The 3M PELTOR X4A Earmuffs are over-the-head hearing protection earmuffs designed for workers who need NRR 27 dB noise reduction in manufacturing, construction, metal fabrication, facility maintenance, transportation, mining, oil and gas, and industrial work environments.
Built as part of the 3M PELTOR X-Series, the X4A combines a slim, low-profile earcup design with high attenuation for mid- to high-level workplace noise. The lightweight over-the-head wire headband helps provide steady pressure and a secure fit during extended wear, while the black and chartreuse earcups make hearing protection easier to identify during workplace safety checks.
The X4A uses slow-recovery, high-density foam and replaceable ear cushions to support comfort, hygiene, and long-term use. Replacement cushions and foam liners are available through the 3M PELTOR HYX4 hygiene kit.

Safety Note
