Purchased these as “open box” and I don’t think they were ever used. Sound fantastic and compare well to Sennheiser and beyerdynamic headphones I own, but sound a little different—not is a good or bad way, but different. If you own $500 headphones, these will not disappoint, at under $250.
The audio of these beauties is awesome!!! Natural, clear... yes, something dark, but after a while it's beautiful! The perfect complement for my Grados's PS500e
