Hi Friend,
Thanks for choosing EarFun. Sorry for the inconvenience caused.
Could you please send us your order number to check first?
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 for around 1.5 hours to try it out. (Ensure the case has enough battery life simultaneously).
3 Reboot your phone and reset and reconnect the earbuds again.
Step 1: Delete the old connection from the Bluetooth device.
Step 2: Place both earbuds into the charging case.
Step 3: Keep the charging case open, touch and hold the button on each earbud simultaneously for at least 10s until they flash in purple, then earbuds have been reset successfully.
Step 4: Search and reconnect “EarFun Free Pro".
Below is the video link showing the complete steps of resetting and reconnecting for your ref.

If the above method still could not solve your issues, could you please kindly shoot a video for us to show the changes in the LED lights of the earbuds and the charging case by taking the earbuds out and then putting them back into the case to reset and email our customer service team via service@myearfun.com or submit the warranty ticket on our official website: https://www.myearfun.com/process-warranty.
EarFun provides an 18-month warranty for every product. Your satisfaction is always greatly important to us.
