ATH M50X have a better frequency response without treble rape and don't have the retarded design choices Beyer cans have. You're fine.

Audeze cans have this unique suction cup like sensation when you take them off. Kind of like when you're on an airplane since they seal very well and as a result have flat bass down to even 10 hz. If you didn't feel anything like that then the seal was probably imperfect. Hifiman cans all feel "thin" but Audeze are anything but imo.
