YES -- this is why I consider turning off AGC a really bad idea, 
especially in a contesting environment where you have the RF gain 
cranked to copy a very weak station and a guy calls you with a signal 
well over S9.

Absolutely no difference between in-ear and circumaural to the extent 
that the transducers are linear.
