Microban antimicrobial protection helps prevent the growth of odor-causing bacteria on the earplugs. Protection from water and noise. Waterproof. For swimming, sleeping, snoring. BioEars were developed to help reduce the risk of earplug contamination. Noise Reduction Rating: 22 decibels (when used as directed). The range of noise reduction ratings for existing hearing protectors is approximately 0 to 30 (higher numbers denote greater effectiveness).
1. Make sure hands and ear opening are clean and dry. Shape the whole earplug into a ball. 2. Place earplug over ear opening and flatten to form airtight seal. Avoid hair. 3. DO NOT insert directly into ear canal! Use whole earplug - do not cut, break apart, or elongate. Discard when soiled or no longer sticky. BioEars are reusable. Roll and reshape BioEars each time before use.
Children should always be supervised by an adult. Keep away from infants or small children because, while non-toxic, swallowing earplug may interfere with breathing which could result in serious injury or death. Never use for swimming at depths of more than 10 feet (3 meters) of water.
