Setup

1. Charging the Earphones

Before first use, fully charge the earphones. A voice prompt will indicate low battery during use.

1. Connect the magnetic charging cable to the magnetic charging port on the earphones.
2. Connect the other end of the charging cable to a 5V1A USB power adapter (not included) or a computer USB port.
3. The red indicator light will be solid during charging.
4. Once fully charged (approximately 2 hours), the indicator light will turn solid blue.

Important: Ensure the magnetic charging cable is correctly aligned with the charging port. Incorrect alignment can prevent charging or cause a short circuit. Use only a 5V1A charger to avoid overheating and potential damage to the battery or mainboard.

• Power Off: Press and hold the power button for 3 seconds. The red indicator light will turn off.

3. Bluetooth Pairing

The earphones automatically enter pairing mode when powered on for the first time or if not connected to a device.

2. On your mobile phone or computer, enable Bluetooth.
3. Search for Bluetooth devices and select "POLVCDG X13" from the list.

To transfer music files to the earphones' internal 32GB memory:

1. Connect the earphones to your computer using the magnetic charging cable.
2. The computer should recognize the earphones as a removable disk (often labeled "U disk").
3. Open the drive and drag-and-drop your MP3 or APE audio files into it.
4. Safely eject the device from your computer before disconnecting the cable.

Maintenance

• Water Exposure: Do not soak the earphones in seawater or salt water for extended periods. After use in water (especially chlorinated or salt water), rinse them with fresh water and thoroughly dry the charging magnetic port to prevent corrosion.
• Storage: If the earphones will not be used for a long time, charge them at least once a month to maintain battery health.
• Cleaning: After each exercise session, wipe any water or sweat from the surface of the earphones, paying special attention to the charging magnetic port. This prevents sweat and salt water from corroding the port and affecting the product's lifespan.
• General Care: Keep the product away from fire, extreme heat, freezing temperatures, and chemicals. Avoid impact or excessive squeezing of the product.
• Charging: Always use a charger with an output of 5V1A. Using a charger with higher voltage may cause the earphones to overheat and could damage the battery or mainboard.

Troubleshooting

Cannot switch to MP3 mode:

Ensure there are songs stored on the internal 32GB memory card. If the memory is empty, MP3 mode cannot be activated.

No sound from the earphones:

• Check if the volume is turned up on both the earphones and the connected device (phone/computer).
• For some mobile phones, you may need to enable "Synchronize volume with Bluetooth device" in your Bluetooth settings.

Earphones cannot charge or transfer data:

• Inspect the magnetic charging pins on both the cable and the earphones for any foreign objects or debris.
• Clean the charging pins thoroughly and try again.
• Ensure the magnetic cable is correctly aligned and securely connected.

Bluetooth connection occasionally drops:

• Ensure the earphones are within the 10m transmission range of your device.
• Minimize obstacles (walls, large objects) between the earphones and your device.
• Avoid strong electromagnetic interference from other electronic devices.
• Try re-pairing the earphones with your device.

User Tips

• Comfort: While designed for a secure fit, adjust the earphones to find the most comfortable position on your ears.
• Sports Use: These earphones are particularly well-suited for running and other outdoor activities, especially in warmer weather, as they do not interfere with headwear like caps.
• Swimming: The IPX8 rating makes them excellent for swimming. Remember to use MP3 mode for underwater listening as Bluetooth signals do not transmit well through water.
