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.
Improper fitting or misuse of earplugs will reduce their effectiveness and could result in hearing loss or injury.
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.
Work very well and can still hear people talking even quietly!
