Passive Ear Muff – Sperian

Comfortably designed earmuffs feature a padded foam headband and super-soft ear cushions to eliminate pressure on the head. Air Flow Control technology delivers optimal attenuation across all frequencies without increasing the ear-cup size or weight. A patented baseplate chamber and high-tech, nonwoven layer manage the flow of air inside the earmuff to control how sound reaches the ear. Telescopic height adjustment remains fixed during use. Earmuffs are designed with a Noise Reduction Rating (NRR) of 30 for a high level of protection.
