Your headset mic, does it share the headphoneplug or is it separate (doyou have one plug, or two)?

If it’s one then I do not think it will work. It will cut out the onboard mic as it will open that part of the curcuit to disable it. It will also, most likely, have 4 or 5contacts on the plug (tip, usually ground, 2 or 3bands, one for mic and others for left and right headphone,and the part that enters the “handle”).

If it has 2 separate plugs, are you sure you are not plugging in the headphone instead of the mic?
