Care should be taken while their application:
    In order to acquire the optimal protective effect and the earmuff pad should be fitting with head tightly and any substances influencing the wearing tightness such as hairs around ears( try to set back the hairs as much as possible), thick or eyeglasses frame not fitting with head tightly, pencils or caps put on ears will reduce the protective property because of wearing earmuff loosely.
    Bending and changing head band shape should not be allowed, which make the head band loosely and further cause sound leakage.
