Microphone buzzing when I charge my ps4 controller?

My microphone is buzzing when I charge my ps4 controller. But if I do not invite him, everything is normal.

Then the charger interferes and sparks in between

Can you do something about it?

Where is the microphone connected? If possible, keep a distance between the two devices, but it will probably disturb the signal.

Hang a ferrite core on the cable.

I have a headset with 2 latches connected in a 2 to 1 adapter on the controller

Not really. The disturbance is called "50Hz hum" and is likely in your case wired.
Just do not charge while using the headphones.

The PS4 controller will go off after max. 4 hours.

Then do not gamble that long or buy your PC like any other decent gambler.
