The X5A earmuffs offer the highest NRR (31 dB) for an earmuff on the market which makes them ideal for very high noise situations. The high attenuation is possible as a result of a combination of advanced technologies including: newly designed spacers, specially formulated ear cup liners and innovative foam contained in the cushions. It features an electrically insulated wire headband, often 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). The product has been evaluated at an external laboratory against a modified test method based on EN397:1995. 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.
