A comfortable, custom made earmold provides better hearing protection. 

The custom mold is made from your ear impression, to fit your ear only, providing the best seal to prevent harmful sound levels from entering your ear.

The earmold is a duplicate of the ear impression.

Your Custom Hearing Protection may be made either with the world famous Hocks Noise Filter® or as solid hearing protection. 

Custom hearing protection is available in solid colors, swirled colors, translucent colors, translucent clear, with or without cords. See color chart below.

Prevent leakage with a seal only available in custom units.  No swim mold can provide a 100% water-tight seal. However, a properly fitted mold will prevent most moisture from entering the ear.  They are recommended by swimming instructors and doctors for persons requiring protection of the outer ear.  Swim Plugs are made of silicone, a flexible, non-shrinking, durable material, offering maximum seal, comfort, and protection.

The sleeping plug is a solid plug, but with the outer surface of the mold phantomed (scooped out) for comfort when lying on the ear.
