Had these hanging my wall since 2015 (purchased new from the listening post). To be honest they're probably not even broken in yet (less than 5 hours use), I tended to use the SR80e's most (but now Bowers & Wilkins).
I don't have a price in mind as I haven't looked at the headphone market for ages but am open to all reasonable offers.
Excellent condition, from smoke free home but unfortunately not dust or cat hair free....
