Seeing the wires version of these on sale for $99 in the US Newegg and $148CAD is Canada Visions Electronics. So was tempted buy a pair. Fortunately I was able to have a trial listen in store. Bottom line for me was the ANC impacted the signature a lot so only good when really needed such as a plane or transit. But ANC off these sounded pretty amazing. But just a bit to forward in the midrange for me. If you fly a lot these would definitely give you the best audiophile sound possible, much better than Bose or Sony in this regard. But if you dont need the ANC and already own the M500 or the NAD5 HP50 then I think these are to similar to justify buying. Comfort wise the ear cup is slightly smaller than the NAD HP50 in the opening but is wider so close to the same comfort. In other words just OK not great. The lack of s proper smart phone cable is a complete miss by KEF considering these are meant for portable use. Unfortunately KEF made enough gaffes like the cable to probably kill any chance of these being popular which is why they are being sold at such a low price. But a cheap after market cable can overcome the cable gaff and at their sale prices your never going to get a more affordable audiophile quality ANC product. That sounds even more awesome when you turn off the ANC.
