Airfun pro 4

Thanks for choosing EarFun. Please kindly send your order number to our customer service team for further assistance: service@myearfun.com.

I I think I will return the headphones to the manufacturer, I no longer have the strength to look for a solution. I have a Oneplus12 and in the Earfun app I want to enable LDAC. But it keeps telling me to turn off dual linking. I did that and it still doesn't work! This means that the manufacturer promised an LDAC codec, and it doesn't work. Please take these headphones away since you are providing something that doesn't work!

I CANNOT POST NEW DICUSION!!!!
