His pair needed to be adjusted (bent) inward for better fit
He says ummm too much for me to get through with ez
But my thought is he needs to make them fit a little bit tighter and the stage and sound would have been better/ it amazes me when reviewers don’t fool around with cup fit more or the pressure test while listening to music
With my open back Kennertons I don't feel the need of more clamping force. I tried pressing the cups and the sound didn't improve as with the closed backs.
It really depends of the shape of your head tho.
