I have some Sony PS4 headphones where there's a metal rod going through plastic hinges. I would gladly pay an extra 100 bucks for a headset where any part of the device which is prone to wear would be made of metal, aluminum or otherwise. My larger than average head means that most headsets shatter after about a year of use.
I've got Audio-Technica ATH-A500, I don't think they make them anymore (now its A500X or something, so i can't vouch for that).
They look a little weird, but are sturdy as hell and sound plainly amazing (although after years of daily heavy use - connected to PC as exclusive sound source - they might seem to have a little lower sound quality - I'm not really sure)
I've literally stomped on them, run them over with a chair, had the cable go into the chair wheels (repeatedly) and then pull them off my head forcibly when I got up without noticing it. They are still fine.
I did break the audio jack when my headphone DAC fell of the desk and hit jackfirst into the ground (it sometimes doesn't connect properly and has to be wrangled about)
:(
