I have mentioned the mic issues back in the LOS 16.0 thread. Here's a collection of what the maintainers and also others said about it:

What I cannot seem to find right now is a statement of one of the maintainers about the mic driver(?), which would have to be reverse engineered, which is of course a really big thing, probably too much to ask for two maintainers who do this in their spare time. I hope I remember this correctly!
I don't expect the mic quality of this device to ever getting good or at least ok. The mic works, but it sucks. Everything else seems to be really good! It's such a pity. I'll keep it for emergencies which I had the other day.
