The DT 1770s are very warm and can even exhibit over excursion of the drivers when playing loud sub 40Hz frequencies. All fixed with this equalizer.
I've also started using Windows Sonic. I use to hate it, but now it sounds great with this card and the settings I use. Dolby Atmos for Headphones and DTS Unbound mess too much with the dynamic range and have compatibility problems. Those two options are good to use with lesser headphones. Windows Sonic is basically flat with only virtualization added. I apply Nahimic post process 2-channel surround on top of it.
I don't use EQ at all.
I hope you downloaded 2.1.14 driver version and flashed the card with the latest firmware.
