I connect samsung s20 to mojo to a50s, listen to 4.4mm out with iem. There's buzzing background sound. But if I touch the chassis of mojo or a50s or iem cable, the buzzing stopped.

But on the same setup with headphone, there is no buzzing.

Wonder if this is due to dirty power point? So I plug the power adaptor into another wall point, buzzing get even worst ..

Anyone can advise?
