the microphone, rather than the headset.
So if you take a hifi headset, and then add a boom mike, you may not solve the problem.
