Features for every worker
  • The ultimate in safety and protection
  • Your workers need the right level of protection. Not enough and they're vulnerable to hearing damage. Too much and they become isolated from their environment. That's why we offer a range of attenuation levels, each suited to different users, different environments. Whatever the situation demands, turn to Bilsom for the most innovative earmuffs in the industry.


  • Patented high performance technology
  • Bilsom's new patented Air Flow Control™ technology delivers optimal attenuation across all frequencies, without increasing earcup size or weight. As sound travels through the air in the earcup, a patented baseplate chamber and high-tech non-woven layer inside the ear cushion manage the flow of air and controls how sound reaches the ear. The result is better, more consistent overall attenuation for almost all industrial noise environments. Air Flow Control is a standard feature on all Leightning and Thunder series earmuffs.


  • Quick-Click height
  • Quick-Click height adjustment allows easy fit adjustment that stays in place
