Earmuff 3M Peltor SportTac 210100-478-SV — passive hearing protector, 26 dB noise reduction

3M Peltor SportTac 210100-478-SV earmuffs are passive hearing protectors engineered to reduce hazardous noise levels by approximately 26 dB. The design combines deep, over-ear cups with a padded headband to provide stable, comfortable attenuation during shooting sports and other high-noise activities. Materials and construction prioritize fit and durability while remaining compact enough for transport to ranges and outdoor venues.

Advantages

The earmuffs deliver consistent passive attenuation of impulse and continuous noise without batteries or electronic components, making them low-maintenance and reliable in the field. Soft, contoured ear cushions improve seal and comfort for extended wear, while an adjustable headband allows users to customize fit across head sizes. The construction uses impact-resistant materials to withstand regular use in shooting and recreational environments.

Suitable for

• Sport shooting at indoor and outdoor ranges
• Hunting and clay target practice
• Workshops and industrial settings with high noise levels
• Lawn and garden equipment operation
• Any activity requiring reliable passive hearing protection

Key specifications

How to use

Place the 3M Peltor SportTac earmuffs over clean ears and adjust the headband until the ear cups sit comfortably and form a continuous seal around the ear. Ensure hair, glasses temples or clothing do not break the seal. For best attenuation, press the cups gently against the head to eliminate gaps. After use, wipe the ear cushions and outer surfaces with a damp cloth and mild detergent if necessary, and store the earmuffs in a dry place away from direct sunlight.

Recommendations

Use these earmuffs when exposed to high or impulsive noise levels, such as firearms discharge or heavy machinery. Verify fit before each session and replace worn cushions to maintain effective noise reduction. When combined with other hearing protection, follow safety guidelines for correct combined attenuation.
