I can only connect with only one side of my earfun air pro

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 for 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. Place both earbuds into the charging case. Please confirm that the indicator light flashes in white once you put the earbuds into the charging case.

Step 3. Keep the charging case open and double press the charging case button, the pairing indicator will flash white rapidly, just waiting for the flash white transfer to flash white and green alternately, then the earbuds have been reset successfully.

Step 4. Search and reconnect “EarFun Air Pro".

Below is the video link showing the complete steps of resetting and reconnecting for your ref.
