Windows 10: why does my headphones buzz when i plug them in my pc

when i plug basically any headset into my pc theres a buzzing sound and there cna be peeping sounds too.. and something else that ive noticed is that its like i can hear the things i do on my computer in my headphones like when i move my mouse i can hear the buzzing almost follow my mouse in a way. like i can control the buzzing with what i do on my pc. With my old headset i could turn down the sound on the headphones themselves which helped the buzzing go away the lower the sound but on my new phones i dont have that option. Can anyone tell me what it might be?

Buzzing Sound in Background of Audio

Hello,

When my headphones are plugged into my laptop, there is a buzzing sound in the background of the audio. I know it’s not a problem with the headphones, because I tested it with my iPad and it worked perfectly. How do I stop this buzzing sound? Any suggestions
