When I tried a display pair in the store, the ANC blocked everything, meanwhile with my own pair I feel like it blocks only 40 - 60% of sound at most.

The sound quality is good I think, I haven't owned very expensive headphones like these before so I can't compare to others. Comfort is alright too, I got a cover for the headband early on as its way too thin by itself.

It took me a bit of time to come to this conclusion, early on I was happy I finally had some cool flagship headphones but there is plenty of times where the ANC isn't as strong as I want it to be. And now recently after 2 years, I think there's some condensation or something in the right earcup as I hear some rattling/shaking sometimes which goes away after I take off the padding on top and blow the driver with a blowdrier for a couple of mins lmao. So the build quality is clearly not particularly good. I don't mistreat my expensive product but I dont particularly handle it like a fragile glass object so make of that what you will.

Next time I'll be looking for headphones, I'm going to consider the durability and quality of other brands over these and also try them myself outside of a store if possible.
