[ARSCLIST] headphones "break-in"?

[Tom Fine <tflists@xxxxxxxxxxxxxxxxxxx>]

Hi All:

Do professional headphones work optimally if one allows a "break-in" period or is this 
audiophoolery? I don't know enough about headphone driver design to know if a new pair benefits from 
playing relatively loud radio content or pink noise for a few hours to loosen up the mechanics. 
Based on the fact that I listen to headphones at ear-healthy low levels, this "break-in" would 
probably be as much "exercise" as the drivers would get, but if they are indeed "stiff" when new, it 
might be beneficial, too, for low-level listening (ie potential better dynamics response, better 
sensitivity for low-level bass, etc)??
