Bilsom Howard Leight Thunder Ear Muffs
For Electrical Environments

When it comes to selecting an earmuff, comfort reigns supreme with workers. That's why the Howard Leight Bilsom Thunder Ear Muffs are designed with all-day comfort in mind. Headband earmuffs feature a unique dual-headband for better positioning and breathability, and non-deforming outer headband that minimizes pressure on the head. Plus, its dielectric construction withstands use and abuse, while protecting workers in electrical environments.

Howard Light Thunder Earmuff's new patented Air Flow Controlâ„¢ 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.


  • Insulated construction suitable for all workplaces, especially electrical environments
  • Uniform headband pressure for all head sizes, providing better comfort for long-term wear
  • Inner-ventilated headband minimizes pressure on the head, breathes easier in warm/humid climates.
  • Non-deforming outer headband withstands rough treatment in the toughest workplaces
  • Quick-Click height adjustment remains fixed during wear
  • Snap-in ear cushions make replacement quick and easy
  • Bilsom patented high performance technology
