I've had many comments about this little rig (pic on right). It's a simple earbud speaker/microphone boom - that came from a micro portable phone unit. I only use the microphone feature of this unit since the connector carries both speaker and mic. (A separate speaker connector is needed to plug into the FRS radio jack.)
The microphone boom currently permits me to speak over the PA system that is built up around Radio Shack's little $13 amp/speaker unit and an 'attenuation' box (left pic). This system permits one to project their voice, seemingly from the armor itself. You'll find additional information in my ARMOR TIPS section. A separate radio system is used to communicate with other Garrison members - that system is described within this TROOPER GEAR section.
