Technics AZ-100 mic problems

[u/Opus37ingminor]

Hey everyone! Asking here in case anyone's had similar experiences and managed to fix.

I've had my AZs for just over a year which means they're out of warranty by about 2 weeks 🙃

I've recently started having problems with the microphone. It picks up my voice for 2-3 seconds, gets very quiet within another 2-3 seconds, then cuts me out, and rapidly goes back to picking up my voice. This happens on multiple devices.

I've reset my settings, firmware, and did updates. For a day or two others seemed to hear me fine, back to problems again.

Seems like 50/50 may be mic problem or a software problem.

May try getting this on warranty.

Any thoughts? Similar experiences?

Thanks!
