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: Unpair EarFun Free from your Bluetooth-enabled device and delete the old connection on your device.
Step 2: Pick up the earbuds from the case and press the buttons for 2s at least to power off until they flash in red.
Step 3: Press and hold the button on each earbud simultaneously for at least 8s until they flash in purple (Do press until they flash in purple. If not, they aren’t reset successfully.)
Step 4: Place them back into the case and remove them again to start reconnecting.
Below is the video link showing the complete steps of resetting and reconnecting for your ref.
