Hey Fidelio X2 crowd, been having some issues and wonder if anyone could help me.
Basically, I've had two X2's with the same exact problem, and I don't know if I should get another replacement or something else is causing this issue. The issue being that they sound unbalanced, and the left ear sounds heavier. It's very subtle, but when I switch my headphones around, the heaviness stays on the left side of the headphones, not my ears. The effect seems to be most noticeable when it comes to vocals and low bass. The effect becomes most noticeable when I set everything to mono.
I can also prove that it isn't my ears, because when I use a tone generator and generate a tone between 30 and 150Hz and listen to each side from the outside, I can hear more vibration coming from the left side. I've tried the headphones on five different sources with the same result. I've used other headphones and they do not have the issue. I've done blind hearing tests where I will close my eyes and try to balance the headphones and I always end up setting the balance to the right.
I find it very hard to believe that I've gotten the same problem twice in a row, although it could be possible. Still, just the fact that I haven't heard this issue anywhere on the internet for these headphones and I just happen to get the issue twice in a row is really making me insane. There are plenty of people who have posted reviews on these headphones with no issue existing, and these are people who would probably notice an issue like this right away.
Should I go ahead and go for a third replacement, or is there something else I should look for that is causing this problem? I'm honestly starting to consider it's my own mind and that I am really just insane.
So yes, in some songs I also noticed left channel sounding a bit louder. Is it a problem with the driver or the pad I wonder? Or am I going insane too?
