Decibullz Professional Music Filters with Lanyard


Model: FLTR-PRO




WARNING

Improper fitting or misuse will reduce effectiveness and may result in hearing loss or injury.

  • Do not insert earplugs while molds are hot. Allow to cool to a warm, pliable state.

  • Always wear hearing protection in loud environments.

  • Test your fit in progressively louder environments.

  • Filters alone are not hearing protection—they must be used with molded earpieces and tips.

  • Do not use with ear drainage or a perforated eardrum unless approved by a physician.

  • Remove earplugs slowly to avoid damage to the eardrum.

  • Inspect tips before each use to ensure secure attachment.

  • Keep away from children and pets (choking hazard).

  • Do not use where the lanyard may pose a strangulation hazard.




What’s Included

  • Left and Right EZ Shape Custom Molds

  • Professional Filters (in housing)

  • Max Isolation Foam Tips (S/M/L)

  • Open Single Flange Silicone Tips (S/M/L)

  • Filter Lanyard

  • Premium Zipper Carrying Case




Materials Needed (Not Included)

  • Glass or Ceramic Cups

  • Kettle or Microwave (for heating water)

  • Boiling Water

  • Timer

  • Metal Spoon

  • Mirror (recommended)




Molding Instructions

Step 1: Heat the Water

  • Microwave: Fill two glass/ceramic cups with 3–4 inches of water and boil.

  • Kettle: Boil water and fill cups with 3–4 inches.

  • Do not place molds in the microwave.

  • Do not use plastic, paper, or Styrofoam cups.




Step 2: Soften the Molds

  • Place one mold per cup. Molds will stick together if placed in the same cup.

  • Let sit in boiling water for 5 minutes.




Step 3: Cool and Prepare

  • Remove one mold with a metal spoon.

  • Let it cool for 30 seconds.

  • Insert the Professional Filter into the mold.

  • Attach a small silicone tip (not foam) for the molding process.

  • Check for secure attachment by gently pulling on the tip.




Step 4: Insert into Ear

  • Insert the mold into your ear, aligning the tip with your ear canal.

  • Press firmly on the filter to seat it securely.

  • The fit should feel snug and directed slightly forward (toward the eyes).




Step 5: Shape

  • Use your fingertip to press and smooth the mold into the concha (bowl) of your ear.

  • Avoid using fingernails to maintain a clean finish.




Step 6: Hold

  • Leave the mold in your ear for 5 full minutes to cure.

  • Press on the back plug every 30 seconds during curing.




Step 7: Remove and Finalize

  • Carefully remove the mold.

  • You may now swap the silicone tips for the foam tips to test comfort and seal.

  • Repeat steps for the other ear.




Fit Tips and Remolding

  • Each ear may require a different size tip.

  • Foam tips provide the highest NRR—try different sizes for best fit.

  • If the mold feels firm in the center, remove the filter and reheat for 1–2 minutes.

  • Molds can be remolded as many times as needed.

  • If any area feels uncomfortable, reheat the mold for 3 minutes and reshape.




Filter Lanyard Instructions

  1. Push down on the filter housing edge to remove the filter.

  2. Roll the filter out of the mold.

  3. Insert the filter (logo side up) into the smooth side of the lanyard.

  4. Once fully inserted, the lanyard is ready for use.




Testing the Filters

  • Speak out loud: your voice should sound clearer but quieter.

  • Surrounding noise should sound reduced but natural.

  • Re-test after adjusting tip size or remolding.




How the Filters Work

Decibullz Professional Filters offer flat attenuation, ideal for music lovers and concert-goers.
They maintain the original sound profile at a reduced, safer volume, allowing speech and ambient sounds to remain audible.
The filters are vented to reduce occlusion and improve comfort.




Safety and Maintenance

Heat Exposure Warning

Do not leave earplugs in hot environments (e.g., cars, direct sun). Temperatures over 120°F / 49°C may deform the product.

Cleaning

  • Remove filters before cleaning.

  • Wash all parts (except foam tips) with mild soap and warm water.

  • Rinse thoroughly and dry completely.

Inspection

  • Check tips and molds for wear before each use.

  • Ensure tip is attached securely before inserting.
