3M PELTOR X4A Over-the-Head Earmuffs
The 3M PELTOR X4A combines a low-profile cup design with a U.S. Noise Reduction Rating of 27 dB. Its over-the-head design, wide foam cushions, and internally insulated stainless-steel headband support repeat use in demanding industrial environments where dependable hearing protection and compatibility with other PPE matter.
The X4A is designed to provide high attenuation in a relatively slim over-the-head profile. Its cup shape and cushion design help reduce bulk while maintaining a secure seal when the earmuffs are fitted correctly.

3M PELTOR X4A Earmuffs FAQ
What is the noise reduction rating of the 3M PELTOR X4A?
The X4A has a U.S. Noise Reduction Rating of 27 dB. Select hearing protection based on measured workplace exposure and the employer's hearing-conservation program.
Are the 3M PELTOR X4A earmuffs electrically insulated?
3M describes the X4A with dielectric earcups and an internally insulated stainless-steel wire headband. Follow the current 3M instructions and the site's electrical-safety requirements; do not treat hearing protection as primary electrical protective equipment.
Can safety glasses affect the earmuff seal?
Yes. Eyeglass temples, respirator straps, hair, or other objects between the cushion and the head can break the seal and reduce attenuation. Check the fit with all required PPE in place.
Which hygiene kit fits the X4A?
3M lists the HYX4 hygiene kit for replacing X4 Series cushions and foam liners.
Does the X4A require a size chart?
No. The X4A is an adjustable over-the-head earmuff rather than a size-selected garment. Adjust both cups until the cushions form an even seal around the ears.
