2-Wire Long Acoustic Airtube with Inline PTT/Microphone

The 2-Wire Long Acoustic Airtube Earpiece is one of our most popular designs, ideal for covert surveillance where discreet communication is crucial. The harness splits into two at the PTT/microphone, allowing the cable to be concealed under clothing with the earpiece running discreetly from the back of a collar or t-shirt. The speaker transducer delivers exceptional audio clarity, while the robust PTT and sensitive Electret condenser microphone ensure flawless communication even in complex environments. The threaded airtube can be easily removed, allowing the acoustic airtube alone to be issued personally to staff—resulting in significant cost savings.

Suitable across many industries, this earpiece is particularly favoured by security, police, casinos, nightclubs, hotel staff, restaurants, private detectives, and event coordinators.

Features:

Replaceable Long Airtube Section: The screw-in long airtube section (CRS-LATCD) can be purchased separately for a hygienic, cost-effective solution when sharing radios.
