The two wire short acoustic airtube earpiece has been designed to be discrete, lightweight and comfortable. The 2wire harness splits into two at the PT/Mic enabling the user to conceal the cable underneath their clothing with the earpiece running up from the back of the collar/tshirt, etc. The covert design of the speaker transducer gives exceptional audio quality. The heavy duty PTT design coupled with the sensitive Electret condenser microphone makes this a perfect product for noisy environments. The threaded airtube can be removed easily to enable JUST THE ACOUSTIC AIRTUBE to be made personal issue for staff - GREAT SAVING.
Suitable for all industry types but a particular favourite with security, police, night clubs, hotel personnel, event co-ordinators ......
