Found out that this tool does it with the available resolution:

DATAMATRIX DTV93715PEKL8141N+DC

Unfortunately it doesn’t align with any of their known part numbers.

Can’t help you on the chips, but the microphones are from Goertek, as they have the “GW” marking.

See page 6 of this confidential datasheet for another mic in the same range. If you can get a high enough picture of the datamatrix code on the microphone, it should contain the part number, but the photos are too low resolution for me to read it myself.
