Wow. Here is an update that has made a world of difference not only to the audio side of things but also my monitor's image quality.
This may also interest those who suffer from input latency related issues because I noticed something in that area too (I know input latency threads are more prevalent and talked about in this forum).

My computer setup is in my living room. Plugging extension cords/power strips to my living room's empty wall sockets makes a ridiculously good improvement to the clarity (and quality) of my audio, and vividness, motion smoothness and pixel clarity of my monitor.
The image is more vivid and things just pop out more on my screen. The biggest difference that I also notice now is actual depth in the image too which I had no idea my monitor was capable of displaying.. or I have lived in this apartment for too long and have gotten used to everything sounding and looking worse than what they actually could sound and look like.

I didn't expect that to happen at all, but I noticed the image depth thing right off the bat when I started going through the first 2-3 levels of Doom 1 every time I test my audio. And the audio too: the fact that it comes to me automatically now what the direction, position and distance of sound sources are, is telling that something happened for the better. I can almost visualize the sound's outlines around my head because of how clear and in focus the audio sounds now; it sounds like I am in the actual environment of the game and the enemies' sounds originate exactly from their position in the level on my monitor.. it's almost physical. That's how crazy of an improvement this is.

To make sure this wasn't a fluke, I have shut down and started up my PC several times, and it persists after days. In my head I instantly "realize" that it still works when I hear audio or play through a level in Doom and notice the depth in the image. There are many things I have done in the past which I thought helped but later realized they really didn't help in the end.

Now, what happens if I take out the extension cords? The audio is back to sounding almost hollow and flat which I was used to and thought it sounded good until I stumbled across this improvement. The image of my monitor no longer has the depth to it and lacks the pop, color and pixel clarity. There's nothing about it that I can easily put my finger on.. yet I can now notice that my monitor has also been lacking something this entire time.
Even the monitor, just like my headphone audio.. is able to show less of the same kind of "clarity" because of the interference.

This improvement lasts as long as I keep the extension cords plugged in to the wall sockets. The more extension cords I plug, the more it helps, so I have plugged an extension cord into every single wall outlet socket in my living room. This also applies to my kitchen's wall outlets. I could plug in anything else too, not just extension cords, but I felt that the effect wasn't as good.

The strange thing is that it takes a good 15 minutes to "settle". I can notice an immediate improvement in both audio and monitor image quality after turning on my PC, right after I have plugged in an extension cord, but I need to wait around that time for the effect to be at its strongest. I'm really curious to know what's happening behind the scenes. It's as if these extension cords are acting as cleansers.
Very good results. Can you make several recordings for comparison ? We have already many text messages in these forums, but only several good videos exists with proofs of not our problem

You can also record audio and compare both tracks in Audiocity

how many extension cords you use?
Do you think that the length of the wire affects the noise dispersion, or the number of extension cords?
What brand of extension cords?
Maybe the socket you are connecting to is "correct"?
I have 6 extension cords plugged into 6 wall sockets in the living room and 3 in 3 wall sockets in the kitchen, so every available wall socket in either room.

I don't know if the length of the cable matters, but the number of extension cords is the most important part in this case and matters the most. The more extension cords are plugged in the better, like the piece of a puzzle falls in the right place, and also unexpectedly makes a difference to my monitor's image quality.

The brand has no relevance, any extension cord works. Like I mentioned in the post, you don't have to plug in an extension cord. You can plug in a phone charger or anything with a power cable, but the result may not be as good. I think this may have something to do with electricity flowing out of the wall, through the extension cord and back into the wall, the electricity "completing a circuit".
I don't know for sure so I'm only guessing.

Yes, I have recorded both audio and video.

I used my phone to record everything because it's fully disconnected from the electricity, just like me. What I can see and hear is what my phone should mostly also see and hear, though that's really up to how good the camera and microphone is in the phone.
I recorded two short videos of me playing the first level of Doom. I tried to be as consistent between the two recordings, before and after plugging the extension cords. The position of the camera was in the exact same spot both times.

For the audio, I used the midi version of Doom's E1M1 for reference. I recorded the audio directly from my headphones by placing the phone's microphone in the middle of my headphone's earcups. I started recording the audio about 20 minutes after I had unplugged the extension cords from the walls, and then left the phone recording there. After plugging the extension cords in, the phone was still recording in the same spot between the earcups and then I waited another 20 minutes and played the midi file again, and stopped the recording. Nothing else was touched or moved during the entire recording, just the extension cords.

Here is a link to an archive I uploaded of the recordings, there are 5 files:
before.wav - Before I plugged in the extension cords, just like I described above
after.wav - After doing so
both_comparison.wav - Both files merged: left channel is before.wav, right channel is after.wav. I did my best to synchronize them so you can compare the differences
before_doom1gameplay.mp4 - "Before" gameplay of doom, for monitor image quality.
after_doom1gameplay.mp4 - "After" gameplay of doom, for monitor image quality.

Play the before.wav and after.wav sound files back to back and listen through them both fully, else it will be harder to notice what changes. You may need to keep listening over and over. They both sound quite similar, but there is a difference. You should notice that it's easier to "identify" each instrument and their position in the after.wav file.
Again, I used a phone for these recordings so what I hear and see won't come through in the recordings nearly as well as in practice.

Days and days have passed, and the audio and image depth improvement hasn't gone away. I still can't believe how much this has transformed the image quality of my monitor and the audio clarity/focus of my headphones. They're in perfect audiovisual agreement now, much like how I remember the headphones sounding when I tested them at another place. In this (my) case, the extension cords are the fix.
It looks silly how there are extension cords plugged in everywhere and nothing connected to them, but I'll gladly pay that price if that's what it takes until I move out from this apartment for good.

The interference that radiates over the air from my living room's grounded radiator and water pipes is reduced more and more, every time an extension cord is plugged into a wall outlet anywhere in the apartment. I remember reading once how in old apartment buildings in Europe everything is grounded through the radiator, or something along those lines. Maybe there is a connection.

The interference affects my phone's and television's performance just as much as it affects my PC. It affects all electronic devices.
I noticed this even in the background keyboard&mouse clicking sounds in the recordings I posted above; the clicks sound physically closer and more real in the after.wav/"After" Doom gameplay.mp4 files, even when the phone was not connected to the electricity in my apartment.
It is 110% a crosstalk issue caused by the interference. It reduces the ability to clearly identify and separate sounds/sound frequencies from each other, and makes the image of my monitor dead flat/less vivid and clear with no perceivable depth to it.
There is almost a dolly zoom-like effect in the image whenever I plug extension cords in; the image depth and clarity very subtly and gradually increases, it's disorienting.

I thought the interference only affected the living room and kitchen's outlets, but it reaches even the bathroom's outlets.
Every single wall outlet in this apartment needs an extension cord, even the hidden outlet which my refrigerator was plugged into.
Go figure.

Been lurking here for some time again.
Started seeing this interesting theory about leaving sockets empty like the lamp ceiling thing.

I bought myself one today i had 1 empty for 4 years and boy was I suprised. Mouse is freaking pin point accurate now.
My only problem is that somehow? My keyboard became somewhat slower.
I also noticed it was mentioned about using power branch outlet so I bought myself 6 of those and started connecting them without anything on the end. Only 3 empty sockets on all 6.

This is the weirdest shit ever.
Everything feels diffrent. Mouse is clean AF but keyboard is some how slower.
I than disconnected everything I just bought.
Keyboard is better but not fully functional as it is during "perfect nights" PS (that rarely occurs) but we all know right?

Mouse is than not perfect but also not "shit".

I can run Rocket League on 2k fps but i prefer 240.

PS nothing in my pc, monitor or periphials is broken or damaged. It all works fine in another location. Doesnt matter if ethernet cable is connected or not. Or by using wifi. I have probably the least jitter Chief has ever seen in my connection.

Some how tho this outlet thing or ceiling lamp dos something extremely weird? What did that dude say? The Circuit is now complete? We might be on to something here.

These are only temporary fixes. Because this shouldn't happen. Something is seriously wrong with your apartments.

I just have to ask. Do you have cable TV/internet?

I know Manmademan have.

This is only for those who have cable TV/internet or satellite TV. Not for ADSL, VDSL or fiber.

Buy termination caps for all unused sockets. They cost like 1€ a piece.

What is MoCA filter?:

It should be installed at the first point of entry. But I "think" it can installed before the modern too. I have VDSL2, so I am not sure about this. They cost like 20 - 30 euros.

I have fiber into the apartment which later goes via CAT5E into my apartment.
But it still changes everything wether its suppose to or not.
Still has a major impact

I believe you. It just does not make sense.

I reshape my question again.
Do you have cable TV or aerial TV?

If you have cable TV, you should block unused sockets with termination caps.

had exactly same issue with sound with both HD800s and Utopia 2022. the sound was shit with different soundcards,

GSX1000 USB
eCLARO HT OMEGA PCIe I even replace the AMP to expensive Burson V7 Vivid
Creative X4 USB
Creative SXFI AMP
Asus Xonar MKii USB
Chord Mojo2 USB
Z8 EverSolo DAC/AMP

everything sounded like hollow mess. somehow after I did many things the sound improved
On the mobile phone when I used the Chord Mojo2 it sound much better. the farther I went from the PC with the headphones it sounded better. the more close I was to the computer case there was like echoing shallow muddy sound at least more on the left side where the closer to the headphone.

Somehow the issue disappeared or improved a lot, but it's not perfect.

Since this apartment building was built in the early 70s, the only coax sockets in the entire apartment are the TV and Radio sockets in the living room. I also use an Axing TZU 21-65 TV/Data coax splitter which both my TV and internet router coax cables are plugged into. In this case, where should the filter be placed? Straight into the wall? To the TV/Data coax splitter's "Data" leg?

I also read that since the actual TV/Radio coax wires coming to this apartment inside the walls are "chained/chain installed", because the building is old, the coax cables continue from another person's apartment in this building to my apartment, and continue further to somebody else's after mine, installing a MoCA filter might cause signal or interference issues further down the wires, in the next person's apartment.
Is this something to consider? Then again, to put this in videogame terms, all this is level 100 information to me and I'm level 1.
The only MoCA filter I found is on Amazon, is this correct?

If the Mojo is battery operated, it definitely should help by not being electrically connected to anything else.

There's such a thing as unbalanced and balanced audio gear (the DT 770 headphones I use are unbalanced as is my Fiio K5 Pro).
I wonder how much balanced audio would have an impact in this case. Balanced audio by design would cancel out any outside interference from what I remember reading.
