1-Wire Enhanced Clear Tube Earpiece – 2.5mm Single-Pin Straight

The Motorola 1-Wire Enhanced Clear Tube Earpiece (PMLN8190A) is a professional two-way radio audio accessory designed to provide discreet, comfortable communications through a streamlined single-wire configuration. Featuring an enhanced clear acoustic tube, 2.5 mm single-pin straight connector, and low-profile design, the PMLN8190A is ideal for professionals who need private radio communications while maintaining a clean and unobtrusive appearance.

The enhanced clear acoustic tube routes incoming radio communications directly to the user's ear, helping prevent radio traffic from being openly broadcast through the radio's speaker. Its translucent construction provides the discreet surveillance-style appearance commonly preferred by security personnel, hospitality employees, retail loss-prevention teams, event staff, and other professionals who work directly around customers or the public.

The PMLN8190A uses a 2.5 mm single-pin straight connector designed for compatible Motorola radio equipment. The straight connector provides a compact connection to the supported device while the single-wire design keeps the overall accessory simple and easy to route around professional clothing.

The one-wire configuration minimizes cable clutter compared with multi-wire surveillance accessories. This makes the PMLN8190A particularly convenient for users who want a lightweight audio solution that can be worn throughout an entire shift without the additional cables associated with more complex surveillance kits.

The clear acoustic-tube design also allows wearable ear-contact components to be maintained or replaced as needed, helping organizations keep frequently used audio equipment comfortable and ready for daily deployment. For larger fleets, maintaining compatible replacement components can help extend the useful service life of existing audio accessories.

Because Motorola uses multiple accessory connector types across its professional communications portfolio, customers should verify that their specific radio or device supports the PMLN8190A's 2.5 mm single-pin connection before ordering. This is especially important when replacing an existing earpiece, as similar-looking Motorola audio accessories may use different connector configurations.

Whether you're equipping security personnel, hospitality teams, retail employees, or other professionals requiring discreet received communications, the Motorola PMLN8190A provides a compact OEM solution combining an enhanced clear acoustic tube, streamlined one-wire design, and 2.5 mm single-pin straight connection.
