For the elite private security, we offer the Executive 3 Wire Surveillance Mic.
The Executive Three-Wire Microphone is a true stealthy surveillance kit. One wire is the earpiece (just like Sherlock/Investigator), one wire is the microphone, it is a small barrel type that pins inside the shirt, the third wire is a PTT that can be fed down the shirt sleeve to be held in the palm. Kevlar® reinforced cable guarantees reliability.
A great undercover surveillance headset.
