Background and Identification
The Galaxy Buds2 were announced and released by Samsung alongside two new foldable smartphones in August of 2021, and are a direct replacement for 2020’s Galaxy Buds+. Shaped like smaller Galaxy Buds Pros, some notable features include wireless charging, active noise cancelling, and a five-hour battery life with 15 additional hours of charge in the case with ANC active. Despite the “2” in its name, these are Samsung’s fifth pair of wireless earbuds to date.
The Galaxy Buds2 undercuts the $199 Galaxy Buds+ and $169 Galaxy Buds Live at $149 and come in Olive, Lavender, White, and Graphite.
The Galaxy Buds2 use the BES2500ZP chipset and can be identified by model numbers SM-R177NZGAASA , SM-R177NZKAASA , SM-R177NLVAASA and SM-R177NZWAASA.
