Motorola MDRLN4885B 3.5mm Earbud | Genuine Accessory
If you need a reliable, discreet way to monitor radio communications, 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 incoming messages are heard only by you, making it ideal for noisy environments or situations requiring confidentiality.
How does the Motorola MDRLN4885B earbud connect?
This earbud features a standard 3.5mm plug designed specifically to attach to your existing remote speaker microphone. It operates as a receive-only device, meaning it does not include an inline Push-To-Talk (PTT) button, VOX capabilities, or programmable buttons. You simply plug it in and listen to incoming transmissions.
Is this earbud intrinsically safe?
Yes, when used with compatible equipment. The MDRLN4885B meets UL/TIA 4950 and FM intrinsic safety standards for specific Motorola GP Series, DP Series, and CP100 Series radios, ensuring safe operation in potentially hazardous environments.
Which Motorola radios are compatible?
This 3.5mm earbud is highly versatile. It is fully compatible with Motorola GP344, GP388, GP644, and GP688 handsets, as well as DP3400 and DP3401 models. If you are looking to expand your setup, it pairs perfectly with the Motorola GP Series Remote Speaker Mic or the Motorola GP340 Windporting Remote Speaker Mic. Alternatively, if you prefer a different style, you might consider the Motorola D-Shaped Earpiece with Inline PTT.
