When I am listening to headphones, on most of the songs it sounds like the vocals is not at the dead center. It's almost as if the singer is at the right side a little bit. At first I thought it was my hearing, so I reversed the headphones - then it sounded like the vocals are a bit towards the left, so it's not me. The thing is, it's not my headphones/source either. I can use a headset at work plugged straight into the computer and it's the same thing. Anyone else experience this before?
