Motorola MDRLN4885B 3.5mm Earbud | Genuine Accessory
Enhance your daily communication with the genuine Motorola MDRLN4885B earbud. Featuring a standard 3.5mm plug, this receive-only earpiece connects directly to your remote speaker microphone, providing discreet, clear audio for your compatible DP series two-way radios.
If you need a reliable, discreet way to monitor incoming radio traffic, the genuine Motorola MDRLN4885B earbud is an excellent choice. Designed to plug directly into your remote speaker microphone (RSM), this receive-only earpiece ensures that your conversations stay private, even in noisy or public environments. Whether you are managing a busy retail floor or coordinating security, this simple addition to your radio setup makes a massive difference in how you communicate.
How does the Motorola MDRLN4885B earbud work?
This earbud is designed specifically for receive-only operation. It features a standard 3.5mm plug that connects directly to a compatible remote speaker microphone rather than the radio itself. Because it does not have an inline push-to-talk (PTT) button, VOX capability, or programmable buttons, it serves a single, highly effective purpose: delivering clear, private audio straight to your ear.
Which radios are compatible with this earpiece?
The MDRLN4885B is highly versatile and works seamlessly with remote speaker microphones used alongside the Motorola DP1000, DP2000, DP3000, and DP4000 series radios. If you are currently using a Motorola DP1400, this earbud is a perfect match for your compatible RSM. Please note: Due to hygiene reasons, earpieces are non-refundable, so we highly recommend verifying your RSM connection type before purchasing.

Looking to upgrade your DP series setup?
