I hear sport ear is the way to go but you better get your insurance in on it if you want the customs cuz they are like 2 grand.http://sportear.com/
I went to get fitted for hearing aids on Tuesday. $6K for them. Of course after insurance (which we're losing with my wife's job today), $3.5K. The clinic is pushing hearing aids for one company, which I find extremely distasteful. I'm planning on having my earmuffs around my neck when I goose hunt this year. I need to protect what's left of my hearing. White noise? Part of my every waking moment.
Not waterproof for $6K.
