As a frequent long haul flyer for many years I was grateful for my Bose QC headphones, but never ever let them near the audio gear at home! Having tried many, I have yet to hear any NC or wireless phones even remotely approaching 'hifi' quality. (Tbh, even as a customer that's where Bose sits with me for all their products - your opinion may vary.)
Based on this, I don't currently buy into the marketing, that NC = improved audio. Its a very different need. NC has it's place - on long (oh so long) flights, I found in-ear too uncomfortable and over ear too hot, so the 'on ear' Bose ones were an acceptable compromise, and useful when an 11 hour flight follows a 15hour working day.
Tech usually improves though. If they can pull off an Audeze-bothering SQ from active NC headphones like these, at a comparatively reasonable price then that's great. Til then, for me and I suspect like most who are into their audio gear, there'll be headphones for at home, IEMs for out and about, and maybe NCs for flying if the need is there.
If the recent Homepod is anything to go by they may well sound perfectly reasonable, but will be crippled and only work with apple devices as their source, at which point they will be immediately ruled out. Breath is not being held!
