1-Wire Earpiece with Clear Acoustic Tube – Black, 3.5mm Threaded

The Motorola 1-Wire Earpiece with Clear Acoustic Tube (RLN5313B) is a professional receive-only audio accessory designed to provide discreet and private radio communications when connected to compatible Motorola Remote Speaker Microphones and audio accessories with a threaded 3.5 mm connection. Featuring a black cable, clear acoustic tube, and low-profile earpiece design, the RLN5313B is an excellent choice for professionals who need to monitor radio traffic without broadcasting incoming communications to people nearby.

The clear acoustic tube delivers incoming radio audio directly to the user's ear while maintaining a discreet appearance. This surveillance-style configuration is especially useful for security personnel, hospitality employees, event staff, retail loss-prevention teams, and other professionals who regularly work around customers, guests, or the general public.

The RLN5313B uses a threaded 3.5 mm accessory connection designed for compatible Motorola audio equipment. The threaded connector helps provide a more secure attachment than a conventional non-locking audio plug, reducing the likelihood of the earpiece becoming accidentally disconnected during active professional use.

As a receive-only earpiece, the RLN5313B does not include its own microphone or Push-to-Talk control. Users continue to transmit through the microphone and PTT button on their compatible Remote Speaker Microphone or other connected audio accessory, while incoming radio traffic is routed privately through the RLN5313B.

The one-wire configuration keeps the accessory simple and lightweight while minimizing unnecessary cabling. The black cable can be routed along or underneath clothing, while the translucent acoustic tube remains unobtrusive near the user's ear. This makes the earpiece particularly practical for uniforms and other professional workwear.

Whether you're equipping security personnel with discreet communications, adding private listening capability to compatible Motorola Remote Speaker Microphones, or replacing an existing acoustic-tube earpiece, the Motorola RLN5313B provides a dependable OEM solution for professional receive-only radio audio.
