I've recently became addicted to head-fi, which consequently made me become addicted to headphones. Lately I have been listening to my music and movies at volumes that were really too high, I thought if I turned up the volume I could hear more detail in the sounds, but obviously there was a side effect, loss of hearing.
I now get this feeling that my hearing is impaired. The way I describe it as if you just read a series of books very fast or a night of intense gaming, of course...
