Samsung does pack a pair of premium Galaxy Buds with their flagship devices, though in pre-orders. And this trend is going on since Note 8 or Note 9. This time, Samsung is going to bundle the Galaxy Buds Beyond along with Galaxy S21 inside the box.
Previously, Samsung used to pack a pair of AKG wired earphones. But after the removal of headphone jack, we have seen the waves of True Wireless Earphones incoming. Do note that the Galaxy Buds Beyond is going to be the successor to the Galaxy Buds Plus.
For the time being, the Galaxy Buds used to come free as a pre-order. But now it will come bundled inside the Galaxy S21 box.
Also the rumor is going on that Samsung will also ditch the charger from inside the box, just like Apple did with iPhone 12 this year. It is possible that Samsung is bundling Buds inside the box to compensate. But you can take this news with a grain of salt for now.
