My friend Greg Sandler was djing one night and felt dizzy after playing. Went back to his hotel, fell asleep, woke up the next morning with blood coming out of his ear and years later still suffers from hearing loss. though he regained some but i don't think hes more then 50% in that ear.

Yikes!

I want to get some of thoose noise reduction fitted ear pieces. Expensive but seem worth it.
