I talked with fire fox and they said it should work just fine. It is a two pole 2mm plug in. Meaning the two bands around the pin that plugs into the unit are the poles. the ROM has a 3.5mm plug in but you can purchase a converter from 3.5 to 2mm at Radio Shack. I bought one for just a couple dollars because I was trying to use my boom from my cell phone but it end up being to far from my mouth. They have the sportsman model at firefox for 34.99. You can add a FSR radio later on if your garrisonsquad wants to be able to keep in contact. It has a switch
to crossover. I have the Radio Shack headset with the bendable boom mic and its a pain in the @##! Especially if you wear a TE helmet. The boom is sandwiched in between my two fans that are mounted on the frown which leaves a hum through the voice amp. Sounds like I'm carrying a small powerplant on my back. Here is how it works
