Ok so here's what happened

1. I lost the case but then found it a few months later. Working fine when I lost them.

2. I put them in and the left one was working and the right wasn't. I cleaned my ears and adjusted the right one for a while and it finally worked after 10 mins

3. Then the left one stopped working. I couldn't get it to start working again. I've reset them multiple times, and it still won't work and it's very frustrating 

please help

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. 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, then touch and hold the button on each earbud at the same time for at least 10s until they flash alternately in blue and white then earbuds have been reset successfully.

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


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