Product Description

Caret Down

Decibullz Custom Molded High-Fidelity Earplugs lower sound evenly across frequencies while keeping speech and music clear. The Thermo-Fit™ earpieces soften in hot water and mold to your ear shape in minutes, creating a secure, comfortable seal you can remold if needed.

Balanced filtering helps reduce sensory overload without muffling the world around you—useful for busy environments, commuting, concerts, open offices, or recovery days when your nervous system needs less input.

Each set includes acoustic filters, multiple tip sizes, and a carry case for easy daily use. Designed for long wear, they stay put during movement and help you stay present without fatigue from constant noise.

How it helps those with Long COVID

Caret Down

Individuals with long COVID often experience heightened sound sensitivity (hyperacusis) and difficulty processing noise in busy environments. Decibullz Custom Molded Earplugs reduce ambient noise without distorting sound quality, allowing users to engage in conversations and activities comfortably. By reducing auditory overload, these earplugs may help improve focus, reduce stress, and enhance overall comfort in noisy settings — common challenges for long COVID sufferers. Scientific Explanation on How the Product Works:
Noise sensitivity (hyperacusis) is a common symptom in long COVID, stemming from dysfunction in the auditory processing pathways and the autonomic nervous system. Research suggests that the overstimulation of the auditory nerve due to increased sensitivity to sound can trigger a heightened stress response, leading to increased fatigue, brain fog, headaches, and nervous system dysregulation.

Scientific Explanation

Caret Down

Decibullz earplugs work by reducing overall noise exposure while maintaining sound clarity. By attenuating sound evenly across all frequencies, they help prevent overstimulation of the auditory nerve, reducing the stress load on the brain. Lowering sensory input in this way allows the brain and nervous system to remain in a calmer state, potentially improving cognitive function, reducing headaches, and improving overall mood.

Additionally, balanced noise reduction can improve the brain’s ability to filter and process sounds, reducing mental fatigue and enhancing focus. Research has shown that limiting exposure to high-frequency noise can also help regulate the parasympathetic nervous system, promoting relaxation and better sleep — factors that are crucial for recovery in long COVID patients. By protecting against sensory overload, Decibullz earplugs may contribute to improved cognitive clarity, reduced fatigue, and enhanced emotional regulation in individuals with long COVID.

FAQs

Caret Down

1) How do I use it?
Heat the molds in hot water, snap them onto the filter + tip, then press into each ear and hold while they cool. Test the seal and remold if needed. Wear whenever you want lower, balanced volume.

2) Can I combine it with other products?
Yes—many users pair these earplugs with sleep masks, neck pillows, or vagus-nerve-support tools for calmer environments. If you use hearing aids or in-ear monitors, check fit and clearance first.

3) Any safety notes?
Do not insert deeply or use with ear pain, infection, active eczema, or a perforated eardrum. Keep molds clean and dry. Not for underwater use or impact-noise protection (e.g., shooting ranges).
