OK. Wasn't sure. That I don't know. I still have mine from my Note and use it when needed. It I have my original Samsung earbuds I use.
Here is the Samsung version on amazon
SAMSUNG EE-UC10JUWEGUS USB-C to 3.5mm Headphone Jack Adapter for Note10 and Note10+ (US Version with Warranty) https://www.amazon.com/dp/B07VF6NSZZ/ref=cm_sw_r_apan_i_R6KA3H94AWZDABT6TB5Q?psc=1
I don't think that's correct. The dongle has to have a DAC to work through the usbC port.
Here's Samsung's
I have one, it's nothing special.
I prefer this one
This works well with my Pixel phone: https://www.amazon.com/gp/aw/d/B07VF6NSZZ
Just buy the Samsung Original Adapter and call it a day!
