Bowers & Wilkins PX are a solid alternative to Bose/Sony and similar price range. If you want to listen to silence or audiobooks then the others have a stronger cancelling effect and will probably suit better. But if you enjoy listening to music I found the PX is more subtle, with 'just enough' NC that it does not compromise on sound quality but still removes annoying environment noise. I have flown with them a few times now as well as the QC35 and prefer the PX. The build feels better (a little heavier) and has the same nice features like fold flat and removable cups. I think they will hold up well with travel abuse.
