Common questions about manuals, registration, and support for this brand.
Take both earbuds out of the charging case; they should power on and enter pairing mode automatically. Open Bluetooth settings on your device, search for the model name (e.g., 'A90 Pro' or 'HD 65'), and select it to connect.
This often happens if the earbuds fail to sync with each other. Try putting both earbuds back into the charging case, closing the lid, and waiting for a few seconds. If that doesn't work, clear the Bluetooth pairing from your phone and perform a factory reset as described in your specific user manual.
Check if the charging contacts on the earbuds or the pins in the case are dirty or oxidized. Clean them gently with an alcohol wipe. Also, ensure the charging case itself has battery power by connecting it to a USB-C cable.
