Disclaimer: I haven't tried myself, so I don't know if this would work without additional equipment.
The two pins are 3.5mm and 2.5mm. The 3.5mm is for the speakers and the 2.5mm is for the mic. With a 2.5mm female to 3.5mm male adapter/cable, you might be able to use any speaker microphone with the same pin setup as your mic. I'm not sure if it would always be on or if pressing the talk button would work. It's something I'm considering trying myself just for fun.
That's similar to what I use. I use a Retevis PTT (Which is shit) and Howard Leight Impact Sports. Works pretty well for the price. A nice Code Red PTT would be great.
