Motorola BDN6730A 3-Wire Surveillance Kit
Model Number: BDN6730A
This earpiece allows the radio user to privately receive messages and is ideal when environments require discreet communication. This black, 3-wire earpiece has a separate microphone and Push-to-Talk feature, and it’s intrinsically safe. It requires a 3.5mm threaded audio adapter, unless being used with a speaker microphone.
