Hi friend,
Thanks for choosing EarFun. Sorry for the inconvenience caused.
As for the issue you encountered, we kindly suggest you try the below steps.
1. Please use the charging cable to charge the case for 2 hours.
2. A. Use a toothpick to gently clean the metal contacts on the earbuds and charging case to avoid dust or wax stains;
B. Clean the contacts of the earbuds and the charging case with an alcohol cotton swab; (especially the groove of the earbud contacts);
C. Rub them with clean napkins, press the earbuds with forces to eliminate loose contact with the case and charge them around 1.5 hours to try it out. (Ensure the case has enough battery life simultaneously).
3. Reboot your device and then reset and reconnect the earbuds per the updated steps:
Step 1. Delete the old connection from the Bluetooth device.
Step 2. Keep the earbuds out of the charging case, touch and hold the earbuds button for at least 8 seconds to power off both earbuds and make sure both earbuds are powered off.
Step 3. In power-off mode, touch and hold the button on each earbud at the same time for at least 10 seconds until they flash alternately in blue and white, then earbuds have been reset successfully.
Step 4. Search and reconnect "EarFun Air Pro SV".
4. We also suggest you try to connect the earbuds to other models of devices to test whether it is still the same situation.
