Looking to replace my game zeros (Sorry kinda an audio noob)

[Kyronami]

Been using game zeros for a while, love the headphones I just think its time for an upgrade. I tried the GSP600 and the mic was amazing and the sound was good... however they HURT to wear and couldn't have them on for more then 15 minutes before the sides of my jaw hurt where it clamped against my head so I had to return them. 

 

I also want to mention that my motherboard is the Gigabyte Z390 AORUS Master, And I also have the Creative Sound Blaster Zx PCIe sound card. I honestly dont even know what sort of headphones my MOBO can handle without any kind of sound card.

 

I was looking at getting either the 250 OHM version of the Beyerdynamic Dt 990 or the 770s, plus maybe the Sound BlasterX G6 along with it since I like having the surround sound type feature (which I know is a meme, but whenever I turn it off I just think my sound is so weird). I've never really used open back headphones before, I do like the enclosed noise canceling feeling of closed backs, but I have no idea how different the sound really is. 

 

Will the Beyer headphones be a significant sound upgrade over the game zero?

Is it really worth to get the open back instead of the closed? Is it actually that noticeable in audio quality? 

Are the 250 ohm versions noticeable over say the 80? (I don't really know much about sound)

Does anyone know if the SB G6 is actually an upgrade over the zx pcie card? 

Any other thoughts about the headphones and amp im looking at? Better options?

 

My budget is $400-600 if it helps any.. I plan to switch over to using my Yeti mic I guess since it seems most of the "good" headphones aren't actually headsets

HD6XX's and the DT 990's are always a good choice and they definitely wont break the bank. The best headphones ive tried in that price range are the Koss 95X. They are hands down the best headphones in that price and anything above it is really giving diminishing results.

I would say yeah a decent upgrade especially in the detail front. And if you look below this to see my setup you can see how much I like my opens. It's not that closed is bad I loved closed backs and am in the process of getting one myself  but open backs are indeed better for games and great for music. But if you need the isolation. You can probably find a better headphone for your budget maybe argons are a pick or the audeze Mobius the suround on that is pretty good as has weird motion tech as well. And just sounds good no dac amp needed as it a wireless headsey
