Decibullz Custom Molded Earplugs are do-it-yourself custom earplugs that can be molded and ready to use in about five minutes. The ear plug fits to the exact shape of your ear, making it comfortable while providing superior noise isolation. These ear plugs reduce noise up to 31 dB. To use, simply heat the packaged thermoplastic molds in hot water, cool for 30 seconds, and shape them in your ears. The earplugs are re-moldable, providing the opportunity to repeat the custom process as needed to achieve ideal fit. Available in three colors (black, blue and orange).
