A buddy of mine does custom ear molds (I've got a set of them with speakers wired into my racing helmet comm system). I just had him take the impressions for a set of passive (ie - no electronics) ear molds for shooting (they have a filter for the loud stuff). I'll let you know how they work once I get 'em! A few mutual friends have them and love them! He does offer electronic versions with MANY options too!
