Noise-canceling headphones with integrated hearing protection for construction helmets

1. Noise-canceling and sound-absorbing earmuffs for V-type helmets. 2. The helmet-mounting version attaches directly to many industrial safety helmets without additional accessories. 3. High-density foam ear cushion ensures optimal sealing and low noise levels for increased comfort. 4. This earmuff utilizes dual-shell technology that minimizes internal resonance for optimal high-frequency attenuation. 5. Airtight ring filled with high-density foam for optimal fit and reduced contact pressure. Features: Noise-canceling and sound-absorbing earmuffs for V-type helmets. The helmet-mounting version attaches directly to many industrial safety helmets without additional accessories. High-density foam ear cushion ensures optimal sealing and low noise levels for increased comfort. This earmuff utilizes dual-shell technology that minimizes internal resonance for optimal high-frequency attenuation. The acoustic bond between the inner and outer shells ensures maximum low-frequency attenuation. The airtight ring, filled with high-density foam, ensures an optimal fit and reduced contact pressure. Meets the requirements of industrial applications in many noisy environments. Specifications: Condition: 100% Brand New. Model: With Ear Protection for Helmet. Material: PVC. Color: Black.
