Sound and Audio
The audio output of the Xiaomi Mi 9 is satisfactory, with a loudspeaker that performs well in various volume settings. The in-call voice quality registers at a modest 70 dB, noise at 74 dB, and ring tone peaks at 81 dB. While lacking a dual stereo speaker setup and a headphone jack, audio playback remains clear, though audiophiles may prefer external options for a richer audio experience.
