It might be worth trying some different pads on them. I have Dekoni Choice Leather on mine, it changed the sound for the better and was more comfortable due to the memory foam. The way any headphone seals to your head will drastically change the sound and maybe the stock pads just aren't for you. My DT770's sound great, they did sound a bit "shouty" at first, but the pad change helped that some then just getting used to them was a big difference. Now if I go back to my old HyperX Cloud Alphas, they just sound horrible and muddy.
