Noise Reduction Ratings (NRR) have been tested by an independent third party lab.
Noise Reduction Rating with foam tips: 31
Noise Reduction Rating with silicon tips: 24
THE NOISE REDUCTION IS DEPENDENT ON THE FIT OF THE EARPLUGS. TEST YOUR EARPLUGS BEFORE ENGAGING IN ANY ACTIVITY THAT COULD CAUSE HARM.
