I have a big head (hat size 7 3/4). For me these headphones are a bit tight (hence 4 stars instead of five) but not so tight as the Apple AirPods Max which I returned before ordering these. In all other respects these headphones are excellent. They connected easily to my Macbook Air over Bluetooth and the connection has been reliable for the two weeks since. The noice cancelling cuts out enough background noise like washing machines and passing cars for me to be happy. The ANC background hiss is very minor and is masked by playing even very quiet music. The sound quality is, to my ears, better than all other closed back headphones that I have tried over the years. It seems generally clearer and more detailed. In particular the sense of space and not being "locked in your head" is very good with these. Recommended for anybody who is smaller than a size 8!
