Safety Instruction

1. Using earphones at high to moderate volumes for extended periods can result in permanent hearing damage. Keep volume levels moderate to low for safety.
2. Do not use while driving, cycling, operating machinery, or performing other activities that require awareness of surrounding sounds.
3. Avoid using earphones in thunderstorm weather, as they may not function correctly and could increase the risk of being struck by lightning.
4. Earphones may not work properly under high temperature or high humidity conditions. Do not use corrosive cleaners or oil to clean the earphones.
5. If the earphone comes into contact with liquids, wipe them away quickly.
6. If submerged in water, do not turn the earphone on until completely dried. (Liquid submersion voids the warranty.)
7. Keep the earphones and packaging out of reach of children.
8. Please use the original charging cable provided by the manufacturer and an appropriate adapter for charging.
