Looking for a new basic headphone setup (under 500EUR if possible)

Hi,
I'm new here but not new to audio in general, and I have quite a bit experience with different headphones and IEM's.
I also have significant hearing loss and I'm 44 years old. I'm also a mechanical engineer.

As smartphone manufacturers started to get rid of the mini-jacks, I went LG V30 and then Sony Xperia 1 mkIV. I'e also purchased a very nice Korean BT device, but it unfortunately had broken down.
Nowadays I use mostly my WF1000-XM5's and I find them very pleasant, but I'd like to also have "true" headphones (or IEM's).

In the times when I still used wired headphones my favourite were UE Triple.Fi's due to very good price/performance ratio.
I never was a big fan of large headphones, I always had issues with finding something that sounded even close to IEM at the same price point.

The impulse that led me to writing this post was listening to DT770Pro's (250Ohm variant) which I borrowed from a friend.
I've connected them to my laptop (Precision 7750) mini-jack and...
I'm apalled. I was expecting sub par loudness and artifacts, because it's a laptop hole, but I haven't expected that they will sound like somebody dropped them into the well.
I double checked with my SO and she told me (after maybe 30s of listening) that they "sound like closed in a metal box).
Those headphones are well regarded and not exactly cheap (around 200EUR).
Therefore my question is:
1. Which wired headphones or IEM's will have good sound quality under 500EUR? Possible closer to 200EUR as I also need to buy some device that will allow me to connect to my laptop/tablet smartphone and supply the optimal amount of power to the headphones, and allow me to take calls in the same time? I belive thats something like a Fiio BTR17 would be optimal (if not made in China).
2. I'd prefer for it to NOT be made in China. I'm trying to avoid Chinese products if possible.
3. I like to have as much isolation as possible, so IEM's and closed back headphones are preferred.
4. I have a taste in music that I'd call "eclectic". I'm listening to electronic music (from Jean Michelle Jarre to Combichrist), folk (Wardruna, Dead Can Dance), rock, metal.
5. Headphones I had experience with in the past, apart from the Triple.Fi's: Sennheiser HD600, and HD820 (hated both), AKG k701 (hated them even more than Sennheisers), ATH-M50/M70 (very nice visually, but also incredibely harsh trebles), Meze 99 (very nice but ugly), lots' of Fiio IEM's (didn't like them, because of the open construction). IEM's that made a positive impression were: Kinera Nanna, Triple.FI's, and CustomArt Fibae (all of them, but lower models had tuning that was less "audiophile" therefore nicer for my ears).

I think Apple AirPods Pro 2 or 3 should be your first option because they can compensate for hearing loss. If I'm not mistaken they can help with hearing loss up to 55db HL, but I read that people with 60db HL still found them much better sounding than their very expensive hearing aids that can't play low frequencies. As a hearing aid they are mediocre but as far as playing music with hearing loss they are supposed to be the best.
If your hearing loss is not that bad, and within mild range and a simple increse in volume brings enough clarity then you can try Audeze Maxwell 2 closed back wireless headphones, they are more or less Harman tuned (neutral sounding) and also have built-in EQ to adjust to your taste, but with hearing loss a simple EQ rarely helps.

I don't think that my hearing loss is that large, and also I boycott Apple products because of their anti-consumer practices.
As I'm 100% Windows/Android person (for work-related reasons), I find buying Airpods, which are at least in part incompatible with my ecosystems of choice counterproductive.
As for the Audeze Maxwell 2 - the design is okish, but they are marketed as "gaming" headphones and I don't game, so I don't need a mic boom.
Are they "mobile" in a sense that they can be comfortably used outdoors, in a public transport and with mobile devices?

The only issue with Maxwell 2 is its weight, 560g. The gaming features can be disabled and the microphone can be disconnected.
You can also try Austrian audio hi-x60 closed back headphones ($300), they sound very open and clean, but for some people there may be a bit too much energy in high frequencies after 4khz, so you may need to lower it a bit with an EQ if you will find the sound too detailed or fatiguing.
Apple Airpods can be used with any bluetooth device, you would need an iPhone or Ipad only to setup your hearing correction profile and then it is saved and applied by default. It will allow you to lower your average listening volume to safe 65-80db and prevent further hearing loss. Without hearing correction you can easily go over 85db and didn't notice it at all as super loud and damaging in long term if you don't suffer from hyperaccusis or recruitement, but it all depends on your individual hearing loss profile.
