There are several different things you can do here. Check out
http://www.prymebattery.com/ for a list of accessories. I have used throat mics, ear buds w/ PTT inline mics, ear buds w/ attached boom mics, and finally the hand held CB style mic/speaker. The throat mics fairly work good but my neck is to small for it to stay in the sweet spot on your neck. Lots of players have success using the ear bud with the inline PTT mic. I have found the ear buds with the boom mic attached tend to get uncomfortable after a while just from the little ear hook thingys on them.
So far I prefer my current set up which uses the CB style hand held remote speaker/mic. It has a jack on it to hook up an single ear bud speaker. When you attach that to it it bypasses the handheld speaker to keep things private between you and the radio traffic. I like this set up the most so far.
-The handheld mic PTT button is easy to actuate under combat stress.
-I can remove the ear bud piece so I can broadcast the play by play to others when needed through the handheld speaker.
-I am less likely (zero chance) to drop and loose my radio when its secured in a pouch and I use the handheld speaker/mic.
-Looks cool.
