I just received EarFun Air Pro 2 today and set them up. They are working, however, the right earbud has a constant metallic buzzing/reverb/feedback sound as music plays. The left earbud, when used alone, sounds clean. 

Disconnecting/reconnecting didn't fix.

Same on WiFi or 5G

Any ideas? Thanks!

Hi friend, 


Thanks for choosing EarFun. Sorry for the inconvenience caused. 


Does the noise occur in all three modes?


We kindly suggest you reboot your device and then reset and reconnect the earbuds as 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 earbuds have been reset successfully.

Step 4: Search and reconnect “EarFun Air Pro 2".


We also suggest you try to connect the earbuds to other models of devices to test whether it is still the same situation. Please also check whether the microphone holes are blocked. 


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.
