How to use: Simply place the earmuffs over your ears, adjust the headband to fit comfortably. Make sure the ear cups fully cover your ears. Note: Do not use these earmuffs in extremely wet or dirty environments. Also, if you feel any pain or discomfort while wearing them, stop using them immediately. Maintenance: Wipe the earmuffs with a clean, dry cloth regularly. Check the headband and ear cups for any signs of wear and tear. Replace the earmuff cushions if they start to lose their shape or effectiveness.
