• The innovative 553 ZERONOISE is equipped with patented temples especially designed to facilitate the combined use with hearing protection devices: the shorter terminals and the reduced sections cancel the interference with cushions avoiding that the ear muff loses part of its attenuation capacity.
• The flexible and shaped temples give the operators comfort, and allows them to wear the glasses without having to remove the ear muffs.
