Perfect for a variety of environments including gigs, festivals, sporting events and firework displays, these Killnoise ear plugs are truly multi-purpose. With a recent study showing a connection between hearing loss and chronic diseases, now is the time to do all we can to protect our hearing from damage. Instructions: 1. Straighten out the auditory meatus by pulling the outer ear upwards. 2. Grab the ear plug by the stem and with a light twist, push it into the ear canal. Care: After usage the ear plugs should only be washed with mild soap and water as chemicals can affect the product. If the recommendation is not followed, the protective function of the ear plugs can be decreased.
