Enhanced 1-Wire Clear-Tube Earpiece with Microphone and PTT – Angled 2.5 mm

The Motorola PMLN8191A is an enhanced one-wire surveillance earpiece designed for discreet communication with compatible Motorola Curve, Evolve, and TLK 110 devices.

A clear acoustic tube delivers incoming audio privately to one ear, while the streamlined in-line microphone and push-to-talk button allow users to transmit without handling the radio or communication device.

The PMLN8191A features an angled 2.5 mm single-pin connector that provides a low-profile connection at the device. Its enhanced audio design makes it a practical choice for demanding professional environments and extended shifts.

Enhanced Clear-Tube Audio

The clear acoustic tube routes incoming communications directly to one ear for discreet listening. Its low-profile appearance is useful for security, hospitality, retail, and other customer-facing environments.

In-Line Microphone and PTT

The combined in-line microphone and push-to-talk control allows users to respond quickly without removing the communication device from a belt, pocket, holster, or carrying case.

Angled 2.5 mm Connection

The angled single-pin connector helps keep the cable positioned close to the device, reducing unnecessary protrusion compared with a straight connector. This plug style is different from the straight 2.5 mm connection used by some other Motorola earpieces.

One-Wire Design

Audio, microphone, and push-to-talk functions are routed through a single cable. This simplifies installation and helps keep the accessory discreetly positioned against the user’s clothing.
