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.
Terrible waste of money. Barley OK for rimfire calibers, not acceptable for any other ammo. Followed the instructions and remolded the ear pieces twice with no difference in performance. Definitely would not recommend.
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.
