Playback

Pros

Cons

  • Lack of low-end extension and bass strength
  • Stereo balance skewed to the right, restricting wideness
  • Lack of intelligibility at softer volumes

Recording

Pros

  • Very good spatial performance
  • Good tonal balance across all apps
  • Good dynamics performance

Cons

  • Not very suitable for recording at high sound pressure levels
  • No audio zoom feature
  • Lack of wind noise reduction

With a DXOMARK Audio score of 134, Xiaomi 13 performed very well in our tests, making the device a great option for audio-focused smartphone users. In playback, it delivered the best results when gaming and watching movies, but it  did not disappoint in the music use case either. The built-in speakers offered a rich and pleasant sound signature, but the stereo balance was somewhat off-centered, which also restricted the wideness of the projected sound scene among other impediments.

In recording, the Xiaomi 13 provided excellent results across all use cases, offering good tonal balance, dynamics and spatial performance. Although heavy compression was noticeable when recording loud sources such as concerts, it didn’t affect quality too much. Additionally, the recording experience could have been enhanced further with an audio zoom feature and an improved handling of wind noise.

How Audio Playback score is composed

DXOMARK engineers test playback through the smartphone speakers, whose performance is evaluated in our labs and in real-life conditions, using default apps and settings.

In our tests, the Xiaomi 13 performed well as a playback device. Timbre performance was good, with a nice tonal balance, despite a slight lack of brightness and low-end extension. Midrange sounded clean and natural. Dynamics were good, too, thanks to sharp and accurate attack, powerful punch and good bass precision. Spatial performance was only average, due to stereophonic balance being skewed towards the right, which also impaired the wideness of the sound scene. This issue was most noticeable in the music use case, but it also had the underlying consequence of making the device more sensible to hand occlusions while gaming. Localizability of individual sound sources was also somewhat blurry, but both distance rendition and depth were good.

Our experts found the minimum volume to not be properly tuned. Low-volume passages in highly dynamic audio content were difficult to hear properly. Maximum volume, on the other hand, was loud enough. Unwanted audio artifacts were overall well under control. The testers only noticed some slight pumping and distortion at maximum volume. It is also worth mentioning that the UI of the default music player froze on several occasions, such as when waking the device up from sleep; audio continued to play while the app was unresponsive, disrupting the listening experience. In addition, the right speaker seemed to be easily occluded by a natural hand position when gaming. Since the right speaker was carrying out most of the audio signal (as the stereo balance was skewed), its occlusion changed both volume and timbre quite dramatically in our tests.

How Audio Recording score is composed

DXOMARK engineers test recording by evaluating the recorded files on reference audio equipment. Those recordings are done in our labs and in real-life conditions, using default apps and settings.

The Xiaomi 13 also did well in recording. Timbre was pleasant in all use cases, with a slight upper-mid boost highlighting intelligibility. When recording with the main or selfie camera, treble was clear but lacked high-end extension a little bit. Midrange sounded natural, despite a slight lack of low midrange warmth, noticeable on voices. Dynamics were good as well, with an accurate envelope allowing for clear comprehension of voices. Signal-to-noise ratio could have been better, though, especially in urban scenarios where the background could be a touch too intrusive.

The device recorded a very wide and immersive sound stage, with an accurate representation of the scene. This was especially true when recording with the main camera. Localizability was deemed precise and distance rendition realistic. Recording volume was loud enough, but there was some fairly extreme pumping at high sound pressure levels, impairing the dynamic envelope — although the impact on general audio quality was negligible. Background rendition was good, with a nice tonal balance, but when recording with the memo app outdoors, the experts noticed unstable background filtering.

Here is how the Xiaomi 13 performs in recording use cases compared to its competitors:
