Optime II has been developed for demanding noise-hazard environments and muffles even extremely low frequencies to a maximum degree.
The sealing rings are filled with a unique combination of liquid and foam. The result is an optimum seal with low contact pressure, which provides snug comfort even during long-time use.
The sealing rings have ventilation channels and are covered with soft, patterned, hygienic foil.
Optime II is a suitable choice for environments with substantial industrial noise or construction machinery, airports and agricultural work.

The wire headband offers consistent pressure over prolonged wearing periods.
Earcup pivot points tilt for optimum comfort and efficiency.
Noise Reduction Rating (NRR)b 22 dB. CSA Class A. NOTE: 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 user must determine the overall suitability of this product for the intended application taking into account any hazards other than noise for which this product is tested. The 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.
