Hydro Seals from JBL utilize an advanced multi-baffle design that provides exceptional protection against water entering the ear canal, while still allowing clearing of the ears. This is all possible thanks to Hocks Noise Braker technology, an industry first. This system creates a force-field like barrier to prevent water from reaching the inner ear without completely sealing it. Thus sound waves can pass through while preventing pressure from water intrusion.
Hydro Seals greatly reduce the chance of infection by keeping bacteria from growing in stagnant inner ear water, help to prevent temporary loss of equilibrium, and reduce the chance of surfer’s ear by sealing out cold air and water, exposure to which is the primary cause of exostosis.
