3M Peltor X-Series Ear Muffs – X4A

The 3M™ Peltor™ X-Series X4A Ear Muffs is a new technology built for comfort, design, and protection. The X4A utilizes a newly designed spacer, foam liners, and ear cushions to improve attenuation. The lower-profile earmuffs are lightweight and can easily be used with other personal protection items. The earmuffs feature an electrically insulated headband, often referred to as “dielectric”. The earcup pivot points tilt for optimum comfort and efficiency. NRR 27dB, CSA Class AL. *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.

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). As there are no applicable standards for testing ear muffs against electrical insulating properties, 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 user must determine the overall suitability of this product for the intended application taking into account any hazards other than noise for which this product is tested.
