Thunder Series - For Electrical Environments

When it comes to selecting an earmuff, comfort reigns supreme with workers. That's why the Thunder series earmuff is 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.

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.
