Custom Molded Percussive Shooting Filters

The Percussive Filters protect users from the peak sound pressure of gunshots, and explosions, suppressing them to safe levels. When a percussive noise is not present the filters allow you to hear ambient noise.

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.

  • Works good.


    I boiled the water and poured it into a coffee cup and had no problem with melting the thermo fit ear pieces. It took me a couple of tries to mold them properly, but eventually got it. That was my problem, as I could not see what I was doing. This is not a flaw of the product. I have used the orange percussive inserts for shooting and they work perfectly acceptable. I have also used the non-percussive black inserts around heavy equipment and they work great as well. I experimented and found the large foam tips to work best. All-in-all I'm very happy with my purchase.

    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.
