Directions ---------- While sleeping: use at home and on the go. At work or while studying: improve concentration in noisy environments. For music or loud noise: enjoy concerts safely and protect your ears when using heavy machinery. In the cold: protect your ears from low temperatures. Wash your hands. Remove the cotton packing and roll the earplugs between your hands to soften them. Mould the earplugs to fit the shape of your ear canal. Gently press the entire earplug into your ear. Pull your earlobe back with the opposite hand to open the ear canal; this will allow any air to escape and prevent any buzzing or ringing in the ear during use.
