I imagine buying headphones must be like buying a bra for women. I've found that taking other people's advice about headphones is utterly useless, as different ears and brains hear differently, people have a different picture in their mind of "what good sound is" which alters as you age. It's a flustercuck it really is. I suggest you listen to as many cans as you can and make a decision. This is a journey you should make alone for best results.
Also remember that your DAC and amplification matter, especially as you go up the price range of headphones. If you're listening in store you're probably listening to a premium HP amp. Always keep that in mind.
