Dual-Pin Earbud With In-Line Microphone and PTT

The Motorola PMLN4294 Dual-Pin Earbud with In-Line Microphone and Push-to-Talk (PTT) provides a compact and discreet audio solution for compatible Motorola portable two-way radios.

Featuring a lightweight pellet-style earbud, the PMLN4294 delivers incoming radio communications directly to the user's ear. This provides greater privacy than listening through the radio's external speaker while allowing the radio to remain securely attached to a belt, carried in a case, or positioned elsewhere during use.

The accessory features a combined in-line microphone and Push-to-Talk (PTT) control, allowing users to transmit messages without repeatedly reaching for or removing the radio.

Its dual-pin radio connection provides a direct wired connection to compatible Motorola portable radios. The wired design requires no Bluetooth pairing, batteries, or separate charging, making it a simple and dependable audio accessory for everyday professional use.

The compact earbud is designed for comfortable extended wear and is particularly well suited for low-noise environments where users need discreet access to radio communications without the size and weight of a traditional headset or remote speaker microphone.

The PMLN4294 is ideal for retail, hospitality, security, education, property management, restaurants, event operations, maintenance, and other professional environments where lightweight and convenient radio communications are important.

Important

The PMLN4294 is a transmit-and-receive audio accessory. Incoming communications are heard through the earbud, while outgoing communications use the combined in-line microphone and Push-to-Talk control.

The PMLN4294 uses a dual-pin connection and should only be used with compatible Motorola portable radios equipped with the appropriate accessory interface.

Motorola documentation specifies that the PMLN4294 is not VOX-capable. Transmissions are initiated manually using the in-line Push-to-Talk button.

This accessory is primarily intended for low-noise environments. For high-noise workplaces, a noise-reducing headset or other appropriate Motorola audio accessory may provide better performance.
