About Howard Leight
Howard Leight Industries has manufactured hearing protection in San Diego, California, producing the Impact Sport and Max-1 series that have become the standard for shooting sports and industrial hearing conservation programs across the United States.
Heritage & History
Howard Leight Industries was founded in San Diego, California and has grown to become one of the most recognized names in American hearing protection. Now a brand under Honeywell Safety Products, the San Diego operation continues to manufacture and develop earmuffs and earplugs that protect the hearing of industrial workers, construction professionals, military personnel, and recreational shooters.
The Impact Sport electronic earmuff became the defining product in its category — an earmuff that electronically amplifies ambient sound to a safe level while automatically compressing loud impulse noises like gunshots to 82dB. This technology allows hunters and competitive shooters to hear range commands and ambient sounds clearly while protecting against hearing damage from shots fired.
Made in San Diego, California
Howard Leight manufactures its earmuffs and earplugs at the San Diego facility, where the electronic components of the Impact Sport are assembled and tested. The Max-1 disposable foam earplugs — rated NRR 33, the highest noise reduction rating available — are produced using a proprietary foam formulation that expands slowly after insertion, providing a better seal than faster-expanding competitive products.
The NRR ratings on Howard Leight products are verified through standardized testing at the San Diego facility, with ongoing production quality control that ensures consistency between batches. Industrial customers purchasing earplugs in bulk for hearing conservation programs depend on that consistency — a batch of under-performing earplugs in a loud manufacturing environment has direct consequences for workers' hearing health.
