I bought these along with a couple of other highly rated headphones to audition while I was waiting for my Sonoma Acoustics Model One to arrive. They were in rotation for a couple of months, so very lightly used. If I didn't have the Model One these would be keepers. I never realized how noisy even a "quiet" room was until I tried these. The noise cancelling is there to improve the signal to noise ratio in normal listening. There is a reason they were selected for the January 2018 Absolute Sound Ultimate Guide To Headphones. Headphones come in original packaging with ALL original accessories: 4 cables, leather case, hard case and battery to recharge them. And, they covered by a lifetime warranty from AKG. I cover PayPal fees and shipping.
