3M Earmuffs, Peltor X-Series, X4A, Over-the-Head, NRR 27 dB, Black

  • R 899.90


The X-Series range of Professional Earmuffs are 3M's latest advancement in hearing conservation.

New technologies in comfort, design and protection all come together in this groundbreaking earmuff line.

The X4A utilises a newly designed spacer, specially formulated foam liners and innovative ear cushions to help improve attenuation. This lightweight, lower-profile earmuff helps with compatibility with other personal protective equipment and is designed for protection against moderate-to-high level industrial noise and other loud sounds.

The X-series (over-the-head) headband version is electrically insulated - sometimes referred to as "dielectric". The metal components of the headband have been covered by non-conductive material for use in a low voltage electrical hazard (less than 440 V ac).

As there are no applicable standards for testing ear muffs against electrical insulating properties, 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 NRR may overestimate the hearing protection provided during typical use.

3M makes Hearing Protection Solutions innovatively easy. The 3M Peltor X series earmuffs are ideal for protection against noise arising from a wide range of applications in the workplace and leisure activity.

Examples of typical applications include:

  • Metal Processing
  • Automotive
  • Airports
  • Construction
  • Textile Manufacturing
  • Chemical and Pharmaceutical
  • Manufacturing
  • Cement Manufacturing
  • Printing
  • Woodworking
  • Heavy engineering
  • Foundry
  • Steelworks
  • Mining and Quarrying


  • Headband and headband cover/sleeve: stainless steel wire, TPE, polyester, polypropylene, acetal.
  • Hard hat attachment arm: stainless steel wire, acetal, polyamide.
  • Earcups: ABS/TPU.
  • Earcup inserts: PU foam.
  • Earcup cushions and cushion covers: PU foam and PVC.
  • Black/chartreuse colour. Dielectric.
  • Hearing protection style: over the head.
  • Noise reduction rating: 27 decibel. 
  • Size: one size fits most.

3M™ Peltor™ X-Series X-4 Over-The-Head Earmuffs 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.

These excellent earmuffs offer professional 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 customise 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.

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
  • 12-Gauge Shotgun 165 dB
  • The 3M NRR hearing protector can be used to evaluate different hearing protection options. However, the actual level of protection varies depending on fit, wearing time and other factors.
