I daily Sennheiser 6XX, thinking of getting ATH-AD700X

Hello, hope you are having a good day. I daily Sennheiser 6XX and I’ve been thinking of getting a headphone solely for competitive gaming and I’ve been looking at the ATH-AD700X, I’ve read about them a lot and I know they are pretty accurate when it comes to sound-staging but coming from 6XX will I be disappointed in sound quality or anything else? or will I enjoy them? I also know they are lacking in bass but I imagine that can be mostly fixed in eq? idk. that’s why I ask you kindly to share your experiences with me. thanks in advance.
