Directions for use
With clean hands, hold earplug between thumb and forefinger. Roll and progressively compress the entire tapered end of the earplug to a small wrinkle-free cylinder.
To ensure fitting, reach hand over head and gently pull ear upward and outward.
Insert compressed, tapered end of earplug well inside ear canal. Hold 30 - 60 seconds until earplug expands. Release, then push in again for 5 seconds to ensure fit.
Remove earplug slowly. Use a gentle twisting motion to gradually break the seal. Rapid removal may damage eardrum.
Discard after several uses or as soon as dirt or wax accumulates on earplugs.
User fit check
In a noisy environment with earplugs inserted, cup hands over both ears and release. If the earplugs are inserted correctly, you should not notice a significant difference in attenuation. If a proper fit has not been obtained, move to a quiet area and repeat fitting instructions.
Remove earplug slowly with twisting motion to gradually break the seal. Rapid removal may damage eardrum.
Improper fitting will reduce effectiveness and could result in hearing loss or injury.
Keep away from infants and small children. These earplugs are non-toxic, but may interfere with breathing if caught in windpipe, which could lead to serious injury or death.
How does the size differ between Mack's Slim Fit Soft Foam Earplugs and more standard-sized foam earplugs?Mack's Slim Fit Soft Foam Earplugs are similar in length to most foam earplugs, but they are slightly smaller in diameter.My ears canals seem normal size to me, but earplugs are often uncomfortable in my ears if I wear them for an extended period of time. Will Mack's Slim Fit Soft Foam Earplugs be more comfortable for my ears?Ear sensitivity varies greatly from one person to another, and even from one ear to another, on the same person. Any pre-molded earplug that works by exerting a bit of pressure back on the ear canal to seal it properly may, over an extended period of time, begin to cause some discomfort to the wearer. People with smaller ear canals experience this discomfort more often as 'normal' sized earplugs don't fit as well into their canals. If you have smaller ear canals and / or sensitive ear canals, a smaller diameter earplug like Mack's Slim Fit Soft Foam Earplugs lessen this pressure and thus increase the comfort level.What are the foam earplugs made of and do they contain latex?The earplugs are made of urethane foam. The 'latex' in our foam earplugs is not natural latex, it is a synthetic latex technically called an emulsion polymer. It has the same properties as latex (water based, adhesive, etc.) but does not have the enzyme problem associated with natural latex.If, in the extremely rare instance you should experience any type of rash or skin irritation while using this product, please discontinue use immediately. Consult your doctor or go to your local medical emergency room if you believe you require immediate medical attention.Can the earplugs be cleaned?No. If these earplugs become soiled, they should be disposed of.Besides reducing noise, can these earplugs be used to seal out water?No. These earplugs were specifically designed to provide superior protection against noise. For water protection, we recommend that you try one of our moldable silicone or pre-molded flanged earplug products.Are there any application tips to help me get a proper seal with the earplugs?First try re-inserting the earplugs after carefully re-reading the directions. Be sure to insert the plug while pulling (with the opposite hand) up and back on the outer ear to straighten the ear canal. If you are still unsuccessful with a plug that has now warmed to body temperature, try another 'cooler' plug. A plug that is cooler in temperature will retain its compressed shape and rigidity slightly longer, sometimes making it easier to insert. A sign that the earplug is sealing properly is that your own voice will sound more internal and exaggerated.
