Earmuff 3M Peltor SportTac 210100-478-GN — passive hearing protector, adjustable headband

The 3M Peltor SportTac 210100-478-GN earmuff is a passive hearing protector designed to reduce harmful noise levels in recreational shooting, motorsports and other loud environments. It combines a lightweight adjustable headband with cushioned ear cups to deliver a secure fit and comfort during extended use, helping to protect hearing while allowing clear situational awareness.

Advantages

The adjustable headband adapts to different head sizes for a stable fit, while the soft, foam-filled ear cushions provide long-wear comfort and an effective seal around the ears. Passive attenuation reduces impulse and continuous noise without batteries or electronics, offering reliable protection in varied conditions. The lightweight construction enhances portability and reduces fatigue during prolonged use.

Suitable for

• Recreational and sport shooting ranges
• Motorsports events and trackside work
• Yard work and use of loud power tools
• Industrial or workshop environments with high noise levels
• Situations requiring simple, battery-free hearing protection

Key specifications

• Type: Passive earmuff with headband

How to use

Position the earmuff cups over the ears and adjust the headband so the cushions form a continuous seal against the head. Ensure hair, glasses temples or clothing do not break the seal around the ear cushions for optimal attenuation. For best protection during shooting or loud activities, fit the cups prior to exposure to loud noise and maintain the seal during use. Store the earmuffs in a clean, dry place when not in use and inspect cushions regularly for wear.

Recommendations

Use the 3M Peltor SportTac earmuff as part of a hearing protection strategy: combine with earplugs when very high noise levels or prolonged exposure are expected, and replace ear cushions when visibly worn or when the seal is compromised to maintain effective noise reduction.
