Help with picking first "high end" headphones

Hi! I’m considering buying some higher quality headphones for my desktop, and have no idea where to go from here.
I’ve been looking alot at Zeos reviews on youtube, and come to the conclusion that I would maybe like a pair of beyerdynamic headphones.
My main use is gaming and music, and a movie or tv show now and then.

My problem is that there is nowhere for me to try out these headphones nearby, as no store has them in stock around here.

I am considering between DT 770 80ohm or TYGR 300R.

My main focus is comfort, as I would use them in 4-5 hour sessions.

Is there any noticable difference in these for a non audiophile as myself?

I am going to run them through my focusrite scarlett solo (3rd gen).

Location? Budget?, What sound are you after? Open back or closed? These are all questions that you will need to think about and answer before you can have a idea of what you want. Also please remember what “he” likes or recommends may not be what you may like. Personally I have never agreed with “his” choices of sound. Other people here will ask these same questions so if you can post the answers then help will arrive much quicker!

Norway, budget is about $150-200. Have only used Closed back so far, no idea how a open back would feel like, although I do play in a seperate room in the house, so sound leaking would not be a problem.
No idea what sound im after, as up until this moment I have been using gaming headphones ( Logitech G35, Razer Manowar). I appreciate a good bass, but not an overwhelming amount.
