1-Wire Receive-Only Surveillance Earpiece – Black

The Motorola 1-Wire Receive-Only Surveillance Earpiece, Black (PMLN6125A) is a professional audio accessory designed to provide discreet received communications with compatible Motorola professional portable radios. Featuring a streamlined single-wire design, black finish, and over-the-ear plastic ear-loop configuration, the PMLN6125A allows users to privately monitor radio traffic without broadcasting incoming communications through the radio's external speaker.

The PMLN6125A is a receive-only accessory. It delivers incoming radio communications to the user's ear but does not include its own microphone or Push-to-Talk (PTT) control. When a response is required, the user continues to transmit using the microphone and PTT controls on the connected portable radio.

The single-wire configuration keeps the accessory simple and minimizes cable clutter. With no separate microphone or PTT assembly to position, the PMLN6125A provides a lightweight listening solution for professionals who primarily need discreet received audio while keeping their radio readily available for outgoing transmissions.

Motorola identifies the PMLN6125A with a plastic ear-loop configuration and earbud-style earpiece. The over-the-ear arrangement helps keep the listening component positioned during everyday professional use while leaving the opposite ear uncovered for awareness of coworkers, customers, announcements, equipment, and other activity in the surrounding environment.

Unlike several other Motorola surveillance accessories, the PMLN6125A does not use a replaceable quick-disconnect translucent acoustic tube. Customers specifically looking for a clear acoustic-tube configuration should select the appropriate Motorola surveillance accessory for that application.

The black finish provides a professional appearance that blends naturally with many uniforms, workwear, and radio equipment. Combined with the compact single-wire construction, the PMLN6125A is well suited for security, hospitality, retail, transportation, public safety, industrial, and other professional communications environments.

Motorola identifies PMLN6125A with a TIA4950 (UL) intrinsic-safety rating and includes it in UL approval documentation for specific radio configurations. Hazardous-location approval depends on using the accessory as part of an approved Motorola radio, battery, and accessory combination. Motorola accessory documentation identifies this model as Non-FM, so customers requiring hazardous-location equipment should verify their complete approved configuration before use.

Whether you're equipping security personnel, hospitality employees, retail teams, transportation staff, or other professional radio users, the Motorola PMLN6125A provides a genuine Motorola receive-only solution combining discreet listening, streamlined single-wire operation, and a comfortable over-the-ear configuration.

Receive-Only Operation

The PMLN6125A is designed specifically for users who need discreet received radio audio without accessory-mounted transmitting controls.

The earpiece provides:

• Incoming Radio Audio

• Private Single-Ear Listening

• Simple Single-Wire Operation

• Low-Profile Professional Wear

Because the PMLN6125A does not contain a microphone or Push-to-Talk control, outgoing transmissions are made using the connected radio's microphone and PTT button.

Over-the-Ear / Ear-Loop Design

Motorola specifies the PMLN6125A with a plastic ear-loop configuration and earbud-style listening component.

This design provides:

• Secure over-the-ear positioning

• Lightweight single-ear listening

• Discreet received communications

• Reduced cable clutter

• Opposite ear remains available for environmental awareness

• Convenient wear during extended professional use

The PMLN6125A does not use the quick-disconnect translucent acoustic tube found on some other Motorola surveillance accessories.

Single-Wire Design

The PMLN6125A uses one wire for its receive-only audio connection.

Compared with more complex two-wire and three-wire surveillance kits, the single-wire design provides a particularly straightforward wearing configuration.

This makes it a practical choice for users who want:

• Minimal Cabling

• Private Received Audio

• Simple Everyday Operation

• Lightweight Wear

• No Separate Microphone/PTT Assembly

UL / Intrinsic Safety Information

Motorola specifies PMLN6125A with a TIA4950 (UL) intrinsic-safety rating and lists it within UL approval documentation for supported configurations.

Hazardous-location approval is dependent on the complete approved combination of:

• Motorola Radio

• Approved Motorola Battery

• PMLN6125A Earpiece

• Applicable Motorola UL Approval

Motorola accessory documentation identifies PMLN6125A as UL-TIA4950 / Non-FM. It should therefore not be marketed as universally FM-approved.

Customers requiring equipment for hazardous or classified locations should verify their exact radio, battery, and accessory combination against current Motorola approval documentation before use.

Compatibility

Motorola documents PMLN6125/PMLN6125A for multiple professional portable-radio platforms. Current Motorola information lists it with compatible professional products, while Motorola radio documentation also identifies it as an authorized accessory for select MOTOTRBO platforms.

Documented applications include select radios from families such as:

• Motorola APX Series

• MOTOTRBO XPR Series

• MOTOTRBO DP Series

• XiR Professional Portable Radios

• Additional Compatible Motorola Professional Radios

Compatibility varies by exact radio model, region, and configuration. Customers should verify their specific Motorola radio before ordering.

• PMLN6125A – 1-Wire Receive-Only Earpiece, Black

• PMLN6126A – 1-Wire Receive-Only Earpiece, Beige

Motorola lists both as receive-only surveillance accessories intended for users who require discreet incoming radio audio without accessory-mounted transmitting controls.
