Samsung has unleashed the Galaxy Buds 2 in 2 limited-edition co-branded forms on its home market of South Korea. One is a Pokémon-themed bundle that could go with a matching Galaxy Z Flip3 from an earlier event, whereas the other is one for fans of soft drinks. They both largely entail a new carrying-case for the TWS accessories in question.
