I bought mine used for an absolutely stupid price that was too good to pass up. Glad I didn't at this point. Number of hours? Unknown. Take previous hours + my own hours (there's at least 4 hours per day, if not more, playing through my D5k's per day). But I also have them playing even when I'm not actively wearing them. I have a dual setup so two headphones play at once, and I generally swap between two throughout my sessions.
Very best,







How many hours do you have on yours now?
