Abstract: An earplug includes a body made of a silicone material containing a phosphorescent material that causes the earplug to glow in the dark after exposure to light. A filter for reducing sound is positioned within the body. The silicone material includes 80-90% polydimethylsiloxane and 5-15% of the phosphorescent material, such as zinc sulfide, strontium aluminate, or rare-earth metal chelates. A fin extends from the body and fits into folds of an outer ear to secure the earplug in place. The body has a layered design with multiple sections that gradually decrease in diameter toward a tip of the earplug.

Abstract: An in-ear device is disclosed that comprises an earbud and a decorative article. A head portion of the earbud has an ear canal insert portion, first end of which is coupled with an ear plug. A faceplate of the earbud having first planar region which is traversely extended from second end of the ear canal insert portion to an area that is proximate to outer boundary of the first planar region. A second planar region of the faceplate corresponds to mounting region having recess portion adapted to house first metal coupling plate. The decorative article is detachable from the mounting region and has second metal coupling plate. At least one of first metal coupling plate and second metal coupling plate is magnetic material. The first metal coupling plate is complementarily sized and shaped to magnetically couple with second metal coupling plate when placed in proximity to first metal coupling plate.
