I thank you so much for your support and patience.
Actually im reading into this topics about the Harman Curve and build some EQ Settings with Pro-Q and the 1.41 factor with the values from
nctechno

I´ts definitly better than the original sound from the Headphones. And i start to think, that this is also better than my Custom Target in Reference, because i maintain more details in the highs, without beeing too harsh. Lowering the 10.000 is the key for my ears.
I also start to test Can Opener.

I Found this video, but i think it was also posted in other threads:

I continue some experimenting with The Harman curce and Can Opener and need to compare this with the Reference Solution, because they really sound complete different. And i need to trust one of them ^^

The last piece of the puzzle would be A system wide VST Plugin container, where i could use Can Opener, while listening to Youtube or other web sources (I know, its not the best referencing practice )

Short Question here:
Would you do the Can Opener before or after the EQ Correction?
I read some differrent opinions.

I asked the AI, maybe that will help you:

1. Can Opener Before EQ Correction:
   
   • If your headphone EQ correction uses asymmetrical profiles for the left and right channels (e.g., Sonarworks with custom calibration), placing Can Opener first ensures that its crossfeed algorithm works on the uncorrected signal, avoiding potential interference with the EQ adjustments.
     
2. Can Opener After EQ Correction:
   
   • For most setups, Can Opener is recommended to be placed last in the chain, especially if you're not using its built-in dithering. This allows it to simulate speaker-like listening after all other corrections have been applied.
     
     
   • If you prioritize maintaining the integrity of your EQ correction (e.g., Harman or Sonarworks curves), placing Can Opener last ensures it doesn't alter the frequency response adjustments already made.
     
3. General Rule:
   
   • If dithering is enabled in Can Opener, it must be placed last in the chain.
     
     
   • For linear processing setups, the order matters less, but Can Opener should generally be near or at the end for optimal speaker simulation effects14.
     

Ultimately, trust your ears and experiment with both orders to determine which setup aligns best with your preferences and workflow.

 

OK. You helped me a lot my friends.
Now it's my turn ...or the turn of my ears ^^

Will report how it's going the next days.
Have a good time

EDIT:
Played around 3 hours on my Windows PC: EQ APO Can´t handle the Canopener VST. It´s a known bug.

Got it to run in 5 Minutes on my Macbook with Soundsource. --) What a powerful tool !!
Chain:
Pro-Q to analyze frequencies on every playback (Browser, System, etc.)
Pro-Q Harman Courve for my DT 700 Pro X
Canopener (Mix Engineer)

Sound is really transparent now and not harsh anymore, but i think i don´t loose so much frequencies like in Reference.

I also appreciate your hints, to make Pause after short while.
I think i really need to make pause every 30 minutes. Than my ears are fine

you can use the impulse responses and any convolver too thats very convenient and fast to switch to another curve

have to correct myself FF is Q times 1.41 not divide 1.41, what most EQs display as 0.71 is 1 in FF

i don't know what target sonarworks is using, but i tried them myself and i strongly believe they use some kind of diffuse field like curve because i remember very lacking low end.

after my adventure to the site i'm now using the average of the slider peq results and the harman curve

 

I hope I made it right in Pro-q. ^^
Yesterday I played around for hours and my ears didn't bleed. So it seems to be working.
I can also upload a screenshot later.

 

I had exactly the same issues with my 900 Pro X which I was also using with Sonarworks. I had two problems, the first was the fatigue probably due to the slightly harsh high ends and the second was the clamping force of the headphones, the latter lead me to developing eustachian tube dysfunction which took me a while to realize that the headphones were actually the cause rather than allergies etc. I already own HD600 as an alternative but in the end I decided on buying the HD490 pro. These are super comfortable with very smooth tops and better bass response than the HD600. As a result I also ditched Sonarworks when using them. I would highly recommend

 

Sometimes, harsh highs are in the ORIGINAL mix/mastering.
Electronic genres are concerned, because they compensate a lot of bass by more highs.
And sometimes ... too much.
So hearing it is a GOOD quality sign.
Mixing headphones are NOT meant to make you "enjoy" music.
They are here to be accurate.

If you want to simply want to "enjoy" music, it is different.

You can put some NON aggressive micropore tape directly on the speaker grill, just under the pad.
Paper can work too.

try putting ddmf metaplugin in APO and then put canopener into metaplugin. might work.
