I actually think this might be the case here, turn that off, only works with multiple driver headphones. My dt770 250ohm don't sound hollow at all, in any game. I ran em without an amp for years(laptop had one built in tho). I was instantly amazed by them too, no brain burn in required, had em almost 10 years now. I can barely use my gaming headphones, when I do I can't hear shit in fps and in other games they are fine, but still bad. They live in my neck for the mic now.
