The thing I like about the custom ones is you can easily hear things, and they block out all the damaging stuff.
I've had ringing in the ears pretty bad too Terry, it really sucks bad. Knock on wood haven't had it in a while.
Not to derail the busted head thread but,...
I had ringing in my ears bad for about two years and one day I had a chance conversation with a Venezuelan doctor that told me she could fix it by realigning my jaw, after three appointments and wearing a night guard for two months the ringing is almost completely gone, apparently there is a nerve connection related to the jaw that causes some ringing problems.
