I could not resist the temptation to try these against my trusty 650's. With my bottlehead Crack and the right tube combination, I can get my 650 in the same neighborhood as the 660s2. With regard to condition, you can't get a newer pair unless...well, you just buy them NIB. And these are indistinguishable from that. I auditioned them with my own pads and cable so that if I decided not to keep them, I could pass them on to the next person as open box. Includes all OG cables. Price is shipped and PP. Conus.
