MaxiPlug Corded Earplugs Class 5 are industrial-grade hearing protection devices engineered for high-noise environments including mining, demolition, and manufacturing. These earplugs use a slow-recovery polyurethane foam and a tapered ergonomic design to ensure a custom-moulded seal that prevents noise bypass and maintains pressure-free comfort during extended shifts.
Achieving an SLC80 26dB certification, they assist OHS Compliance Managers in meeting AS/NZS 1270:2002 standards to mitigate risks of industrial deafness. The integrated corded design prevents loss in high-movement trade zones and allows for seamless integration with hard hats or earmuffs without compromising the protective seal.
Frequently asked questions
How are MaxiPlug Corded Earplugs correctly inserted?
Roll the foam tightly between your fingers, then pull your ear upward and insert the plug. Hold for 60 seconds to allow full expansion and an optimal seal. Proper insertion is critical for documented performance.
What noise reduction do these earplugs provide?
These earplugs provide a Class 5 rating with an SLC80 of 26dB. This rating confirms suitability for high-noise industrial and construction environments as per AS/NZS 1270:2002.
Can these earplugs be used with other PPE?
Yes, the low-profile, corded design allows compatibility with hard hats, earmuffs, and other personal protective equipment. The cord prevents loss without interfering with other headwear.
What if the earplugs do not block noise effectively?
Re-check your insertion technique. Ensure the foam is rolled tightly, inserted fully into the ear canal, and allowed sufficient time to expand. Inadequate fit compromises the Class 5 protection.
Are MaxiPlug Corded Earplugs reusable?
No, these earplugs are designed for single-use only. Reusing them can lead to hygiene issues and reduced noise reduction effectiveness. Dispose of used earplugs in general waste.
Applications and benefits

|---|---|---|
| Construction sites with heavy machinery | Delivers Class 5 noise reduction, complying with AS/NZS 1270:2002 for critical hearing protection. | Builders, operators, labourers |
| Mining operations with continuous excavation | Ensures effective hearing protection, guarding against long-term hearing damage in high-decibel environments. | Miners, drilling crews |
| Manufacturing plants with high-decibel equipment | Provides all-day comfort with soft polyurethane foam, reducing user fatigue and encouraging consistent wear. | Factory workers, machine operators |
| Welding and fabrication workshops | Corded design prevents loss, ensuring earplugs remain accessible and reducing interruption for re-insertion. | Welders, fabricators |
| Transport hubs and industrial yards | Individually bagged pairs ensure hygiene and easy distribution on busy worksites. | Logistics staff, rail workers |
How to apply MaxiPlug Corded Earplugs HEC644:
- Ensure hands are clean before handling earplugs.
- Roll the earplug between your fingers to compress the foam fully.
- With your opposite hand, pull the top of your ear upward and outward to straighten the ear canal.
- Insert the plug deeply into the ear canal and hold for approximately 60 seconds for the foam to expand.
- Test the seal by cupping hands over ears—noticeable noise reduction indicates proper fit.
Product limitations
- Not for: Continuous immersion or environments with persistent moisture. The foam is not designed for underwater use.
- Intended for: Single-use only. Reusing earplugs compromises hygiene and can reduce noise reduction effectiveness.
- Protection: Will not provide adequate protection if improperly inserted. Ensure a complete seal within the ear canal.
Safety and handling
Personal protective equipment
Use gloves when inserting in dirty environments to avoid contaminating the earplug before use.
Ventilation
Not applicable; earplugs do not generate vapours or emissions.
First aid
- Eyes: If foam particles enter the eye, flush with clean water. Seek medical attention if irritation persists.
- Ingestion: If ingested, seek medical advice.
Storage and disposal
Store earplugs in their original packaging to avoid contamination. Keep them between 5°C and 35°C. Dispose of used earplugs in general waste. Do not share earplugs between users.
Substrate guide
Proper fit within the ear canal is essential for achieving the stated noise reduction. Incorrect insertion reduces protection.
Human ear canals
Surface prep: Ensure ear canals are clean and dry before insertion. Roll the foam earplug into a tight, creaseless cylinder.
Primer: Not required. Proper insertion technique provides the seal. Pull the top of the ear up and back to straighten the canal for easier and deeper insertion. Hold the plug in place while it expands to form a seal.
