Discreet 3.5mm Receive-Only Earpiece with Covered Earbud

Receive radio communications privately without broadcasting incoming audio through your speaker microphone with the Motorola AARLN4885B Receive-Only Earpiece.

This compact earpiece features a covered earbud and coiled cord for comfortable, discreet listening in security, public safety, industrial, and customer-facing environments.

The 3.5mm plug connects to the audio port on a compatible Motorola remote speaker microphone, allowing users to hear incoming transmissions while continuing to transmit through the microphone’s push-to-talk button.

Discreet Receive-Only Audio

The covered earbud directs incoming radio traffic to the user’s ear instead of playing it through the remote speaker microphone. This helps protect sensitive conversations and prevents radio traffic from disturbing customers, coworkers, or bystanders.

Connects to a Remote Speaker Microphone

The AARLN4885B plugs into the 3.5mm audio jack located on a compatible Motorola remote speaker microphone or public safety microphone.

It is not designed to connect directly to a portable radio unless the radio or attached accessory provides the required compatible 3.5mm audio port.

Receive-Only Operation

This earpiece does not include a microphone, push-to-talk button, or volume control. Users continue transmitting through the connected remote speaker microphone while receiving incoming audio through the covered earbud.

Comfortable Covered Earbud

The small covered earbud offers a simple alternative to acoustic-tube surveillance earpieces. Its lightweight, single-ear design allows users to monitor radio traffic while retaining awareness of conversations and activity around them.
