Mine tunes in background noise a lot, so pubs with noisy acoustics tend to be really uncomfortable. I’m not sure if that’s due to something more than just my ears though.
I have mild tinnitus, but i tend not to notice it. I thought I’d messed my left ear up for good after seeing Mogwai at the Anson Rooms in November '01, having stood right next to the speakers. It rang for a month before one say i noticed it was no longer ringing.
