usbroway 3.5mm Listen Only Acoustic Tube Earpiece

Product Type and Intended User

This is a 3.5 mm listen-only acoustic tube earpiece for two-way radios. It connects to any speaker microphone that provides a 3.5 mm receive-only audio jack. The design targets police, security and law-enforcement personnel who need discreet, clear audio reception in loud environments. The package includes three earmolds for different ear-fit preferences.

Who It Suits and Who Should Look Elsewhere

Professionals who wear a speaker mic on the shoulder or chest and want a lightweight, coiled acoustic tube running to one ear will find this comfortable for extended shifts. Buyers who need a transmit microphone, push-to-talk button or inline volume control cannot use this receive-only model. It is also unsuitable for anyone requiring an intrinsically safe rating or waterproof construction for hazardous or wet conditions.

Build Integration and Constraints

The earpiece plugs directly into the 3.5 mm listen-only jack on compatible Motorola, Kenwood, Baofeng, Icom, Harris and Commountain speaker mics. No additional adapter or power source is required. The high-purity copper cable with anti-interference circuitry and TPU jacket resists tangling and keeps the audio path clean. Because it lacks intrinsic safety certification and water resistance, it must be kept out of explosive atmospheres and rain.
