Yeah. I have a pair of AKG M240 mkii headphones I bought not that long ago and have started using regularly. I'll get something I think sounds good in the monitors, pop the headphones on and then quickly realize that there's too much 250 Hz. Fix it, take the headphones off, and you can't preceive the difference in the monitors really but it's a better balanced mix. I try to never say I'm done without taking the mix to a different space and taking notes. It just reveals sooooo much.
