I bought these in 2022, they are phenomenal, they sat in one room one pair of stands, they were not exposed to smoke in the room, there was a smoking lounge on the far end of the faculty opposite the room these were in but no direct exposure. It has one tiny white mark on the top of one speaker, other than that, they have no defects and that is the only cosmetic minor flaw. They are in amazing shape work perfectly. Upgraded to ATC SCM45a but love the kh310s. 3200 or best offer, call me, text me, make an offer, I want these gone soon so i can finish my art collection, if i'm being transparent. So if you want to negotiate i'm open to it.
