Decibullz Custom Molded Earplugs are easily and quickly fitted to the exact shape of your ear. Reusable and extremely comfortable, this creates a perfect fitting, low-profile earplug that will never hurt, never fall out and provide superior noise isolation.

Simply heat the Decibullz thermoplastic molds in boiling water, let them cool and shape them to your ears. It’s that easy. If you don’t get a perfect fit the first time, don’t worry. Decibullz are the only custom earplugs that are re-moldable. Decibullz Custom Molded Earplugs are perfect for shooting, traveling, swimming, loud concerts, and musicians. 

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

  • Absolutely worth the investment.


    I spend a good 8 hours a day in a noisy machine shop. Most of the time I have to readjust and reform the disposable ear plugs provided at the shop. Even worse the reusable pair I have always needed readjustment especially right after I would get grime all over my hands/gloves and that would transfer onto the ear plugs. I think I spent more time washing them then actually wearing them while working. Since my purchase of your custom molded earplugs I only rarely have had to readjust them. I put them in and forget about them for the 2 to 3 hours I work between breaks. These are a wonderful product.

  • Super product!


    Order two pairs, and have been using them for tunnel flying. They're great!

    Would suggest a couple of things:

    - include a couple of pairs of foam tips, not just one pair.

    - include a lanyard as standard.

    - add a note in the instructions to remind users to make sure that when they mold the polymer to their ear and around the black plug, that they ensure that there is polymer all the way around the black base, otherwise you risk leaks!
