Pros

  • Natural and pleasant recordings
  • Very good volume performance
  • Great management of artifacts, clean recordings

Cons

  • Severe lack of clarity in recordings
  • Performance in concert use case is a bit underwhelming

The Oppo Find X6 Pro’s audio performance was  very similar to its predecessor’s, the Find X5 Pro, with natural sounding audio but a lack of clarity and brilliance in both playback and recording.

Our experts found the Find X6 Pro’s  recordings to be clean and sufficiently loud, but clarity dropped noticeably at high volume for both recording and playback. With its built-in speakers, the Find X6 Pro delivered fairly consistent results across use cases, making it equally suitable for listening to music, watching movies and gaming. When recording, it did best with the main camera. This said, it was also a decent option for selfie camera and memo recordings.

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 playback, the Oppo Find X6 Pro offered a decent tonal balance, with natural-sounding treble and midrange (although it lacked some clarity and brightness), as well as good bass that only lacked some low-end extension and roundness. Tonal balance was deemed aggressive at maximum volume when listening to music and even more so when gaming, while at soft volume, the lack of clarity and brilliance was accentuated. In terms of dynamics, attack was decent but could have been sharper. The device also provided good bass precision, and punch was correct but did not really leave a true impact. Dynamics qualities were preserved at soft volume, but further flawed at maximum volume because of distortion and compression. The built-in speakers created a fairly wide sound scene and provided quite precise and accurate localizability of individual sound sources. However, voices tended to be perceived further in the distance than on comparison devices, and the depth rendition of the sound scene could have been better.

Our experts found the minimum volume setting to be  a little too quiet, with some softer content not being properly audible. Maximum volume was loud enough, but the volume step distribution was slightly inconsistent. Some distortion and compression at maximum volume were noticed, and the right speaker was too easily occluded when holding the phone in landscape orientation. But the effects on playback quality were only minor.

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.

In recording, our experts found the Oppo’s timbre to be good overall. Tonal balance was quite consistent across use cases and sounded natural, despite a lack of lower treble clarity and an inconsistent upper midrange. This however allowed the background rendition to be quite unobtrusive, and pleasant to listen to. Dynamic performance was good, with a decent signal-to-noise ratio across all use cases and a generally accurate envelope.

When recording video with the main camera in landscape orientation, our testers found audio wideness and localizability of individual sound elements to be satisfying but not quite on the level of the best in class. However, results for both sub-attributes were excellent when recording selfie video in portrait orientation. Distance rendition was generally correct, but voices were often perceived too far away. Volume performance was very good, thanks to relatively loud recordings and a high resilience to high sound pressure levels, making the Find X6 Pro a good option for recording at loud events, such as concerts.

Unwanted audio artifacts were very well under control, with only some compression and light distortion at high sound pressure levels. The Oppo Find X6 Pro proved to be quite performant in the presence of wind. Its recordings preserved intelligibility as long as wind speeds were not too overwhelming. The audio zoom feature was also very efficient, but only for vocal content, as it had trouble isolating musical instruments when zoomed-in.

Here is how the Oppo Find X6 Pro performs in recording use cases compared to its competitors:

The Artifacts score measures the extent to which the recorded sounds are affected by various types of distortions. The higher the score, the less the disturbances in the sound are noticeable. Distortions can occur because of sound processing in the device and the quality of the microphones, as well as user handling, such as how the phone is held.

In this audio comparison, you can listen to the way this smartphone handles wind noise relative to its competitors:
