There is absolutely no contest between an open-back audiophile Sennheiser like HD600 or HD800 and any ANC headphone. I own both these headphones and formerly a Sony MX3. The MX3 is also beaten in sound quality by a Sennheiser Momentum 4. The default sound of the Sony was frankly awful, bloated bass (+5db) that bleeds into the midrange, almost certainly not what most artists intended. They were better with EQ, although still muddy and the built-in EQ didn't work with LDAC. So I never bought another.
The HD800 are the best pair of headphones I have ever owned. Incredible soundstage and imaging. They are probably the best anyone could ever do with dynamic drivers. I have a lot of music that I save for these headphones, never wanting to play on the go via Bluetooth.
My HD600 are still going strong (having been purchased in the early 90s), thanks to a quality product and availability of spare parts. Sennheiser are a fantastic company and I hope they keep making headphones.
