🎤 Motorola Original PMMN4021A Microphone: Ultimate Compatibility and Performance Review

Great sound and great sound. This Motorola item works on all listed Motorola models that I have access to. It also has a 3.5mm mono headphone jack.

I've had this for a few months and it's holding up well so far. My previous lavalier microphone stopped working after a few years. It should last at least as long. The transmission and sound quality is excellent.

Seems to work great for the first month but now the microphone speaker transmits sound but when the button is pressed to talk it doesn't work most of the time. Transmissions are not received from other radio units. Very dangerous in my line of business. Conveniently the seller won't take it back as it's outside the return window.
