8. Safety Information

Proper use of hearing protection is crucial for preventing noise-induced hearing loss. Please read and follow these safety guidelines:

• Always wear the hearing protection in noisy environments where sound levels exceed safe limits.
• Ensure a snug fit over your ears to achieve the stated Noise Reduction Rating (NRR) or Single Number Rating (SNR). Any gaps can significantly reduce effectiveness.
• Do not modify the earmuffs. Modifications may compromise their protective capabilities.
• Keep the earmuffs clean and free from debris that could affect the seal or internal components.
• While using the Bluetooth audio feature, be aware of your surroundings, especially in environments where situational awareness is critical for safety.
• Avoid listening to audio at excessively high volumes for prolonged periods, even with hearing protection, as this can still contribute to hearing fatigue or damage.
