I was diagnosed with this and have lost some hearing in my right ear. Since I found out I have it, I have started using Docs Pro Plugs and love them. First, they keep me from worsening. Second, no water gets in my ear...none. I love being able to role all day long and not have water sloshing around in my head. I don't wear nose plugs anymore since getting the ear plugs. And finally, you can still hear with them in. Sound is diminished some, but its better than totally losing one's hearing. Here is a link:

You will need a sizing chart (you should be able to download one and print it out from the website).
