Headphone Stereo Image not centered!

[imDRAWN]

Hey guys, im an audiogeek from germany, 22 years old, experimenting with hifi audio for about 2 years now.
I finally convinced myself to make this post. This following Problem means alot to me both logical and psychological whise, because I am struggling with it for a very long time. 
 
 
So lets get to the point. When listening to Headphones, i do not get a centered Stereo Image. At the moment (and now it already gets quite hard to exactly explain this vage and illogical problem) MOST of the music is on my left channel. What does this mean? 
When listening to a stereo, surround or mono source, from all sorts of devices with different headphones, majorily low frequencies will be played on my left channel. If I play a Mono source at a moderate loudness, my left headphone driver is shaking, my right one doesnt even care.
 
 
The setups:
 
I have a normal CD Player here, cheap one but I get AUX out into my headphone amp FiiO Qogir E09K ->                       experiencing more bass on the left
 
I am at my gaming Desktop PC with an Audiolab M-DAC either connecting with USB, or SPDIF from my SB Recon3D PCIe -experiencing more bass on the left
 
I tried the Audioengine D1 with USB on my gaming Desktop PC ->                                                                             experiencing more bass on the left 
 
I tried both DACs (Audioendinge D1, Audiolab M-DAC) at my Laptop and my friends office PC via USB ->                         experiencing more bass on the left
 
I tested the Pro-ject Stream Box DS connceting via COAX to the Audiolab M-DAC ->                                                     experiencing more bass on the left
 
Finally, I tested just my mobile phone HTC One ->                                                                                                 experiencing more bass on the left
 
 
Usually this would mean the headphones are having a defact, but: all of these setups have been tested with:
 
1. Sennheiser HD700
2. Phillips Fidelio X2/00
3. Beyerdynamic T70 
 
So it could only be the music .I tested Ton´s of different tracks, from live recordings to EDM, from Spotify to FLAC´s and AIFF´s high quality soundtracks. I used different players from vlc to foobar and from AIMP to Winamp. I even noticed it at random youtube videos, twitch streams or any steam games. Finally i found audiocheck.net. I found a very simple test that shows that something is very wrong at my current state: http://www.audiocheck.net/audiotests_stereo.php 
Left is on the left. Right is on the right, Both channels is slightly to the left! (note that this is not easy to hear, since the imbalance is mostly when listening to low frequencies)
 
So this is where i started going kind of crazy. I went to the ear doctor but my hearing was perfectly fine, plus friends also told me that they hear the exact same imaging problem. 
I digged deeper. I found that the surrounding in my room will have an effect on my headphones, so i tested different rooms but that didnt help. I tested a "mains filter" that should erase all noise from other electronical devices in the house but that also did not help. 
 
Finally after powering up a blank mono source through the Audiolab M-DAC making the problem very very noticable, I came to this forum, out of ideas and inspiration to keep working on this. I read about this a litte in the internet. However this is too extreme to just say "its how the music sounds".
 
I am open to ALL kinds of advices or ideas. (If there is an expert out there. I am also available per mobile phone or email just write a PM.)

What low frequencies? Sub bass frequencies can be difficult to determine direction, so it could be you have convinced yourself there is a channel imbalance going on that is not there. Learn about expectation bias in audio and how powerful they are for making us hear something that may not be there.

Im not a headphone scientist or anything, when i say low frequencies im talking about the bass. You have to understand how hard this imbalance is. Its not something you hear only, you feel the driver shaking more. It is extremly noticeable. Everyone hears it too, not only me.

 

[cel4145]

Learn about expectation bias. If you tell people there is a bit of a channel balance in the bass frequencies, they could easily hear it even if not there.

this is why i was struggling doing such a post, you disrespect my opinion with saying that. why do you think if im serious about this would tell people beforehand where the bass is and not ask them afterwards for an objective opinion? saying it the way you do is disrespectful to me and all the work i did, take the problem please serious

Lighten up. This is not "disrepecting" your opinion. You said,

I am open to ALL kinds of advices or ideas. 

You didn't describe your methodology with how you had tested other people. How do I know how you tested it?

Also, according to sound science, double blind testing is necessary to prevent bias in tests which try to determine if there is a difference or not. Now if you want to discuss this kind of stuff, then take the chip off your shoulder. Don't disrespect those who are trying to help you

you still didnt get the point, what a disappointment. this is not about "oh i feel slightly more base" this is left side shaking in MY HAND more than right side. it has nothing to do with listening but with how they are driven by the hardware, so if you have no valid idea just leave me alone and stop wasting my time because you apprantly didnt even read what i said
 
to the others im still open for everything

The likelihood that all the equipment you list is presenting the exact same issue is infinitesimally small.
The liklelihood that Cel4145's advice about expectation bias is correct given the evidence you provided is overwhelmingly large.

The best way to pursue this forward would be to follow the recommendation given to conduct a properly constructed double blind test. I know you won't like this answer any more than the previous posts, but......

Have you reversed headphones? Do you live near a blackhole? There is the blackhole on Bogenstrasse in Nuernberg, Germany.

well, this is all i will say: It is not my hearing. 3 Reasons:
 
1. I was at the ear doctor and i hear perfectly fine.
2. I can reverse stereo channels in the player and the issue is still on the left side.
3. I asked varius different people, also a hifi expert from where i bought my Audiolab DAC and even he said after asking him if everything sounds correct, that the bass is not balanced.
 
If some of you guys still give awnsers into this direction, i can finally say that i had a reason to not go into a forum with this. 
 
 
Furthermore, this is an issue that goes deeper than simple fixing. I found somehting majorly wrong here and we should think about differences between the electricity in europe compared to the USA for example. Thats the only logical direction.

How do you store headphones?
Can you check resistance and inductance of both drivers of all headphones?

Always interesting when someone asks for help then rejects the answers because they don't fit their predetermined beliefs in the problem's root cause.

Do you really think you discovered an issue in headphone bass balance caused by differences in the U.S. and European power grids? And that none of the members here had noticed that previously? That's insulting, but when you get your Nobel prize for the discovery, come back and tell us off...

I usually leave them on the table, when they arent in their case.
 
Unfortunately havent had the opportunity to check with professional mesurement equipment yet, i am trying to borrow some somewhere. You said resistance and inductance. What exactly are those and how could it relate to my problem? I only know what impedance is, is impedance a result of them both?

So you really really, didnt read? See thats why people often turn away from forums like this.

I certainly read what you wrote. Have you read and actually considered what others have written?

Good luck solving your "problem".

PFaha, just leave this thread alone and stop bothering me kid.
