Sometimes when I'm listening to my headphones. A song like "Vehicle". bye the Ides of March. it seems like some parts of the music are on only my left side. And then, later, the singers seems like they are only on my right side. The lights are out, but I'm scared. I think my headphones are broken or malfunctioning. Because some songs, like "North American Scum" by the Fall sound like they are in the center of my head (phones). Has anyone else experienced this?
