You can buy wired Type C AKG earphones, that come in-box in Galaxy Note 10. You can also buy wireless Level U earphones by Samsung. But the best ones are Galaxy Buds by Samsung. They're seamless and pretty useful.
Better buy a Type c to 3.5mm dongle and purchase Sony Earphone. Also Samsung Level u sound very bad. I'm a amazon reviewer and these level u was available for review. But i didn't take. I'm using Oneplus Bullet Wireless 2 and it works perfectly. Also Galaxy buds are not good if you take lots of calls. Is you are looking for tws then Grab Airpods 2.
