1. Roll and compress the earplug between the fingers into a smooth, crease-free cylinder. 2. To ensure a proper fit reach hand over head and gently pull ear upward and outwards. 3. Insert compressed, rounded end of the earplug well into the ear canal. The pointed end should go in first. 4. Hold for a few seconds while plug expands. When correctly fitted the earplug should not stick out of ear. Incorrect insertion does not give full protection.
