Go to a hearing specialist and have them make you a custom set of molded ear plugs, they're not that expensive. You could have a set made so you can still hear horns and emergency sirens or on the other end of the spectrum you can get a custom set that literally makes you equivalent to a deaf person, then it wouldn't matter if you ride with out even a helmet or a screen at 100 mph. If you want to try it cheap, get yourself a kit and make them yourself: http://www.esafetysupplies.com/Radians-Custom-Molded-Earplugs.html?gclid=CN2isISih9MCFdcegQod-WcDDQ If you already tried custom molded ear plugs made for you from an actual ear Dr and you're still having the problems you describe, you're doing something wrong. If you're one of those people that has more hair growing out of their ears then on their head, custom molded ear plugs may not work for you unless you get that cleaned up. Good luck!
