Reviewers say that Mack's AquaBlock earplugs do exactly what a swimming earplug should do: Keep water out of your ear canals. Their flanged, pre-molded silicone design is soft, comfortable and easy to clean. Because they insert in the ear canal, these earplugs should not be used by children under the age of 7, anyone with ear tubes or someone who has had recent ear surgery.
Provides a good seal. Mack's AquaBlock earplugs are made of pre-molded silicone, shaped into a series of flanges that help them form a good seal inside your ear canals and adjust to pressure changes easily. "These really work!! First earplugs that actually don't leak (follow insertion instructions by pulling up ear) and stay in the ears," writes one happy user at SwimOutlet.com.
Because they're only meant to keep water out, Mack's AquaBlock earplugs don't have an official noise reduction rating -- but reviewers at both Amazon.com and EarPlugStore.com say they help cut down on noise, too.
Soft and comfortable. Hundreds of user reviewers say that Mack's AquaBlock earplugs are soft, comfortable, and easy to insert and remove (thanks in part to a textured outer portion that's easy to grip, even with wet hands). One reviewer at EarPlugStore.com notes a little ear soreness after a long swim, but still proclaims Mack's AquaBlocks "the best ever."
If you have large ear canals, however, some users complain that these earplugs can fall out or go too deep into your ear.
Washable and reusable. Although Mack's AquaBlock earplugs cost about $2 per pair, they're washable and reusable -- so they cost a lot less over time than disposable earplugs would. One reviewer at SwimOutlet.com says he used his for 15 months before replacing them.
Reviewers on Amazon.com say these earplugs are easy to clean, but warn that you shouldn't buy the clear ones because they're hard to find if you drop them in the water (they're also available in purple). Both colors come with a small carry case, which users say makes it easier not to lose them in your gym bag.

They also like that AquaBlock earplugs are easy to put in and take out, and easy to clean -- but we do find a few complaints.
