This is the beyerdynamic DT990PRO 250 OHM open-back headphones. I purchased these several years ago, and this is just the main unit. There is no original box, etc. I mentioned earlier that I didn't have the original 6.5mm adapter, but I found it. The items for sale are the main unit plus the original 6.5mm adapter. There are no issues with the sound. I don't think there are any major scratches, but there is some wear and tear. The headband and ear pads were recently replaced and are almost new. I replaced the original gray ear pads with black ear pads because I didn't like them very much. Thank you.
