Mack’s Maximum Protection Soft Foam Earplugs | NRR 33

When snoring, traffic or everyday noise makes it hard to switch off, Mack’s Maximum Protection Soft Foam Earplugs help turn the volume down. Their soft Comfy Cush foam compresses for insertion, then expands to form a snug seal. Designed for slightly larger ear canals, they offer an NRR 33 laboratory noise reduction rating without an excessively bulky fit.

Best for

• Sleepers who want to reduce the disturbance of snoring and traffic.
• Studying or concentrating with fewer noise distractions.
• Travelling and resting in unfamiliar surroundings.
• People who prefer a fuller-fitting foam earplug.
• Noise reduction at loud events or around power tools, with protection chosen for the noise exposure.

Soft foam, a fuller fit and a reliable seal

Mack’s low-pressure polyurethane foam is designed to feel soft as it expands inside the ear canal. The tapered shape helps with fitting, while the orange colour makes each plug easy to spot before use. Made in the USA, Maximum Protection combines Comfy Cush comfort with an NRR 33 rating.

Imagine settling into bed, fitting your earplugs and giving the foam time to expand before your head meets the pillow. Getting that seal right matters more than choosing a rating alone.

What NRR 33 means

NRR is a laboratory-tested Noise Reduction Rating, not a promise that every sound will be reduced by 33 decibels in everyday use. The protection you receive depends on correct insertion, fit and the noise around you. Earplugs reduce noise; they do not create complete silence.

For hazardous workplace noise or shooting, follow the relevant hearing-protection guidance for your exposure. Do not assume an NRR rating alone establishes adequate protection or an Australian hearing-protection class.

How to fit them

1. With clean, dry hands, roll an earplug into a thin, crease-free cylinder.
2. Reach over your head and gently pull the ear upwards and backwards to straighten the canal.
3. Insert the compressed plug carefully and hold it while the foam expands. Follow the instructions supplied with your pack.
4. Check both ears for a secure, comfortable seal before entering a noisy area.

Remove slowly with a gentle twisting motion. Never force an earplug into place.

Will they suit my ears?

Maximum Protection is designed for slightly larger ear canals. If fuller foam plugs feel tight or uncomfortable, a smaller style such as Mack’s Slim Fit or Dreamgirl may be a better starting point. Stop using them if they cause pain or irritation.

For sleep, consider whether you need to hear alarms, children or other important sounds. These foam earplugs are for noise reduction, not keeping water out.

Care and replacement

Keep unused plugs clean and dry. Do not wash foam earplugs. Replace them when dirty, damaged or no longer soft enough to compress and expand properly, and follow the replacement guidance on the packaging. Do not share used earplugs.
