If you are still chasing the buzz, I'd recommend getting something like this : https://www.amazon.com/dp/B09B9PCYSS/ref=sspa_mw_detail_2?ie=UTF8&psc=1&sp_csd=d2lkZ2V0TmFtZT1zcF9waG9uZV9kZXRhaWwp13NParams
There are significantly better versions of this, but TRRS receiver with USB plug should solve all of your problems (assuming it works as well as more expensive ones)
That would allow you to plug your sony earbuds or the cheap headphones provided into the usb audio adapter/amp that you can see in the pictures.
Good luck🤞
