The 3M X-Series X3A Earmuffs represent 3M’s latest advancement in hearing conservation, combining innovative comfort, design, and protection. Featuring a newly designed spacer, the X3A improves noise attenuation without the need for larger or double cup designs. Lightweight and low-profile, these earmuffs are ideal for protection against high-level industrial noise and other loud environments. The X3A also features an electrically insulated (dielectric) wire headband for added safety in low-voltage electrical hazard areas.

Key Features:

• Lightweight, High-Protection Design;
  Provides reliable hearing protection against high-level industrial noise while remaining comfortable for extended use.

• Electrically Insulated Headband;
  Dielectric wire headband with metal components covered by non-conductive material for use in low voltage electrical hazard environments (less than 440 V AC).

• Consistent Pressure;
  The wire headband offers uniform pressure over prolonged wearing periods.

• Adjustable Earcup Pivot Points;
  Earcups tilt for optimum comfort and efficiency.

• Certified Noise Reduction;
  Noise Reduction Rating (NRR) of 28 dB, CSA Class AL, and EN 352:2020 compliant with a Single Number Rating (SNR) of 33.

Important Safety Notes:

• NRR may overestimate protection during typical use; 3M recommends reducing the NRR by 50% to estimate actual noise reduction.

• While the headband has been tested for electrical insulation, users must determine overall suitability for their specific applications and any hazards beyond noise.
