I bought DT880 about 2 weeks ago, and SRH940 a month ago. They are practically in new condition. I've used DT880 for 10 hours max, and SRH940 for 15 hours, used in pet and smoke free house.
I'll include all accessories that came with, and the leather earpads.
DT880 - SOLD
SRH940 for $240 shipped CONUS + paypal fee

EDIT - After posting this I am suddenly allowed to send more private messages, so I gave you my address.
