I don't.

Hifiman QA is exceptionally bad, and they tend to not stand by their warranty, and their US repair facility is just some dude's house.

The threads on /r/headphones over Hifiman shafting them are numerous.

Disclaimer: I too had a Hifiman pair, they sounded great, but their physical design just didn't hold up to daily use, no matter how much I babied them.

That's probably true, they do look hard to repair.

My best sounding headphones are a pair of old Stax with the worst construction I've ever seen on anything, so I mostly keep them locked up assuming they'll break if I breathe in them.

My Stax 207s, unfortunately, died on me.

I may just end up replacing them with something from ZMF.
