Sensgard ZEM® SG-31 Natural Sound Banded Hearing Protector (NRR 31)

SensGard ZEM SG-31 was designed for high intensity noise environments. Recommended for any noise above 110 decibels, the SG-31 offers the patented Zwislocki protection from damaging noise while allowing speech and other useful sounds to be heard. Locking nylon headband positions the SG-31 firmly and comfortably on your head. SensGard ZEM banded ear plugs are fitted with SensGard Ear Chambers. These patented ear tips reduce loud noise to a safe level, but allow warning sounds and voices to be heard clearly across all frequencies with no distortion. No batteries are required; inside the chamber, sound waves are simply dampened, refracted and cancelled. Unlike most other ear plugs, the SensGard ZEM Ear Chambers are not inserted inside the ears, but instead, they rest over the openings of the ear canals, held in place by the ear band. At just 1.7 ounces, get 21st century hearing protection technology without bulk or batteries. The SG-31 is durable and folds to fit in your pocket or in the optional carry case. See More From Sensgard
