Lightly used with about 100 hours of listening on them and have been stored in their case unused ever since. Bought them for use with an open office (wanted something full closed but to not sacrifice on quality). Performed beautifully in that regard--comfortable listening even for 6 hours straight, no sound leakage, great performance--but have since moved on from that office and no longer need them.
I am the first owner, and have the original case and accessories (~3.94ft 4.4mm balanced cable, ~9.84ft 3.5mm cable, 1/4" adapter). Purchased new from dealer. Smoke-free household.
