Howard Leight Airsoft Ear Plugs

Four-flange design uses internal fins to create an interlocking, noise-blocking barrier within the ear’s air pocket for dependable attenuation upon proper insertion. Firm stem and tapered shape facilitate easy insertion and removal, and allow the earplug to sit comfortably in the ear canal. Regular size fits most.
Tested to ANSI S3.19. CSA Class AL.
NRR is the Noise Reduction Rating in decibels (dB). It is the average noise reduction obtained by a group of people wearing a specific hearing protector in a laboratory test. Research suggests that many users will receive less noise reduction than indicated by the NRR due to variation in earplug fit and and wearing time. It is recommended that the NRR be reduced by 50% for estimating the average amount of noise reduction provided.
