Decibullz DIY Thermo-fit Molded Earpieces combined with new cutting edge percussive impulse filter technology. Decibullz Percussive Filters protect users from the peak sound pressure of gun shots, artillery fire, and explosions, suppressing them to safe levels and protecting users from hearing damage. Custom molding is easy, simply warm the earpieces in water and shape to your ears. The earpieces can even be re-heated and re-shaped if needed. Unlike electronic hearing protection, Decibullz Filters never need batteries.
Great hearing protection. Love that I can hear in group hunting situations and had no affect from the 300 Win Mag that went off 10 feet from my right shoulder in last season's elk hunt. They are very comfortable and you don't get the "foggy" feeling general purpose earplugs give you. I would highly recommend and bought more for all my hunting partners.
I had to boil the first one I molded twice. Maybe I didn't get it hot enough on the first try. Decibulz works pretty good. I am glad that they don't itch (bacteria buildup). I just use alcohol or re-boil them to kill the germs.
