I have only used these 5 times, I think. Excellent headphones, as many of you know. I have both sets of earcups and the 1/4" jack adapter. They should go to a good home of an adi-file. My go-to on-the-ear headphones are the aluminum version of the HD-25. $100, plus shipping, and you can have these. They are no longer making them and I think that I paid around $250, new.
