Headphone, dac, amp and mic purchase advise

Hello guys, I currently have a HyperX Cloud Alpha headset and it has served me very well, but I feel it’s time to get an upgrade.

I’m looking for a combination of headphones (closed or open back), mic, amp and/or dac. The mic can be built into the headset, and an amp or dac is not a requirement if for example a pair of really good headphones gives me a better experience than some cheaper headphone+amp/dac. I’d prefer to keep it at about 350 euros, but I can go over if there is a really good option.

Sound quality is the highest priority. The headphones will be used for gaming and listening to music/movies on my computer. I listen to many music genres, mostly metal, funk and jazz. I really like bass since I’m a drummer so in music I pay special attention to the drums and bass guitar.

Comfort is the second highest priority since I use them for several hours a day. I have a medium sized head and ears (I think). For reference, the HyperX Cloud Alpha is a good fit.

The mic is not so high priority. It will probably be a built in mic since that saves money.

I’ve been looking at the Arctis pro+gamedac combination, but I’m not sure since I’ve not heard so good things about the quality on gaming headsets. You guys probably have something better to suggest.

If you need any more info to make a suggestion you can ask, and thank you in advance for any help!

Thank you very much for your response, though I already went for the DT 770 pros.
