I just ordered a pair of filtered custom motorcycle earplugs the same as this one on the video from Robert in Northglenn. He's a service provider for this company called Big Ear who specializes in custom hearing protection that they said was started here in Boulder and now located in South Carolina. It will take 2 weeks before it gets here but I just believe in what they sell and how well their service is. I called them and they explained how the product works and what it's made of very well. They molded my ear impressions and it was really an experience. LOL! Will get back to you guys when my order arrives. Any one here who tried Big Ear before?
