I suffer from slight, but constant, tinnitus due to exposure to high volumes for years playing and touring in bands but for a couple of years now I make sure to wear earplugs and keep the volume low. I take hearing-tests on a regular basis and the last time my hearing was, according to the audiogram, estimated at "normal". So I'm luckily still not in the "slight hearing loss" category.
Lately though, I notice that with every headphone I use I hear the vocals slightly off-center. They appear more to the left than square in the middle. I figured it was a flaw in my chain but I've tried several albums, several sources and all my headphones but it seems like the culprit is my right ear. I'm starting to get worried since I value my hearing above anything.
Is there any way to prove this? Has anyone here experienced the same? I haven't noticed a difference between left and right untill recently.
