Two-Wire Comfort Surveillance Earpiece with Microphone and PTT – Black

The Motorola RLN5318A is a black two-wire surveillance earpiece designed for discreet communication with compatible Motorola portable two-way radios.

Two-Wire Configuration

The two-wire design separates the receive-audio earpiece from the combined microphone and PTT assembly:

• One wire routes audio to the acoustic-tube earpiece

• One wire positions the microphone and PTT near the user’s lapel or hand

This arrangement allows the accessory to be routed discreetly beneath clothing.

Translucent Acoustic Tube

The clear acoustic tube delivers incoming communications directly to one ear while maintaining a low-profile appearance. The earpiece can be removed for cleaning or replacement when required.

Combined Microphone and PTT

The microphone and push-to-talk button are combined into one accessible control. Users can transmit without removing the radio from a belt, holster, or carrying case.
