It is important to understand that the update process for AirDots Pro 2 is different from other Xiaomi models (for example, AirDots 3 Pro or Buds 4). There is no classic OTA via smartphone, only working with proprietary applications Mi Home or Mi Fit, and in some cases will require manual firmware via PC. We tested all methods on current versions of the software (2026) and collected step-by-step instructions taking into account typical user errors.
