Indeed, some mics need time to adjust. Going the opposite direction,  
one of my four AT3032s will pop intermittently for a few hours when I  
take it into sub-zero (f) cold. (This wouldn't be from condensation,  
would it?) The other three seem to handle the transition just fine.

In the process of setting them into new mountings last year, I lost  
track of which one it was. So I took advantage of this week's cold  
snap here in Minnesota to identify and mark it.
