I should start by reiterating that Sony's WH-1000XM6 are good headphones. They're the whole package — solid sound, excellent ANC, and a comfortable fit. I'm not really even sure if Sony is capable of making bad headphones, but some issues hold them back from a full mention on our best headphones list.
I'm not going to go into detail (yet), but they aren't enough of a step up from the old version to make much sense if you're an XM5 user. Sure, there are some nice extras and improvements, but not enough to justify buying a completely new pair of headphones.
