Unstable connectivity on LC3 codec with Pixel 7 and EarFun Air Pro 3

I have recently tried the LC3 codec on my Pixel 7 device with my EarFun Air Pro 3.

After activating the LC3 codec on my phone it worked for a while, but I started experiencing connection dropouts.

Eventually after putting the buds in the case and getting them out they would not play any sound anymore using the LC3 codec.

So I am back on APTX adaptive again and the buds again work  as normal.

Also when I used the LC3 codec I don't have any access to the EarFun app.
Can this be solved via a firmware update? Right now I can't really stability use my buds using the LC3 codec.

Hi friend, 


Thanks for choosing EarFun. Sorry for the inconvenience caused. 


 About the problem that the earbuds go silent when LE audio is turned on, our engineers tested and found that it may be a problem with the mobile phone: the mobile phone actively disconnects the audio connection with the earbuds, which cannot be controlled by the earbuds. Hence, we are afraid that this problem can only be solved by updating and repairing LE audio protocols on the mobile phone.  Sorry for any inconvenience caused. 


As for the app connection issue, since LE audio is a very new technology, we are analyzing the LE Audio compatibility issue and we will solve it through OTA in the future. 


 If you have any questions, please 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.

Hi EarFun CS Team,

May I know what device you use to test the earbuds?  I really want to try LE audio but also looking for a reliable device to do so.
