Where is the noise in the headphones?

Question

macbook

Hello. Today I noticed such an interesting thing, in the right earpiece (earpods headphones) there is extraneous noise, but what is strange:
the laptop is charging, if I turn off the charging, the noise disappears.
the laptop is charging and if, for example, I touch any metal part on the laptop case with my finger, the noise gets in.
Tell me where the problem is and how to solve it?
Thanks in advance.

Answer 1

It was like this - it turned out to be a defective charger (noise was heard from the case, like a shorting contact - the same sound was heard in the headphones)
But first, it's worth checking on a socket with good grounding.

Answer 2

Poor nutrition judging by the symptoms. For example, there is no grounding, the role of which is performed by a person.

Answer 3

Usually, when buying apple products, they give out a special grounding slave who must hold a finger. Contact the service if you have not been given this.

Answer 4

the same garbage ....; D infuriates. on iMac and MacMini....
on Mabook probably there is no such thing or I don’t notice it because my hands are constantly on the case
