Description
3-Wire IMPRES Surveillance Earpiece Kit with Translucent Tube
Genuine Motorola Solutions Original 3-wire covert surveillance earpiece with separate microphone, discrete PTT button, and wideband loud audio acoustic tube.
The Motorola PMLN8343A (also cataloged as PMLN8343) is an authentic original equipment manufacturer (OEM) 3-wire surveillance audio kit engineered specifically for discrete communication in challenging high-noise environments. Designed for executive protection details, covert surveillance teams, public safety officers, and industrial security personnel, this professional headset separates control, transmit, and receive lines into three distinct pathways for covert routing beneath duty uniforms or tactical gear. Sourced directly from our verified inventory of Two-Way Radio Earpieces, the PMLN8343A delivers covert operations capability while unlocking wideband acoustic intelligibility.
Engineered with genuine Motorola IMPRES™ smart audio technology, the Motorola PMLN8343A communicates directly with your host radio to optimize incoming voice levels, suppress background noise, and support enhanced loud audio features. Built to meet stringent occupational safety requirements under OSHA Standards and certified intrinsically safe under UL Standards for hazardous environments when paired with approved radios, the kit features a specialized 3-wire configuration: one dedicated wire for the clear acoustic ear tube, a second wire for the lapel microphone, and a third wire running down the sleeve to a discrete Push-to-Talk (PTT) switch with an integrated programmable button. The surgical-grade coiled acoustic tube features a quick-disconnect twist-lock fitting, allowing users to replace worn tubes or share hardware hygienically between shifts.

Frequently Asked Questions
How does a 3-wire surveillance kit differ from a 1-wire or 2-wire kit?
A 1-wire kit combines the microphone, PTT, and earpiece on a single line; a 2-wire kit splits the earpiece from a shared mic/PTT pod. This 3-wire kit separates every function into its own dedicated wire: one wire runs to your ear, one clips to your lapel or collar for voice transmission, and the third runs down your jacket sleeve to your palm for discrete, concealed push-to-talk operation.
What does the programmable button on the PTT module do?
The secondary button on the PTT pod mirrors programmable side buttons on your host radio. It can be mapped in radio programming software (CPS) for quick access to critical functions such as emergency duress alarms, channel monitor, or volume toggle.
What makes IMPRES™ audio beneficial on this surveillance kit?
Motorola IMPRES technology enables bidirectional communication between the accessory and the transceiver. The radio detects the earpiece, optimizes automatic gain control (AGC) for whisper-level covert speech, and activates wideband loud audio profiles to ensure clear intelligibility in noisy venues.
Is the clear acoustic tube replaceable?
Yes. The translucent tube utilizes a quarter-turn quick-disconnect elbow that locks onto the speaker transducer. It can be replaced at any time using the authentic Motorola PMLN8092A replacement tube kit.
Does this earpiece fit legacy Motorola MOTOTRBO radios like the XPR 7550e?
No. The PMLN8343A utilizes Motorola’s newer GCAI-Mini multi-pin interface engineered for the MOTOTRBO R7, MOTOTRBO Ion, and APX N-Series. It does not fit the larger legacy GCAI multi-pin connector on XPR 6000 or XPR 7000 Series radios.
