How Often Should I Replace the Foam Ear Tips?Updated 16 days ago

Foam ear tips are a key part of what makes Decibullz Custom Molded Earplugs some of the best earplugs for hearing protection, especially when used in loud environments like shooting ranges, concerts, or industrial settings. However, like all foam earplugs, they are not designed to last forever.



You should replace your Max Isolation Foam Tips every 2–4 weeks, depending on usage. If you use your earplugs daily or in sweaty, dirty, or dusty environments, consider replacing them more frequently to maintain optimal hygiene and noise reduction.


Signs It’s Time to Replace:


  • Foam no longer expands fully after compression

  • Tips feel hard, sticky, or flaky

  • Fit feels looser than normal

  • Sound reduction seems less effective

  • Visible buildup of dirt, wax, or moisture

  • Tips are cracked, torn, or have missing pieces


Why It Matters:


Worn-out foam tips can:

  • Compromise your NRR 31 noise protection

  • Cause discomfort or a poor seal

  • Increase the risk of ear irritation or infection

Replacing your foam tips regularly ensures your earplugs maintain their top-rated hearing protection, especially for shooting, hunting, travel, and concerts.


Where to Get Replacements:


Replacement foam tips are available directly from Decibullz.com, including multi-size packs and upgrade kits. Choose the right size for your ears to maintain a comfortable and secure fit.
