3M&#8482 Peltor&#8482 X-Series Over-The-Head Earmuffs X4 are a low profile design that helps protect hearing in high noise exposure environments with a Noise Reduction Rating (NRR) of 27 dB. The ultra-slim low profile cup design improves compatibility with other personal protection equipment (PPE). 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.

Lightweight, Durable Hearing Protection
The OPTIME 105 features added mass and volume, plus a unique “double-shell” earcup design (two cups connected via foam inner layer) to reduce structural resonances to boost the noise reduction throughout the full range of low and high frequencies. The durable stainless steel headband resists bending and warping and distributes weight for a low-pressure fit. The lightweight headband works in conjunction with earcup pivot points that tilt to maximize wearer comfort. Soft, liquid &foam filled cushions help the earmuffs fit comfortably against the head to help provide an effective noise-blocking seal.

Important Noise Reduction Information
The Noise Reduction Rating (NRR) may overestimate the hearing protection provided during typical use. 3M recommends reducing the NRR by 50% for estimating the amount of noise reduction provided. The 3M™ Peltor™ Optime™ number (105) is a 3M guideline for the maximum time-weighted average A-weighted exposures in which the product, when properly worn and in good condition, can provide adequate protection to meet OSHA hearing conservation guidelines. However, the user must make sure that the specific earmuff and style selected provides appropriate protection. To be effective, the hearing protector should be used within a hearing conservation program that also includes noise level assessments by qualified personnel, training, audiometric testing and engineering controls. 3M™ Optime™ recommendations are based upon testing per Method B of the most recent ANSI standard, S12.6-1997 (R2002). Method B provides data that approximate the upper limits to attenuation that can be expected for groups of occupational users. Properly trained and motivated individuals can potentially obtain greater protection.
