This version of Pyramex earmuffs uses an electronic suppression device that allows normal sounds, ambient noises, and voices through the earmuff, but blocks out harmful noises. This is a must for workers in high noise areas that still need to communicate with one another.
In the neutral position on the sound dial, the earmuff has a NRR rating of 20. Finally, the Pyramex PM4011 earmuff comes in an attractive black color, and adjust to fit most head sizes.
