Peltor X4P3E hearing protector for helmet mounting is a hearing protector that attenuates sound up to 33 dB and has a smooth and aesthetically pleasing design. The earmuffs are lightweight and have a low profile that makes them easy to use with other protective equipment. Fluorescent yellow-green color ensures good visibility when working outdoors and thereby improves safety. New specially designed damping cushions and innovative material in the foam in the sealing rings, despite their neat format, provide excellent protection against noise from low to high frequencies.
