Decibullz High Fidelity Earplugs
Model: FLTR-HFE
WARNING
Improper fitting or misuse will reduce effectiveness and may result in hearing loss or injury.
Always ensure earpieces are inserted correctly before use.
Do not insert molds while hot—allow them to become warm and pliable first.
Test your earplugs in progressively louder environments before full-time use.
Do not use if you have ear drainage or a perforated eardrum unless approved by a physician.
Filters are not hearing protection on their own; they must be used with molded earpieces and tips.
Check tip attachment before each use.
Remove slowly to avoid damage to the eardrum.
Keep parts away from children and pets (choking hazard).
Remove all ear piercings before molding.

Step 1: Prepare
Review video instructions: decibullz.com/high-fidelity-instructions
Attach a small silicone tip to each mold (do not use foam tips).
Ensure the tip is securely attached by gently pulling.
If unsure on size, start small—you can change tips after molding.
Step 2: Heat the Water
Microwave: Fill two ceramic/glass cups with 3–4 inches of water and boil.
Kettle: Boil water and pour into two cups (3–4 inches each).
Do not microwave the mold.
Do not use paper, plastic, or Styrofoam cups.
Step 3: Soften the Mold
Place one mold per cup to prevent sticking.
Let molds sit in the hot water for 5 minutes.
Step 4: Cool
Remove one mold using a metal spoon.
Let it cool for 30 seconds.
Step 5: Insert Filter
Insert the High Fidelity Filter (in housing) into the softened mold.
Step 6: Insert in Ear
Insert the assembled earpiece into your ear.
Align the tip with your ear canal and press firmly on the filter.
Step 7: Shape
Smooth the mold into the concha (bowl) of your ear using your fingertip.
Avoid using fingernails.
Step 8: Cure
Leave the mold in your ear for 5 minutes.
Press on the filter every 30 seconds to reinforce the seal.
Step 9: Remove
Remove the mold from your ear.
You may now switch to a different size silicone tip if desired.
Step 10: Repeat
Repeat the molding process for the other ear, starting at Step 4.
Testing and Fit Tips
Talk loudly: your voice should sound slightly reduced in volume.
Use a mirror to verify alignment.
Try different tip sizes and combinations to get the best fit and seal.
Re-mold if the fit feels off or if the seal is weak.
Molding Tips for a Better Fit
Start with a smaller tip to simplify molding.
Once molded, swap in your preferred tip size.
Each ear may require a different tip size.
If any part of the mold is too firm, remove the filter and reheat the mold in hot water.
For small ears, you can carefully trim the mold slightly and re-soften.
For large ears, shape more of a shell around the concha area.
Cleaning Instructions
Remove the filters before washing.
Clean molds and tips with mild soap and warm water.
Rinse thoroughly and dry completely before use.
Inspect for damage before each use.
Replace tips if torn or loose.
Safety Notes
Choking hazard: Keep small parts away from children and pets.
Heat exposure warning: Do not leave in hot cars or direct sunlight.
Temperatures above 120°F / 49°C may deform the molds.Do not use with ear infections or open eardrums unless cleared by a doctor.
Remolding Instructions
To re-mold for better fit or comfort:
Remove the filter from the mold.
Reheat the mold in hot water for 3–5 minutes.
Repeat the molding steps.
Testing Your Fit
Test in progressively louder environments.
Your voice should sound quieter and clearer.
If needed, try new tips or re-mold for better seal and isolation.
