I REALLY don't like these headphones. They have nice detail in the mids and highs, but the bass is just bad and resonates in the cups at 70 to 90. They hurt my ears, physically and acoustically. Live and learn. You get what you pay for. These cans are nasty. Very forward in the upper mids like bad old JBLs, boomy mid bass, no depth. I don't get it.
I'll gladly take those evil cups of torture off your hands if you hate it so much. How much time have you had them, give them a chance and some of that deep pounding bass burn-in. And maybe try some different pads..................... as others with comfort issues has been doing.
