Maintenance

To ensure the longevity and optimal performance of your Avantree AS50 headphones, follow these maintenance guidelines:

• Cleaning: Use a soft, dry cloth to wipe the headphones. Do not use abrasive cleaners or solvents. For earpads, a slightly damp cloth can be used, but ensure they are completely dry before use.
• Storage: Store the headphones in a cool, dry place away from direct sunlight and extreme temperatures. Avoid placing heavy objects on them.
• Battery Care: For optimal battery life, avoid fully discharging the battery frequently. Charge the headphones regularly, even if not in use for extended periods.
• Avoid Moisture: While the headphones are water-resistant, avoid prolonged exposure to water or high humidity. Do not submerge them.

Troubleshooting

If you encounter issues with your AS50 headphones, try the following solutions:

• Headphones not turning on: Ensure the headphones are fully charged. Connect them to a power source and try again.
• Cannot pair with a device:
  • Ensure the headphones are in pairing mode (LED flashing blue and red).
  • Make sure Bluetooth is enabled on your device and it is within range (up to 40 meters, line of sight).
  • Clear previous Bluetooth pairings on your device and the headphones (refer to your device's manual for clearing pairings).
  • Restart both the headphones and your device.
• No sound or low volume:
  • Check the volume levels on both the headphones and your connected device.
  • Ensure the headphones are properly paired and connected.
  • Try playing audio from a different application or device.
• Lip-sync delay (audio not synchronized with video):
  • This issue is common with standard Bluetooth connections. For TV watching, ensure you are using an Avantree FastStream compatible transmitter (e.g., Avantree Ensemble) to minimize delay.
  • Verify that both the headphones and the transmitter are connected using the FastStream codec.
