Troubleshooting
If you encounter issues with your Tronsmart Onyx Ace Pro earbuds, try the following solutions:
- Earbuds not pairing: Ensure both earbuds are charged. Place them back in the case, close it, then open it again to re-enter pairing mode. Make sure Bluetooth is enabled on your device and no other devices are connected to the earbuds.
- Only one earbud working: Place both earbuds back into the charging case, close the lid, and then open it again. This often re-syncs them. If the issue persists, try resetting the earbuds (refer to the product's specific reset instructions if available, or try "One-key Recovery" if the product supports it).
- Poor sound quality: Ensure the earbuds are clean and free of debris. Check your device's volume settings. Move closer to your connected device to avoid interference.
- Earbuds not charging: Clean the charging contacts on both the earbuds and the case. Ensure the charging cable and power source are working correctly.
- Low latency gaming mode not working: Ensure the mode is activated correctly by long-pressing the earbud for 3 seconds.
