7. Troubleshooting

If you encounter issues with your HAOYUYAN T16 Wireless Earbuds, refer to the following common solutions:

7.1 Connection Issues

• Earbuds not pairing: Ensure both earbuds are charged. Place them back in the case, close the lid, then open it again to re-enter pairing mode.
• Cannot find "HAOYUYAN T16" in Bluetooth list: Make sure Bluetooth is enabled on your device and the earbuds are in pairing mode. Try turning Bluetooth off and on again on your device.
• Only one earbud working: Place both earbuds back into the charging case, close the lid, and then take them out again. This often resynchronizes them.
• Intermittent connection: Ensure you are within the 10-meter Bluetooth range and there are no significant obstacles between the earbuds and your device. Avoid strong electromagnetic interference.

7.2 Audio Issues

• No sound: Check the volume level on both your device and the earbuds. Ensure the earbuds are properly connected to your device.
• Low volume: Increase the volume on your device and using the earbud touch controls. Ensure ear tips are correctly seated in your ear canal for a good seal.
• Poor sound quality: Ensure the earbuds are clean and free of debris. Try different ear tip sizes for a better fit.

7.3 Charging Issues

• Earbuds not charging in case: Ensure the charging contacts on the earbuds and in the case are clean and dry. Make sure the earbuds are correctly seated in the case.
