It was really easy to do. I just repurposed the headband that came with the mic to make a round shape that would fit over an earpad, and used a bit of shrink wrap tubing to make it look clean.
And this is what I use currently:
It's a headband of a normal xbox mic glued on to the ear support mounting system of a bluetooth xbox mic. Not included in the picture is the earpiece from the normal mic. I glued that on to effectively have a normal xbox mic, but wireless (and comfortable!- the standard wireless mic was very uncomfortable for me). I can even rotate the mic relative to the headband still.
