It's one of the advantages of saving a little more for a quality brand, especially those originally aimed at commercial/professional use.

Beyerdynamic has every part replaceable and the parts themselves are harder wearing (the pleather pads on my DT770 aren't peeling after 3-4 years, my near 20 yr old DT880 still look mint after a pad and headband change).

It ultimately costs less and is less wasteful than throwing out cheap pairs after a couple of years.
