Decibullz Product Warning

WARNING! Improper fitting or misuse of earplugs will reduce their effectiveness and could result in hearing loss or injury.

Test earplugs in progressively louder environments. If at any time you feel like you don't have a sound isolating seal or don't feel properly protected remove yourself from that environment immediately. Do not enter a loud environment right away. Start in a quiet, low noise environment and slowly increase your noise exposure to make sure your Decibullz are providing adequate protection.

To prevent hearing loss always wear hearing protection when exposed to noise levels 85 dBA or higher. NOTE: The NRR system may overestimate the hearing protection provided during typical use. Decibullz recommends reducing the NRR by 50% for estimating the amount of noise reduction provided

Wear hearing protection at all times that you are exposed to loud noise

The molding process involves heating your molds and forming them to your ears. DO NOT PLACE THE HOT MOLD IN TO YOUR EAR. Wait until the mold is warm and pliable.

Remove all objects and piercings from the concha or bowl of the ear before molding the earplugs. Piercings can become trapped in the molding material. 

CHOKING HAZARD: Keep small parts away from children and pets. Parts are nontoxic but may interfere with breathing if caught in windpipe.



1. Check the fit of your custom Decibullz product before entering any loud environment. Be sure that once the custom earpieces are in place, that they seal the ear closed. Once you put both earpieces in, check the fit by talking loudly. You should be able to hear your voice clearly, but at a reduced volume, and the noises around you should not sound as loud as they did before you put the earpieces in. Repeat test two additional times, wearing only one earpiece at a time to compare actual volume to filtered volume, and to be sure both ears are getting an equivalent seal.

2. If you aren’t sure you have inserted the earpiece correctly, or if you feel that you are not getting a complete seal of the ear canal, take it out of your ear and try some of the other tips provided in the packaging. If, after trying the different sizes and styles of tips, you still do not feel the earpieces are fitting correctly or providing a proper seal, then you may need to remold your custom plastic earpieces.

3. Re-check the fit often. Your earpieces may loosen up when you talk and chew. If this happens, you could lose protection from loud noise.
