We put the Oppo Find X6 through our rigorous DXOMARK Audio test suite to measure its performance both at recording sound using its built-in microphones, and at playing audio back through its speakers.
In this review, we will break down how it fared in a variety of tests and several common use cases.
Overview
Key audio specifications include:
- Two speakers (Top side, bottom side)
- No Jack audio output

Playback
Cons
- Muffled tonal balance across all use cases
- Unbalanced stereo, leaning to the right in landscape orientation
Recording
Pros
- Pleasant and natural recordings
- Good Volume performance
- Artifacts well under control
Cons
- Lack of brightness in recordings
- Slightly underwhelming when recording loud events, such as concerts
In the DXOMARK Audio test, our experts found the Oppo Find X6 to be a good device for both audio playback and recording. Overall performance was very similar to the Find X6 Pro. Results were slightly better when recording sound, and slightly lower in playback. As a playback device, the Find X6 performed best when watching movies and playing games, but results were almost on the same level for listening to music content. Recordings were best with the main camera and memo app, but front-camera results were not far off.
The device offered a pleasant sonority and loud sound, both when playing back audio through the built-in speakers and when recording audio. However, our experts also found the device to sound slightly dull in playback as well as recording. They also noticed bass distortion with the built-in speakers.
Test summary
About DXOMARK Audio tests: For scoring and analysis in our smartphone audio reviews, DXOMARK engineers perform a variety of objective tests and undertake more than 20 hours of perceptual evaluation under controlled lab conditions.
(For more details about our Playback protocol, click here; for more details about our Recording protocol, click here.)
The following section gathers key elements of our exhaustive tests and analyses performed in DXOMARK laboratories. Detailed performance evaluations under the form of reports are available upon request. Do not hesitate to contact us.

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.
Listen to the tested smartphone’s playback performance in this comparison with some of its competitors:

Here is how the Oppo Find X6 performs in playback use cases compared to its competitors:
Playback use-cases scores

The Timbre score represents how well a phone reproduces sound across the audible tonal range and takes into account bass, midrange, treble, tonal balance, and volume dependency. It is the most important attribute for playback.
Music playback frequency response
A 1/12 octave frequency response graph, which measures the volume of each frequency emitted by the smartphone when playing a pure-sine wave in an anechoic environment.

The Dynamics score measures the accuracy of changes in the energy level of sound sources, for example how precisely a bass note is reproduced or the impact sound from drums.

The sub-attributes for spatial tests include pinpointing a specific sound's location, its positional balance, distance, and wideness.

The Volume score represents the overall loudness of a smartphone and how smoothly volume increases and decreases based on user input.
Here are a few sound pressure levels (SPL) measured when playing our sample recordings of hip-hop and classical music at
maximum volume:
|
Hip-Hop |
Classical |
| Oppo Find X6 |
74.1 dBA |
72.3 dBA |
| Oppo Find X6 Pro |
74.5 dBA |
72.4 dBA |
| Samsung Galaxy S23 |
73.9 dBA |
69.1 dBA |
The following graph shows the gradual changes in volume going from
minimum to maximum. We expect these changes to be consistent across the range, so that all volume steps correspond to users’ expectations:
Music volume consistency
This line graph shows the relative loudness of playback relative to the user selected volume step, measured at different volume steps with a correlated pink noise in an anechoic box recorded in axis at 0.20 meter.

The Artifacts score measures the extent to which the sound is affected by various types of distortion. The higher the score, the less the disturbances in the sound are noticeable. Distortion can occur because of sound processing in the device and because of the quality of the speakers.
Playback Total Harmonic Distortion (Maximum Volume)
This graph shows the Total Harmonic Distortion and Noise over the hearable frequency range.
It represents the distortion and noise of the device playing our test signal (0 dB Fs, Sweep Sine in an anechoic box at 40 cm) at the device's maximum volume.

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

The Dynamics score measures the accuracy of changes in the energy level of sound sources, for example how precisely a voice's plosives (the p's, t's and k's, for example) are reproduced. The score also considers the Signal-to-Noise Ratio (SNR), for example how loud the main voice is compared to the background noise.

The sub-attributes for spatial tests include pinpointing a specific sound's location, its positional balance, distance, and wideness on the recorded audio files.
Recording directivity
Directivity graph of the smartphone when recording test signals using the camera app, with the main camera. It represents the acoustic energy (in dB) over the angle of incidence of the sound source. (Normalized to the angle 0°, in front of the device.)

The Volume score represents how loud audio is normalized on the recorded files and the how the device handles loud environments, such as electronic concerts, when recording.
Here are the sound levels recorded in the audio and video files, measured in
LUFS (Loudness Unit Full Scale); as a reference, we expect loudness levels to be above -24 LUFS for recorded content:

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:

Background evaluates how natural the various sounds around a voice blend into the video recording file. For example, when recording a speech at an event, the background should not interfere with the main voice, yet it should provide some context of the surroundings.
