I got tinnitus in 2010 in my right ear after a neck injury.
In the beginning I didn't associate it with hearing at all, my hearing tests came back normal or even better than average for my age then 23 or so.
It is quite a bad case, I can hear it everywhere if I want to. It is not tonal, sort of a sizzling sound at what feels like 17khz or there about. I still hear that but my hearing in the right ear these days drops dramatically at around 12-13khz.
HOWEVER, eventually I adapted quite well and learned to accept it. It got me involved with Headphones in the first place, because when using them you cant hear it. Same goes for running water and a shower, always a relief when it is a bad day.
I was still able to complete stuff like the goldenears challenge with it.
I do try to keep volume at or below 82db or so.
I found that over ear cans are best for it, in-ears seem to aggravate it for several days, or maybe thats just in my head.
Usually it returns to baseline level whatever happens.
But I still see friends and others walking around with their iphones and whatnot at 100% volume :S
