What did you guys think about the -3db Q=4 filter at 213Hz?

If I were to filter it would be 250Hz (Q=0.5 to 1.0) -2 to -3dB but don't think it is essential as it removes some of the warmth/fullness.
Treble needs to be lowered but this is better done with felt/toiletpaper than EQ.

I have not filtered just this range but made all the adjustments amirm suggested. However. I listen to rather low volume, so any distortion in the 200-300 range is hardly a problem anyway.

Pretty much all headphones have their mods & tweaks...
TP is seriously underrated though, not only can you use it to clean yourself and others, you can also use it to start a camp fire, as an attire or simply as decoration, and even in desperate situations, chewing gum. You can never have enough. When the great cough panic of 2020 hit the streets, what was the first thing to go? What were people most desperate to get their hands on? Was it food, ammo, water, masks, tissue paper? Nope... It was toilet paper.
I know Dan Clark also includes some in some of their kits, and it would be pretty cool if others did too, couldn't be too expensive. Slight tweak of sound as per user preference. Just make sure to use TP that has not been used for other purposes prior, as in my experience, it can get a bit messy.

I tried it. It doesn’t improve anything, IMO.

If I didn’t already have the means to correct it (Qudelix 5k), the TP is a brilliant alternative, but you already know that.
Well that is a funny line!

You know you've found a real high quality headphone when it needs EQ to really shine is just as funny and equally true for all headphones.
Here's the most funny part though.
Fortunately materials like paper, silk and felt and oam are quite common in front of headphone drivers (and not just as dust/hair guard) and lower resonances in a better way than EQ does.
EQ does not address change the resonance but only lowers the effect of the resonance by applying a lower stimulus.
Of course GaryH knew this as the toilet paper trick is well researched and a very old and proven trick.
But yes, it does need some taming of the treble as the S5X is not intended as a hifi headphone.

C'mon on now, putting sheets of toilet paper in your headphones has a lot more comic value than using EQ, I'm not saying it doesn't work (albeit I'd rather use EQ as it's more precise in terms of you know the exact effect), just it's funny when you combine it in a line like GaryH did in his post!

Its the word 'toilet' that made it funny... I know. The same line above is just the (sad) truth or...

Nah... needs the word toilet...

I don't disagree, but I've applied a -3dB adjustment at 3100Hz with Q=2 and that does the needful for me. It could probably be tweaked a bit, but I'm happy with it as is.
It was the word toilet, but also imagining cutting out a section & putting it in there. On a more serious note, I suppose not all toilet paper is created equal!

Indeed toilet paper certainly isn't all created equal
so I always specify the type and amount. Also one can sometimes use something like coffee filters but do not have the exact same effect.The recommendation to try it with toilet paper is because it is always around and most people buying more expensive headphones usually do not buy the cheap 1-ply toilet paper.
The fun thing is you can easily try this, cut to size (very delicate plies) and vary the amount at no extra costs.
Then one can either keep it in there or buy some felt which does a similar (but not same) thing in the correct thickness for better longevity.
OLLO themselves used a silk screen in the S4R and S4X which also had a similar (but again not the same) effect.
It usually works better than EQ because it not only affects just frequency response but also creates damping which EQ does not do.
Especially when there is 'sharpness' between 8kHz and 15kHz which is impossible to spot with industry standard measurements but can be there and cause listening fatigue.
That said, toilet, damping or coffee filter paper or felt are not always the best solution. This depends on many things though. In a lot of cases EQ actually works better because, as you say, it can be targeted. However, in the OLLO S5X the felt I use is clearly superior to any EQ I tried during experimenting and filters I made.
Toilet paper also works great but as it cannot sit 'firmly' between the metal frame and pad so felt is a better solution but... the effect can be tried with toilet paper.
You probably have read THIS but those who have not may find the toilet paper experiment interesting.

This reminds me of a documentary I saw the other day about Danish jazz guitarist Jakob Bro. During a recording session in a studio in New York, saxophonist Lee Konitz took part. He put a dish-cloth into the saxophone, because he wanted a less sharp tone with less intrusive overtones. Konitz could have said, you know you have a good saxophone if you can get a nice tone with a dish-cloth stuffed into it.

I went and got some 1mm thick felt to replace the toilet paper mod. As could be expected, it has more damping effect.
It's worth a try for everybody. Even if you like "detail" I don't think too hot treble actually brings any, it actually hides some when there is already a lot of treble in a song.

To me it was not obvious to use the felt mod. I liked the very detailed sound from the non felt-filtered SX5. But in the end I stayed with the felt cause I think it prevents fatigue. However. This is just me. I don’t know, my hearing in the high frequencies may be different from yours or others.
I think I can hear between 15-16kHz depending on the day. And as I said the extra treble is not too bad for some songs but when there is a lot going on in upper range then it sounds like a mess without the mod. For me it's better to never have that experience and miss a little bit most of the time. And then again maybe most would have a bit more detail 80-90% of time and stomach the occasional "oh man, too much"-moment.
