I would suggest the Sennheiser HD 65 TV, I have this thing for years. I have a microphone on the side because the headset has none. But it has impeccable sound.

How much do you want to spend?

Do you want just headphones (with a seperate mic) or do you need a headset with one built in, headphones will sound better for the money, but, you'll need to get a mic (10 bucks off amazon would work).

Finally, do you want closed or open back headphones? Open give a bigger sound stage, but less bass and no sound isolation, closed will generally have more bass better to amazing sound isolation but a less 'airy' sound stage, most (all?) headsets are closed back and if you use the mic a lot, closed tends to be betterso your mic won't pick stuff up.

senheiser is good but no longer available for me since they got taken over unless i want to pay twice the price due to import costs

the one i would recommend for budget is the philips fidelio x2hr most of its build is metal it has a detachable cable it is a open back headphone but even though that normally effects the bass these even beat a lot of closed backs in bass i know because it took me a while to find closed backs since i want both

i also now have the beyerdynamic dt 700 pro bass is great better then the philips which you should expect from a closed back but they are known to be very harsh on mistakes in mixing of music which some people just do not like but for me that is perfect

as for build quality they look worse then the philips fidelio x2hr but they are fine the cable you mention is not proprietary they are just xlr cables and you can purchase any xlr cable and be fine this is the standard for professional audio work which wel is what they are made for studio purposes the philips ones are entry studio headphones

but yeah they come with a price tag not horrible and the sound is great if you do not mind the harshness i mentioned you can literally hear everything clearly separated from each other

there is a alternative but the build quality just aint great while the bass is rated as one of the best which is the FIIO FT1 but yeah its questionable how long they last which heck they should have made it 200 euro and improved the build quality and i would have went for that one over the beyerdynamic

there is 1 note though about the beyerdynamic dt 700 they are build to handle higher volumes so it takes way higher volumes before they distort they are also louder out of the box compared to many other headphones at the same ohm they are really easy to drive

I've had a pair of fiio ft1 from the release day and they have been great in both sound and build quality so far.

I was actually so impressed I ordered the fiio ft7 planar magnetics which are simply breathtaking (but outside of OP's budget sadly) and have their new k17 dac / amp on the way.

HIFIMAN has some great offerings too and both hifiman and fiio can be gotten notably cheaper if you buy them through aliexpress and don't mind waiting on delivery, I saved £350 on the ft7's and nearly £300 on the k17 for example.

You might not like this suggestion but here goes anyway.
I suggest getting cheap but good IEMs. There are a few good ones around now for
a much cheaper price then what equally priced headphones can give in sound quality.

I have a Audeze maxwell headset $300.00 USD here in OZ they they were $500 and they sound very good, a little heavy on the head but sound great but I still prefer to use IEMs that cost under $100 If I am using them for music and gaming without chat.

The huge downside of these is if you plan on using a microphone too,
I just hate speaking with the IEMs in my ears.

Edited the post. No mic (although most have them integrated with a tiny hole so, oh well in that case. I can just deactivate it), open or closed doesn't really matter since I'm separate from others in the house, and I can go up to 200 euros big max, though I'd prefer not to pay that much unless the cable can be easily replaced.

Then I can highly recommend the fiio ft1, comes with a spare cable, can easily buy more, sounds good and great value at around £140.

If you are OK buying second hand, it will open up some better headphones, my main headphones are a pair of shure srh1540's I've had for years and are my go to for gaming, new they are around £500, but can be found second hand at around 150 to 200, again, you can easily get all replacement parts.

Infact, second hand can really get you a bargain, the step up from £200 to 400 to £500 headphones is noticeable and they pretty much all have easily replaced parts at that price point and they very often show up for a bargain used, worth considering perhaps.

But, if you want to stick with new, the fiio ft1's are great.

Good luck.

Edit.
You can get the ft1 in open ir closed back, the ft1 pro is the open back version, the base ft1 with the wood ear cups are closed, very similar prices so it's more of a personal choice vs one being better than the other.

Bright or dark sounding cans? I believe you had stated you'd prefer ones with detachable cables? Sennheiser HD6XX is the only pair that comes to mind...for me anyway, a used pair can be had for ~150USD and less.

A pair of new HD6XX would be around 200USD, fits your cable requirement, but is an open back can. It's generally seen as a good starter audiophile can, and is pretty good for games as well....though some would describe its sound as being a tad narrow.

I'd be hard pressed to think of a closed back can with detachable cables though, I don't dabble too much with closed back having 2-3 closed back cans in my collection. Maybe a Fostex T50RP MK2/3/4?

Hmm. Those Sennheiser are 300 euros where I'm at. I see a 599 for a 'mere' 120 though.

you can always check the senheiser hd 58x jubilee as a alternative unless they are also near that price

check if drop.com which was massdrop before ships within your country they are the ones that took over senheiser

if not you are in the same boat as me and have to find alternatives or pay a hefty price knowing full well that at that price there are likely even better headphones available

I really like my Audio Technica studio monitor earphones - forgotten what model but similar to this:

Note the detatchable cable. The sound is wonderful.

The sound. It’s all abt the sound. Demo the headphones and pick the one that sounds the most pleasant to you.

No chance at doing that nowadays.

Personally I am a fan of Sennheisers.
Currently have a HD 599 and I really like it, probably one of the best options around that price range IMO.
Have an old pair that were some kind of HD 5XX that I really liked too and still use after well over a decade of use. Sorry I can't remember the model number of that one, but they were $70-100 back in the day and were discontinued.

Headphones are pretty subjective, but if you get any of the decent-quality headphones you will absolutely blow away every dedicated gaming headset out there.

sometimes you can get the black amazon variant for that, it's great deal.
