Kill the noise, not the sound. Take care of your hearing and always protect it from the damaging noises that surround us. From gigs and sport fixtures to the sound of a lawnmower and a tube station, these Killnoise ear plugs are the perfect hearing defender to have with you. 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.
