Receive-Only Flexible Earpiece with 3.5mm Plug for Remote Speaker Microphone

The Motorola Receive-Only Flexible Earpiece (WADN4190B) is a genuine Motorola Solutions audio accessory designed to connect to a compatible Motorola Remote Speaker Microphone (RSM) equipped with a 3.5 mm audio jack. The earpiece allows incoming radio communications to be heard discreetly through the user's ear while the Remote Speaker Microphone continues to provide Push-to-Talk and microphone functionality.

Designed for comfort and simplicity, the WADN4190B features a flexible over-the-ear design that helps keep the earpiece securely positioned during everyday professional use. Unlike an in-ear surveillance-style accessory, the flexible earpiece provides a straightforward listening solution that can be worn comfortably during extended shifts while keeping radio traffic from being broadcast through the RSM's external speaker.

The WADN4190B connects directly to the 3.5 mm accessory jack found on compatible Motorola Remote Speaker Microphones. Once connected, received radio audio is routed to the earpiece, providing greater privacy and making communications easier to hear in environments where using the speaker microphone's external speaker may be distracting or inappropriate.

Because this is a receive-only accessory, transmissions are still handled through the connected Remote Speaker Microphone. Users can listen through the WADN4190B and then communicate using the RSM's microphone and Push-to-Talk button, creating a simple combination of discreet incoming audio and familiar speaker-microphone operation.

The flexible earpiece is especially useful for security personnel, hospitality employees, retail staff, event personnel, transportation workers, and other professionals who need to monitor radio traffic without broadcasting conversations to everyone nearby. Its lightweight design also makes it a practical alternative for users who do not require a complete headset or surveillance kit.

Whether you're adding private listening capability to an existing Motorola Remote Speaker Microphone or replacing a worn earpiece, the Motorola WADN4190B provides a simple OEM solution for discreet receive-only communications in professional two-way radio environments.

How It Works

The WADN4190B is designed to be connected to the 3.5 mm audio jack on a compatible Motorola Remote Speaker Microphone.

Once connected:

• Incoming radio traffic is heard through the flexible earpiece

• The user presses the PTT button on the Remote Speaker Microphone to transmit

• The RSM's microphone captures the user's voice

• The earpiece remains dedicated to received audio

This makes the WADN4190B an excellent choice for users who already prefer operating their radio through a Remote Speaker Microphone but want incoming communications delivered more privately.
