So I got this ESR USB-C adapter (link below). It has been pretty good. No static noise while charging. It offers Fast Charging, but I often had to plug it in, then unplug it, then plug it in once more to get the fast charging to work. This does not support "Super Fast Charging" that the charger in the S20 box provides. Another odd thing is that the phone shows an android system notification, as if the phone were plugged into a computer and asks you what you want to do with the USB connection. I will post a screen shot later. Overall, this seems like it may be the best option. I would love to see Samsung release an official adapter to accomplish this use case.

I just found another adapter highly reviewed on Amazon. Slightly more expensive than the previous one I posted. I impulse bought it and will report back when I get it on Friday. https://www.amazon.com/gp/product/B07SM5MQN8/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
Maybe just get some Bluetooth headphones with AptX or LDAC support?
Otherwise see this one (PD 2.0 and QC2.0 fast charging): https://www.amazon.com/ESR-Headphone-Earphones-Headphones-Compatible/dp/B07SM5MQN8
This one works for me: https://www.amazon.com/gp/product/B07SM5MQN8/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
It's expensive, but it has a charging port as well and its sound quality is amazing, actually a big step up from my old S10's headphone jack.
