Over-the-head hearing protection with Noise Reduction Rating (NRR) of 28 dB for moderate to high noise exposure
Twin headband design helps reduce heat buildup with good fit and balance
Wire headband offers comfortable pressure during prolonged usage
Earcups tilt to ensure a customized fit and comfort for individual users
Electrically insulated (dielectric) wire headband helps reduce exposure to electrical hazards

3M™ Peltor™ X-Series Over-The-Head Earmuffs X3 help protect hearing in high noise exposure environments with a Noise Reduction Rating (NRR) of 28 dB. A newly designed spacer improves attenuation without a double cup design, excess bulk, or excess weight. When correctly selected and worn, these lightweight hearing protection products help reduce exposure to hazardous levels of noise and loud sounds.

High level hearing protection without sacrificing comfort

Specifically designed to enhanced worker comfort, these earmuffs combine a lightweight design with soft contact points and adjustability. The twin headband design helps reduce heat buildup while offering a good fit and balance to make the headband more comfortable. The wire headband provides just enough pressure to ensure a secure fit, but never too much so as to become uncomfortably tight. Individual wearers can customize the fit of these hearing protectors with the adjustable earcups that tilt. Soft and wide cushions help the earmuffs seal comfortably around the ears, a feature that potentially can increase hearing protection compliance by workers in environments where hearing protection may be required. Easy-to-replace cushions and inserts help prolong the life of the earmuffs and keep them clean.

Versatile hearing protection for many work environments

Suggested applications and worksites for these earmuffs include metal processing, automotive, airports, construction, textile manufacturing, chemical and pharmaceutical manufacturing, cement manufacturing, printing, woodworking, heavy engineering, foundry, steelworks, mining, and quarrying.

Electrically insulated wire headbands

X-Series Over-the-Head Earmuffs feature electrically insulated (dielectric) wire headbands. The metal components of the headbands have been covered by a non-conductive material for use in a low voltage electrical hazard (less than 440 V ac). The product has been evaluated at an external laboratory against a modified test method based on EN397:1995. During assessment, the leakage current did not exceed 1.2mA when the external surface of the product made contact with an electrical source. The user must determine the overall suitability of the product for the intended application taking into account any hazards other than noise for which the product is tested.

Importance of hearing protection

Exposure to loud noises can adversely affect the ability to hear over time. Wearing proper hearing protection devices can help in reducing the harmful effects of noise. Sounds levels are expressed in decibels, often abbreviated as dB. Higher decibel numbers indicate louder sounds. Typical decibel levels associated with common sounds include: outdoors with no people or traffic 20 dB, normal conversation 60 dB, power lawn mower 90 dB, chain saw 110 dB, and 12-gauge shotgun 165 dB. The hearing protector NRR can be used to evaluate different hearing protection options. However, the actual level of protection varies depending on fit, wearing time and other factors.
