I have been using Pro Ear Dimension Magnum's. I have only been using them for about 7 years, but they are the best I have ever used. Not real good for long arms in prone.
Their new version of the Magnum is even quieter. My hearing went south in Vietnam, I am trying to hang on to everything I still have.
Unless your favorite comment is "what did you say?" Get good hearing protection.
Go figure.
