8. Important Usage Notes

Correct Wearing Method:

• Adjust the earphones to a comfortable position after wearing them.
• The included ear pieces come in three sizes (S/M/L) to ensure a good fit for optimal sound quality. Try different sizes to find the best fit.
• Turning the ear pieces inside out can help stabilize the stem for easier attachment.

Bluetooth® Radio Interference:

• Bluetooth® is a wireless technology operating in the 2.4GHz band. Communication range is approximately 10 meters in open areas without obstacles.
• Obstacles such as human bodies, metal, or walls can affect the communication range.
• Interference may occur in areas with other 2.4GHz wireless devices (e.g., Wi-Fi routers), near microwave ovens, or other sources of electromagnetic waves.
• Avoid using the earphones in environments with strong electromagnetic waves, such as near medical equipment, in airplanes (unless permitted by the airline), near priority seating on trains, or in locations with flammable gases (e.g., gas stations).
• Conversely, the radio waves emitted by this product may affect other electronic devices. Turn off or disable Bluetooth® in sensitive environments to prevent potential issues or accidents.
