The Galaxy Buds 2 Pro is Samsung’s first set of truly wireless earbuds that use a Bluetooth 5.3 chip. They are also the company’s first earbuds to support Samsung Seamless Codec HiFi, the South Korean firm’s near-lossless audio codec. They support 24-bit wireless audio transmission, so if you have access to Hi-Res Audio tracks, you can listen to them in near-lossless quality. However, this feature only works when the Galaxy Buds 2 Pro is paired with a Galaxy device running One UI 4.0 (or newer).
