Use your hands to press the ear pods well into the ear canal using an inward motion. Protection levels are improved by pulling your ear up and back when fitting as shown. In a noisy environment lightly press the band inward with your fingertips as shown. You should not notice a significant difference in noise level. Proper Fit - If either or both earplugs do not seem to be fitted properly remove the earplug and reinsert. Removal - Gently twist earplug while slowly pulling in an outward motion for removal. Acoustical Check - In a noisy environment with earplugs inserted cup your hands over your ears and release. Earplugs should block enough noise so that covering your ears with your hands should not result in a significant noise difference.
