I rarely have previous experience with the products being sold on woot and therefore rarely comment but this time…I do already own the product.
The AKG K495NC are indeed very good quality. I have used these numerous times on both short domestic flights as well as long international flights and they work wonders. They are on ear noise cancelling headphones and therefore have a higher clamping force on your ears so if you have sensitive ears cartilage these may not be for you but when compared to the over the ear designs, these provide pretty good noise cancelling. The feel of the headphones is very premium and they can work either with or without the noise cancelling enabled but I believe the sound is not very good with the N/C disabled. When enabled the sound is very good and does contain a little overly emphasized lower/mid end for the feeling of more bass. This price is extremely good for these headphones and I would buy these in a heart beat if I was in the market for N/C headphones.
