QDC Full Bone Conduction Tactical
Communication System
 QDC Full Bone Conduction Tactical Communication System is developed
based on bone conduction technology. Its unique feature lies in the fact that
it coverts the audio signal with electromechanical transducer and directly
transfer vibration signal to ear with the facial bones. This enable the user to
receive clear voice and environmental sound.
QDC Full Bone Conduction Tactical Communication System consists of nylon
head strip, adjustable spring-loaded steel clip, accurate mini microphone,
control switch. QDC Full Bone Conduction Tactical headset has both receiving
and speaking functions, compatible with all radios. It is ideal for use in
anti-terrorism, SWAT, police, fire fighting, traffic police, etc.
