Warnings & Precautions

Remove soft foam earplug slowly with twisting motion to gradually break the seal. Rapid removal may damage eardrum. 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 polyurethane 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?

Please re-read the directions on the package and check out our instructional video on our product detail page to ensure you are getting the best fit and performance. The earplugs should be inserted so that there is just enough of the earplugs sticking out of your ear canals that you can easily grasp them with your thumb and forefinger for removal. 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 absorbed some sweat from the ear canal, try another, unexposed plug. A totally dry plug will retain its compressed shape and rigidity slightly longer, making it easier to insert. A sign that the earplug is sealing your ears properly is that your voice will sound more internal and exaggerated. Following these directions and tips with help ensure a proper seal and noise reducing benefits as well as help keep the earplugs securely in your ears.


I am a 7th grader and have been using the Mack’s Slim Fit Soft Foam Ear Plugs in my daily school band practice for a month.  While most ear plugs are usually a little too big for my ears, the Mack’s Slim Fit Soft Foam Ear Plugs slip comfortably into my ears and fit perfectly. The ear plugs effectively reduce the intensity of the music, and most importantly they preserve the sound quality. Also, I can still hear the commands of my band director without any problem.  Mack’s Slim Fit Soft Foam Ear Plugs offer great protection for my hearing. I can now play music loud enough for all the audience to hear while protecting my ears.

After trying various types and sizes of earplugs, these Slim Fit soft foam ear plugs are the only ones I found that I could wear all night without any pain from the plugs being too large, AND without the plugs popping out halfway through the night.  But they are still easy to remove in the morning.  Finally I can sleep comfortably all night without being woken up by my noisy upstairs neighbors.  Definitely consider giving these a try if you have the problems I did – with plugs falling out or being too tight!
