These earmuffs are systems to protect against noise, especially industrial noise, in environments such as factories, workshops or airports. They stand out from other earmuffs because they are exceptional in attenuating all frequencies, including bass.
Comfort is also a plus for these hearing protection helmets: the earpads are wide and filled with soft plastic foam for an ideal fit and low contact pressure. They have an attractive design and their features are as follows:
