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 Mack’s® 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.
