2-Wire Short Acoustic Airtube with Inline PTT/Microphone

The 2-Wire Short Acoustic Airtube earpiece is designed to be discreet, lightweight, and comfortable for all-day wear. The harness splits into two at the PTT/microphone, allowing the cable to be easily concealed under clothing with the earpiece discreetly running up from the back of a collar or t-shirt. Its covert speaker transducer delivers exceptional audio clarity, while the heavy-duty PTT and sensitive Electret condenser microphone make it ideal for noisy environments. The threaded airtube can be quickly removed, enabling the acoustic airtube alone to be issued personally to staff—resulting in significant cost savings.

Suitable for a variety of industries, it is especially popular with security, police, nightclubs, hotel staff, and event coordinators.

Features:
