JBL Hydro Seals Aqua Plugs
Hydro Seals utilize an advanced multi-baffle polymer design providing exceptional protection against water entering the ear canal. In addition to greatly reducing the chance of infection by inhibiting bacteria from growing in stagnant inner-ear water, Hydro-Seals also help prevent the temporary loss of equilibrium. Simple and effective to use, Hydro- Seals reduce the chance of surfer’s ear by sealing out cold air and water, which causes exostosis. Exclusive Hocks Noise Braker allows normal sound waves to pass through while preventing pressure build-up from water intrusion, making them ideal for divers that have trouble clearing their ears at descending depths.
Hydro Seals come available in three easy to stock sizes: Small, Medium, and Large. Fitting is determined by the size of the user’s concha bowl. Note that medium fits most people. Small is recommended for all sizes smaller than ¾ in, medium for anything between ¾ - 1 ¼, and large for those over 1 ¼ inches. To install, gently insert the stem into the ear canal until you feel the Hydro Seal lock into place. A slight twist may aid in insertion. The red plug is for the right ear, and the clear one is for the left. Make sure the Hydro Seals are seated correctly in the ear with the outer piece locked in the concha. If it's too large/small shift to the appropriate plug until the correct size is found.
