My ear plugs are the only dry plugs that are designed to be used underwater and are for all water activities.
Current dry earplugs for water activities (swimming etc.) create a .45lb psi pressure differential between the earplug and the ear drum for every 1' they are submerged below the surface, At 10' underwater there is nearly a 5lb psi pressure problem, seeking to rupture the tympanic membrane.
Utilizing a unique patented peel & stick method of attachment (they do not penetrate the outer ear canal when used as a medical device)and employing one of the many new, medical, waterproof, tacky, skin safe, silicone adhesives with the flexible silicone flange section on the earplug guarantees a water tight seal on most users. This skin safe adhesive method of attachment is presently unique (and patented).
