Description
Quick-Disconnect Replacement Acoustic Tube with Rubber Earbud
Genuine Motorola Solutions Original clear coiled acoustic tube and rubber eartip replacement kit for commercial and public safety surveillance earpieces.
The Motorola PMLN8092A (also cataloged as PMLN8092) is an authentic original equipment manufacturer (OEM) replacement audio assembly designed to maintain and restore the acoustic performance of Motorola surveillance earpieces. Engineered for security officers, executive protection details, hospitality staff, and frontline public safety personnel, this kit features a high-grade transparent coiled acoustic tube and a soft mushroom-style rubber earbud. Sourced directly from our comprehensive selection of Two-Way Radio Earpieces, the PMLN8092A provides an economical, hygienic solution that restores crisp, clear receive audio without the expense of replacing entire surveillance wiring harnesses, microphones, or radio connectors.
Over extended operational deployment, acoustic tubes naturally accumulate moisture condensation, atmospheric grime, and earwax, resulting in muffled, low-volume, or distorted incoming voice communications. Designed with an ergonomic quick-disconnect twist-lock fitting, the Motorola PMLN8092A snaps on and off the transducer housing in seconds without requiring tools or radio reconfiguration. Engineered in compliance with OSHA Standards for occupational hearing conservation and clear speech intelligibility in high-noise environments, the discreet surgical-grade tubing delivers distortion-free sound while maintaining a covert, professional profile. Sourced alongside our verified lineup of Motorola Two-Way Radios & Accessories, keeping spare acoustic tubes on hand ensures immediate duty readiness when reassigning headsets across rotating shifts.

Frequently Asked Questions
Which surveillance earpieces use the PMLN8092A replacement tube?
The PMLN8092A is the official factory replacement tube kit for Motorola commercial and public safety surveillance earpieces, including the PMLN8120 (3.5mm receive-only earpiece), PMLN8341 (1-wire IMPRES kit), PMLN8342 (2-wire IMPRES kit), and PMLN8343 (3-wire IMPRES kit).
How do I know when it is time to replace my acoustic tube?
You should replace the acoustic tube if receive audio sounds unusually faint or muffled, if visible moisture, perspiration, or earwax has accumulated inside the coiled tube, or if the plastic tubing has become hardened, discolored, or kinked from long-term wear.
How does the quick-disconnect mechanism work?
The tube features a notched elbow connector that slots directly into the round acoustic transducer barrel of compatible Motorola surveillance earpieces. A simple quarter-turn twist locks the tube firmly into place or releases it for replacement.
What does the "Mackenzie" and "Rajang" reference mean in compatibility?
In Motorola Solutions' factory accessory database, Mackenzie is the internal engineering project designation for the MOTOTRBO Ion smart radio platform, and Rajang refers to dedicated industrial board hardware used in select European and international digital series. Surveillance earpieces designed for those platforms utilize this exact PMLN8092A tube kit.
Does this replacement kit include the speaker transducer or microphone cable?
No. The PMLN8092A is an audio acoustic wear kit that includes only the clear coiled plastic tube and the soft rubber earbud. It is designed to snap onto your existing surveillance kit's audio transducer housing.
