Foam Ear Plug Refill
Patented articulated shape for improved fit • The Noise Reduction Rating (NRR) is 28 dB • Helps reduce pressure inside the ear canal for improved comfort • Rolls down for easy insertion and fit for small space ear canals • New softer formulation for improved comfort • Hypo-allergenic material • WARNING - Research suggests that many users will receive less noise reduction than indicated by the NRR due to variation in fit and wearing time. 3M™ recommends reducing the NRR by 50% for estimating average noise reduction provided
