I have inherited speakers before, but not headphones. Those don't last after years of sweat/travel, the internals can break down, and the quality of headphone design has gone up with things like planar magnetic technology.
It's worth getting old headphones if they were the real top of the line like Stax electrostatics, since you can't afford new ones, but those were especially poorly built back in the day.
As for open headphones like AKG, people praise them for critical listening but I've found they're not good in realistic situations where there's any background noise at all. I can't get a separate soundproofed listening room in my apartment, so if the fridge decides to turn on, I can't hear the bass in an open headphone anymore.
