Nearly all mics are adjustable for gain, if one has the manual and knows what they are doing.
All too often, however...the gain is turned up too high, which often results in distortion for the receiving station.
Easy does it, with adjustments.
Example,
As I use a David Clark H10-30 headset in my private airplane, a
very small clockwise adjustment was all that was needed.
The tower responded...'loud and very clear, what kind of radios are you using?
My response...'King Gold Crown, forty years old and still working to perfection'.
These comm sets (KTR9000 series) were installed in UAL B737's in 1969, and yes, they still work
good. Collins 618 series...likewise.
Heavy?
Yes, however, very reliable.
NB.
I have friends who have Garmin 430/530 sets, which include comm units. and these have proven rather unreliable, in extended service.
Great...you can navigate, but not communicate.
Wonderful...
