The amplification gains used were [dB]:
+40 +36 +31 +6 +37 +29 +57 +13 +55
The primary metric by which i'd judge them, is how quiet the silent periods are.
The results:
In my opinion, the best microphone is:
#8 robot-maker mic v2.
Also good are:
#2, #3 and #7/#9, although the #7/#9 are very quiet.
Interestingly, #4, while it was the loudest out of the box, has a non-stop loud buzzing noise.
