I got Tinnitus a few years ago in my late 20s, from ear in headphones, I always kept the volume at 50% but still got it. As far as I know, there is no true cure for tinnitus. I have read ginkgo biloba helps, which I have been taking for about a year but has done nothing. I will try the B-6. Good thread, thanks for resurrecting it, as I'd bet many pilots suffer from this.
