Does it count as reliable if I only have sample size of 1?
Beyerdynamic. Had DT770 pro for 8 years before they "broke" (cable connection failed, I think it's still fixable--making them last for many more years---by someone with skills I don't have, and they could have lasted more if I handled them a tad better.)
Recently I replaced them with DT770 pro X and they sound perfect to me.
