High Attenuation in a Slim Cup
The 3M Peltor X4A Over-the-Head Earmuff carries a Noise Reduction Rating (NRR) of 27 dB in a slim, lightweight cup design for very high-noise environments. The X Series design uses a wire headband and soft, wide cushions to hold a consistent seal without the bulk of older high-attenuation muffs. PPE only performs to its rating when it is selected, fitted and used as the manufacturer directs. Keep the manufacturer's instructions with the product so wearers can check use and care limits at the point of issue.
