Left bud not working air pro 4

Hi Friend,

Thanks for choosing EarFun. Sorry for the inconvenience caused.

As for the issue you encountered, we kindly suggest you try to reboot your Bluetooth device (phone, computer...) and reset the earbuds.

Step 1: Delete the old connection from the Bluetooth device.

Step 2: Put both earbuds into the charging case, close the lid, and wait for 30 seconds.

Step 3: Keep the charging case open, then press and hold the button on the case for at least 10 seconds until both earbuds status LED indicators inside the case flash white rapidly. The earbuds have been reset successfully.

Step 4: Reactivate Bluetooth to reconnect "EarFun Air Pro 4" until the white light flashes slowly.

If the above method still could not solve your issues, please kindly send us your order number to our customer service team: service@myearfun.com or submit the warranty ticket on our official website: https://www.myearfun.com/process-warranty.

Sincerely,

EarFun
