Seals out water


  1. Reach over head and gently pull up and back on outer ear to straighten ear canal.
  2. Push and twist plug into ear to form an airtight seal. Be careful not to push plug in too far that you are unable to easily grasp it with thumb and forefinger.
  3. To remove, grasp earplug stem with thumb and forefinger and remove slowly with a twisting motion to gradually break the seal.


Rapid removal or failure to use as directed can cause serious injury or hearing loss.


If you are having trouble getting the plug to seal, re-insert and wiggle stem while gently pushing plug to form an airtight seal. If you are having trouble inserting the plug, try pointing the tip of the plug slightly forward, toward face, during insertion.

Warnings & Precautions

Recommended for ages 7 and up. Mack’s® AquaBlock® Earplugs are not recommended for use with ear tubes or by patients recovering from ear surgery unless directed by a doctor. Use Mack’s® Pillow Soft® Silicone Earplugs with ear tubes and for post-surgery protection. Do not use for scuba diving or at depths over 10 feet. Use only as directed. 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.

Cleaning Instructions

Wash with mild soap and warm water. Dry thoroughly before reinserting into ear. Store in original case. Discard if earplugs come in contact with lubricants, solvents or other chemicals. Earplugs should be inspected regularly for serviceability. Replace hard, torn or deformed earplugs. If used daily, replace every 2 to 4 weeks.


Mack’s® AquaBlock® Earplugs are safe for use in salt and chlorinated water. Earplugs should be inspected regularly for serviceability. If they become hard, torn or deformed, they should be replaced.


What are the earplugs made of and do they contain latex?

The earplugs are made of pre-molded, non-irritating silicone rubber and do not contain any latex.

Can the earplugs be cleaned?

Yes. The earplugs can be cleaned with mild soap and warm water. Dry thoroughly before re-inserting into ear canal.

Are these earplugs designed to seal out water and reduce noise?

No. These earplugs were specifically designed to provide superior water protection. That is not to say that they cannot be used for noise protection, but the product does not currently carry a Noise Reduction Rating, nor does it make any claims that it is designed to be used for hearing protection.

Are there any application tips to help me get an airtight/watertight seal with the earplugs?

First try re-inserting after carefully re-reading the directions. If you still have trouble getting the earplug to seal, re-insert and wiggle the stem while gently pushing the earplug to form a waterproof seal. If you are still having trouble inserting the earplug into the ear canal, try inserting it with the tip pointed slightly forward toward your face. A sign that the earplug is sealing properly is that your own voice will sound more internal and exaggerated. Another way to check that you have a proper seal is to grip the stem of the plug and wiggle it (ever so slightly) in and out. A properly sealed plug will create a slight suction effect.

After a doctor inserts ear tubes, is it O.K. to use a flanged style earplug like this to keep out water, thus helping prevent infection?

We do not recommend this type of plug while wearing ear tubes. Since flanged earplugs are inserted into the ear canal, we recommend that they only be used by those without pre-existing ear health conditions. Use Mack’s® Pillow Soft® moldable silicone earplugs while wearing tubes as they seal the ear without penetrating the ear canal. Consult an E.N.T. (ear, nose, and throat doctor) to see if they are safe to use for your particular case. If the earplugs are corded, be sure to remove the cord before water activities.

Can these earplugs be used on children?

We recommend you consult an E.N.T. (ear, nose, and throat doctor) so that they can help you determine if the earplugs are safe for your particular application. While these earplugs were designed for older kids and adults, doctors and parents have used the flanged earplugs on kids as young as 7 years of age. We recommend using the Mack’s® Kids Size Pillow Soft moldable silicone earplugs for children 6 and under. In most cases, it will simply depend on the size of the individual’s ear canals. Usage should always be supervised by an adult and the plug should only be used if it can be fit comfortably and effectively to the ear canal. *See Warning Below.*

Warning: 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.


“As a sea kayaker who spends a lot of time practicing Eskimo rolls, your Mack’s AquaBlock Earplugs work perfectly for keeping the water out of my ears. They are the best I’ve found.”

Aaron Stander, Avid kayaker and novelist – Interlochen, MI

“I wear Mack’s AquaBlock ear plugs every time I surf. My left ear canal has grown 95% closed due to surfer’s ear. The use of your earplugs have prevented my condition from worsening. Most importantly, I don’t get swimmer’s ear infections when I wear them. I will eventually get surgery on my left ear to restore the size of my ear canal opening, but as long I keep wearing the ear plugs, I can delay this nasty procedure. I will continue to use Mack’s AquaBlock earplugs the rest of my life!”

Larry Reyes – Huntington Beach, CA

“I was the only one out of six of my friends using Mack’s AquaBlock Earplugs for the NYC Triathlon. I was also the only one who didn’t get an ear infection from swimming in the Hudson. Go Mack’s!”

Peter Shankman, CEO, Entrepreneur, Author, Speaker and Adventurist – New York, NY
