The design of the adapter is pretty straightforward, as you would expect. The white paint job means the Galaxy Note 10's other in-box accessories will likely be white as well, just like the accessories you get with the Galaxy S10 lineup. Samsung isn't bundling a 3.5mm to USB-C adapter with the Galaxy Tab S6, but the company isn't expected to make it a separate purchase for Galaxy Note 10 and Note 10+ buyers. The devices will also be accompanied by USB-C earphones, possibly with noise cancellation support in addition to the AKG-tuned sound.
And Samsung will probably give away free Galaxy Buds with Galaxy Note 10 and Note 10+ orders. It did so for the Galaxy S10 series, which does have a headphone jack, so it wouldn't be unreasonable to assume the Korean giant will have a similar offer for the upcoming Note flagships.
Will you be buying the Galaxy Note 10 or Note 10+ even if there's no headphone jack, or is the dongle life something you simply cannot tolerate?
