If anyone's looking for a pair of wireless headphones and doesn't mind spending a few bob, I'll just give a shout out for these fellas, which are phenomenally good. (You don't have to take my word for it, they've won all the awards.)
Sony WH-1000XM3Amazon are currently knocking them out for £244 (reduced from £330). I felt like a bit of a twat spending that much on a pair of headphones, but five minutes wearing them and I was satisfied they were worth every penny.
The noise cancelling is eerily good, they go plenty loud without any distortion with wonderful sound quality across all music genres, the app is slick and everything about them behaves itself perfectly.
They are basically just for use with a phone though, (which I knew before I bought them), you can't do much with them without the app and Bluetooth pairing, although there is a 3.5mm connector if you wish to go down that route.

They're under £230 now which is getting to justifiable... But the xm4 is out and apparently is significantly better again at noise cancelling. Also the XM3 don't really sit too comfortably on my head, sounds like the bigger cups on the new ones will help. But of course the new ones are £349 which is just stupid!
