Xiaomi CC9 Pro Premium Edition performs poorly on DXOMARK Audio test

DxOMark is a well-known camera evaluation agency that recently extended its practice to audios. Recently, it released the audio score for the Xiaomi CC9 Pro exclusive version. According to the DxOMark team, the audio score of the Xiaomi CC9 Pro Premium Edition is 54 points. This is a relatively low score amongst the devices it has tested so far. The overall performance of the single speaker of Xiaomi CC9 Pro Premium Edition is pretty good. However, the sound field is narrow, unbalanced, and the bass is severely insufficient. In addition, the sound is extremely distorted at maximum volume. However, there is very little sound loss at soft to nominal volume.

Audio specifications:

  • Single speaker (bottom left)
  • Headphone jack
  • Hi-Res audio

The DxOMark team believes that the most obvious flaw of the Xiaomi CC9 Pro Premium Edition is the single speaker. This configuration makes it sound unnatural when playing music and movies, and it can cause problems when playing games. In addition, this device also includes shortcomings such as insufficient bass, recorded stereo inversion, and severe distortion at maximum volume.

    If you need to explain who DxOMark is, they’re likely not such a renowned organization. 🤔
