Good luck Sean!
I'm quite lucky to not have tinnitus yet. I do use the Hearos hi-fi plugs and really like those - especially around cymbals!
Fortunately, the Hearos don't really seem to affect the tonality of the bass frequencies, so that works well for me.
Like Dee, I do have some low-grade hearing loss that makes conversation in a loud room near impossible. All I hear is mush.
I've tried, without any success, to get the other band members to use hearing protection. I can't understand why anyone would risk their hearing in such a way.
I'll blame my hearing loss on Sean's old Carvin stack
My bass rig was never that loud!
