Do you think we don't all own several $100-200 headphones that we can demonstrably prove this wrong with?
I can't magically turn my Sony XB-500's into my AKG K712s, nor will they magically get EQd into my HD6XXs either.
EQ is something that can and should be done with basically every headphone/speaker system to give YOU the best sound for YOUR preferences.
If you imagine headphones are a painting and the sound they make is the color, EQ allows you to tweak that color to your preference, but it doesn't turn it into a fundamentally different painting.
