On Macbook Pro, whenever I plug my headphones in and start to play sound. A background hissing begins,
now I cant really hear it under the music unless its low, but when i stop playing the music I hear the hissing.
Then it goes away after 30 seconds or so if I dont play any audio.

Does anyone know how I can resolve this?

Then also whenever I plug the charger in and my headphones, I hear a staticky sound, though I suspect its because of thencharger that's not official apple.

Good chance getting a FiiO E10K or Schiit Fulla would clean up the audio noise.

Yeah, sounds like the noise is coming from the Macbook itself; an external DAC would solve this.
You should try to see if others have this issue with the same Mac

Not the same Mac but I had a similar issue on a Late 2012 Mac Mini. External DAC cleaned it right up.

Which 1 do you have?

First one I bought was a Fiio 07K. Solved the issue no problem. Sold the Fiio, now have a Modi 2/Vali stack.
