Two-wire Surveillance Kits allow teams to communicate discreetly without having to pick up a radio or activate a speaker mic. One wire connects the earphone to a clear acoustic tube and silicone eartip to listen to incoming communications. The microphone and PTT on the other wire fasten easily to a pocket, lapel or cuff.
