Looking for Headphones upgrade-something that wont increase the rate of my hair loss xD

I haven't tried that may IEM's. The Dunu Titan 1 are my favourite so far, but they're sort of semi open back. And the only Sennheiser's I've owned are HD380pro, which I did find extremely comfortable, it would be hard to guess what you'd find more comfortable than the game one.

Nice and comfy & excellent spatial sound detail for gaming. And the headband is a slim style so it won't mess up too much of your hair do. I love mine for FPS games personally.

In the end what you choose comes down to personal preference. I'd recommend trying on a few pairs at a local music store if you have one nearby.

which headphones? whats the model?

Sennheiser HD 650. Also might consider the lower cost black version of these same headphones, which are sold by Massdrop and called HD 6XX.

What is not comfortable about them for you?
Sennheiser can be OK in the 600+ range but that gamery stuff I would avoid along with below 600 unless on a budget and they fit your head and sound you want, like cheap 598SR or what it is, remade 598 in black for cheap.
Get a separate microphone, though I can understand what a royal pain that is same as choosing headphones, looking for a half decent microphone myself right now.
Super comfort... only you can test that, how deep cups do you need aka how much do your ears stick out compared to rest of your head curvature? For me I need deep cups due to my head shape so most headphones fail right away for me as they press on my ears. All the Sennheisers are shallow as far as I remember or not worth buying like that 800 disaster.
Headphone not resting on head would be a rear band headphone or in ears or around ears or something like that, there are maybe maybe some decent one from some maker.
Most decent headphones have a top of the head band, many are thin and stiff = not comfy, only some have memory foam, otherwise you have to DIY it like I did with a piece of open cell foam = that thing is pressure free but does not let heat out which can be undesirable, where as double HD600 pads dig into my head painfully with the 4 not so soft foam blocks.

If you can get memory foam padded headphones but sadly barely any have this for their pads and band. The unusable 569 I think had it, AT MSR7 I think is the name and AKG K712 Pro has pads only with a leather top band that you will definitely want to put a foam on yourself.

HD600 with an HD650 cable I would rate above HD650. They are not shaped for my head though and the pads have no depth. Soundstage is narrow on almost if not all Sennheisers unfortunately because the drivers are always so close to your ear.

Best thing you can do is go to a headphone store and try as many as you can, listen to them etc. Then buy/borrow the ones you liked most to try at home.

That Audio-Technica ATH-M50x meme really gotta stop already LOL. They are not good headphones for home use, they are not comfy, etc. There are some AT headphones that sound well but it's not the M40/50/70 etc. Was it R70x? Sounded similar to HD600. And then the "portable" "V shaped" MSR7 have their use. And some other expensive open ones.
