Oppo Find X5 Audio test

This device has been retested in the latest version of our protocol. Overall, sub-scores and attributes are up to date. For detailed information, check the What’s New article
OTHER AVAILABLE TESTS FOR THIS DEVICE

We put the Oppo Find X5 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

The Oppo Find X5 provides an average audio performance for an ultra-premium device. Its strengths in playback were in listening to music and watching movies, helped by the default activation of Dolby SFX, which brings clarity and brightness to sounds in all use cases. As a recording device, the Oppo did better in memo and meeting room recordings, but when used in conjunction with the camera to record selfies or life videos, the audio scored a little lower.


Key audio specifications include:

  • Stereo speakers, top front-firing, bottom side-firing
  • Hi-Res audio
  • Dolby Atmos
  • 3D audio recording

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.

The playback performance on the Oppo Find X5 was average in timbre, dynamics, spatial and artifacts. The lack of bass and treble brought out all the imperfections of the midrange and resulted in an overall poor timbre performance.  Dynamics was also hampered by the lack of bass. Not only was the low-end lackluster, but it was also quite blurry, affecting bass precision performance. In addition, punch was pretty weak. Spatial performance to be decent, with a perfectly centered stereo sound that provided average wideness in a landscape orientation and good localizability of individual sounds. Unfortunately, the stereo sound does not rotate when the phone is held upside down in landscape orientation. The attribute with the highest score was artifacts, mainly because there were so few of them in playback in most use cases, except in gaming, where speakers were easily occluded.

Here is how the Oppo Find X5 performs in playback use cases compared to its competitors:
Playback use-cases scores


Timbre

104

Oppo Find X5

158

Black Shark 5 Pro

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


Dynamics

114

149

Black Shark 5 Pro

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.


Spatial

107

Oppo Find X5

162

Black Shark 5 Pro

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


Volume

132

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 X5 75.5 dBA 71.3 dBA
Sony Xperia 1 III 74.2 dBA 67.9 dBA
Vivo X70 Pro+ 72.4 dBA 73.8 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:

Artifacts

Asus ROG Phone 5

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.


Recording

How Audio Playback 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 Oppo Find X5’s recording performance was better than Playback. Artifacts outperformed the other attributes in Recording because sounds were clear and free of artifacts even at loud volume.  The lack of clarity in tonal balance affected the device’s  spatial performances. Despite a decent amount of bass,   low-end extension was lackluster, even more so in the electronic concert use case. The selfie and memo recordings showed better timbre performances, with clearer tonal balance and more pronounced high midrange. The stereo scene was particularly narrow in selfie videos. Envelope rendition was deemed inaccurate, but all use cases showed a good signal-to-noise ratio. The lack of clarity in tonal balance and unnatural sound affected background audio, even in the absence of artifacts.

Here is how the Oppo Find X5 performs in recording use cases compared to its competitors:

Timbre

The Timbre score represents how well a phone captures sounds across the audible tonal range and takes into account bass, midrange, treble, and tonal balance. It is the most important attribute for recording.

Life video frequency response


Dynamics

118

Oppo Find X5

146

Black Shark 5 Pro

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 Sound-to-Noise Ratio (SNR), for example how loud the main voice is compared to the background noise.


Spatial

116

Oppo Find X5

157

Asus ROG Phone 5

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


Volume

145

Oppo Find X5

170

Black Shark 5 Pro

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:
Meeting Life Video Selfie Video Memo
Oppo Find X5 -23.4 LUFS -20 LUFS -18.1 LUFS -18.4 LUFS
Sony Xperia 1 III -30.5 LUFS -22.4 LUFS -20.2 LUFS -21.3 LUFS
Vivo X70 Pro+ -23.1 LUFS -18 LUFS -16.7 LUFS -18.6 LUFS


Artifacts

134

Oppo Find X5

145

Black Shark 5 Pro

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.

Background

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.
