Troubleshooting

• No sound during Bluetooth music playback:
  • Ensure the volume on both your phone and the earphone is turned up.
• No ringtone for incoming calls:
  • Check if the phone's ringtone volume is adjusted correctly, especially in Bluetooth call mode.
• Low call volume:
  • Increase the earphone volume.
  • Ensure the earphone's sound unit is positioned close to your ear cartilage for optimal bone conduction.
• Water resistance for bathing/swimming:
  • The X15 supports IP56 life-level waterproofing, meaning it is resistant to sweat and light splashes. It is NOT suitable for bathing or swimming.
• Recommended charger:
  • Use a standard 5V 1A or 5V 2A phone charger. Do NOT use fast chargers, as this can cause the earphone to overheat and potentially damage the battery and mainboard.

User Tips

• Water Exposure: Avoid prolonged soaking in seawater or saltwater. After any exposure to water, rinse with clean water and dry thoroughly. Pay special attention to the charging contacts to prevent corrosion.
• Storage: If not using the earphone for an extended period, fully charge it at least once a month to maintain battery health.
• Post-Exercise Care: After exercise, wipe off any sweat from the earphone's surface, especially around the charging magnetic part, to prevent corrosion and maintain product lifespan.
