Howard Leight's patented Air Flow Control delivers optimal attenuation across all frequencies, without increasing earcup size or weight. A patented baseplate chamber and high-tech non-woven layer manage the flow of air inside the earmuff to control how sound reaches the ear. The result is better, more consistent overall attenuation for virtually all industrial noise environments. Air Flow Control is a standard feature on all Thunder series earmuffs.
Howard Leight Cap-Mounted Earmuffs now work with North®Hard Hats and Face shields. These earmuffs have been engineered to seamlessly integrate with hard hats and face shields to provide an effective unit for worker head and hearing protection.
