JUNIOR SOFT FOAM EARPLUGS
1. How does the size differ between the Mack's® Original SafeSound® Soft Foam Earplugs and the newer Mack's® SafeSound® Jr. Soft Foam Earplugs?
The Jr. sized earplugs are just as long as the original size, but they are slightly smaller in diameter.
2. 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 the junior size 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® SafeSound® Jr. will lessen this pressure and thus increase the comfort level.
3. 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 and is hypo-allergenic.
4. Can the earplugs be cleaned?
No. If these earplugs become soiled, they should be disposed of.
5. 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.
6. 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.
