You know it's also hard to sit and demo a headphone for a moments use you're not familiar with, coming from a gaming headset especially, but all headphones. It may strike you as oddly off or hollow, particularly when coming from a HP with bass boost, or a more forward mid, or virtual surround. Takes time for your hearing to adjust to the new sound character. Also I don't think the dt770 80 ohm is all that impressive. Not to knock it at all. It's good as far as closed backs are concerned for quiet/less bleed use cases, but an open back gains you more natural detail and soundstage. Also, try the higher ohm version with a dac and amp. Or the dt 990.
