I just purchased the earfun free 2 and I can only get one earbud to work at a time.

I've tried what I saw in the forum about pressing the button for 10s, but still only one earbud works.

Can you help?

Hi Robin,


Thanks for choosing EarFun. Sorry for the inconvenience caused.


Have you removed the insulating film on the earbuds? If not, please kindly remove the insulating film first and then follow the below steps to have a try.


1. Please use the charging cable to charge the case for 2 hours.


2. A. Clean the contacts of the earbuds and the charging case with an alcohol cotton swab; (especially the groove of the earbud contacts);

B. 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. Place both earbuds into the charging case.

Step 3: Keep the charging case open, press and hold the charging case button for at least 8s until both earbuds flash in purple, then the earbuds have been reset successfully.

Step 4: Search and reconnect “EarFun Free 2".


4. We also suggest you try to connect the earbuds to other models of devices to test whether it is still the same situation.


If the above methods still could not solve your issues, please email to our customer service team via or submit the warranty ticket on our official website: EarFun provides 18-month warranty for every product. Your satisfaction is always greatly important to us.
