I use AKG 702's and the sonarworks plugin has been great for me in flattening the sound.
I guess it did sound unnatural at first but definitely confirmed what I already knew about my tendency to overcook the bass end to compensate for the lack of lows in the cans. With the plug in I can mix knowing that the results will be more even, provided I remember to disable it before exporting.

it also now has the same spectral balance as the room and speakers, which means I am hearing almost the same sound using either
