I think you need an amplifier connected in series with this module output to have enough power to drive the earbuds

 

I agree with @albo.c, I can't find the output specifications online but all the applications treat the board's output as line level. You will need a small amplifier to drive the headphones.

 

where did you connect the ground of the earbuds? I guess it should go to AGND
