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.
They block out the gunshot but still allow me to hear my surroundings
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.
