Description
2-Wire Surveillance Earpiece
OEM black covert surveillance earpiece with inline microphone and PTT.
The Motorola RLN5318A (also designated as RLN5318) is a genuine OEM two-wire surveillance and covert earpiece kit engineered for discreet, hands-free communications across professional commercial environments. Combining an extended-wear comfort earpiece with a soft rubber eartip, clear translucent acoustic tube, and an inline microphone and Push-To-Talk (PTT) assembly, the Motorola RLN5318A delivers high-clarity voice reception and transmission while maintaining a discreet, low-profile appearance.
Designed for security teams, hospitality staff, retail managers, and event coordinators, the Motorola RLN5318A allows operators to privately receive messages in environments that require confidential communications or noise reduction. The kit features a two-wire layout: one wire routes directly to the clear translucent tube and rubber eartip, while the second wire leads to the combined inline microphone and PTT switch. This separate two-wire architecture allows users to conceal cables beneath jackets or uniform shirts for an organized, professional setup. The comfortable ear tip channels incoming audio directly into the ear canal for clear reception, while the sensitive inline microphone and PTT button enable instant voice transmissions at collar height.
