More Info

NOTE: The X-Series (over-the-head) headband version is electrically insulated - sometimes referred to as ”dielectric”. The metal components of the headband have been covered by non-conductive material for use in a low voltage electrical hazard (less than 440 V ac). During assessment, the leakage current did not exceed 1.2mA when the external surface of the product made contact with an electrical source. 

The NRR may overestimate the hearing protection provided during typical use. 3M recommends reducing the NRR by 50% for estimating the amount of noise reduction provided.
