I have compared them to some of my other headphones and sure there is a difference between these and my other larger headphones (HD 558, ATH M50x, Momentums), but these are also cordless, on ear, and cheaper and by no means lacking anywhere near enough to not justify their price or purchase. Momentarily drops the L-Button when being held down. The only improvement I would add, is the use of some plastic in the upper area; would better use of metal throughout, to ensure greater security. The noise cancellation is excellent and you can set them to high, low and off levels. a big) so they look good on your head too. I have not been able to test the 100 hours of battery yet, but I have not had to charge them at all for over two-weeks and I use them daily. Excellent and ten pounds cheaper than in the shopd With this one, I should have ordered a medium at most. You still get full 4K, HDR even game enhancer but again no Freesync. Looks good, even better than just the raw end of AZEK boards.
