Oppo Find N2 Flip Audio test

OTHER AVAILABLE TESTS FOR THIS DEVICE

We put the Oppo Find N2 Flip 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 (bottom side and top front)
  • No jack audio output

Pros

Cons

  • Lack of low-end extension and slightly inconsistent bass rendition when recording loud content, such as concerts
  • Signal-to-noise ratio could be better in urban scenarios, background noise is quite intrusive

With a DXOMARK Audio score of 131, the Oppo Find N2 Flip delivered a pretty good performance in our tests. As a playback device, it was was not quite as good as the foldable N2 with its large dimensions in its unfolded state, but it had the edge in recording, delivering surprisingly good results.

The playback experience with the built-in speakers was pretty much free of artifacts and offered good localizability on individual sound sources. The sound signature was a touch dark, though. Overall, the Oppo did best when watching movies and gaming, scoring slightly lower in the music use case. As a recording device, it did equally well across all use cases, delivering a pleasant sound signature, even at high sound pressure levels, for example at concerts and shows. Stereo recordings were very immersive as well.

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.

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 Audio Playback the Oppo Find N2 Flip delivered an overall decent Timbre performance, although it lacked high-end and low-end extension. This also emphasized treble sounding a little dull and bass not being particularly strong. While attack rendition lacked sharpness, it still did decently. Punch and Bass Precision were a bit underwhelming on the other hand, but on the plus side, Dynamics sub-attributes were pretty consistent across all volume levels.

The device’s built-in speakers produced a decently wide sound scene in which individual sound sources were quite easy to locate. Distance was rendered accurately but, depending on the audio file played back, depth rendition could sometimes have been better. Our experts also found the minimum volume step a little too quiet for highly dynamic content such as classical music, and objective measurements showed a lack of consistency in volume step distribution. Maximum volume was pretty good, though, and the Oppo was pretty much free of unwanted audio artifacts, save for the accidental occlusions of the built-in speakers, which can be common.

Playback use-cases scores

Timbre

116

Oppo Find N2 Flip

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

113

Oppo Find N2 Flip

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

130

Oppo Find N2 Flip

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

123

Black Shark 5 Pro

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 N2 Flip 75.3 dBA 72.2 dBA
Samsung Galaxy Z Flip4 73.6 dBA 68.4 dBA
Apple iPhone 14 74.8 dBA 71.9 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.

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.

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.

Recording

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.

Audio recordings from our tests highlighted the Oppo’s excellent timbre performance, thanks to an outstanding tonal balance that featured a bright and natural sound rendition with noticeable warmth. Rich treble was combined with a good midrange and natural bass rendition. Dynamics performance was good, too, with a natural envelope and sharper attack than the Find N2.

Recording wideness was excellent across all use cases, and even more immersive than on the foldable Find N2. In addition, distance rendition was very good and excellent localizability allowed for easy pinpointing of sound sources in the scene. Recording loudness was loud enough, and the Oppo did a good job at controlling unwanted artifacts in common use cases. Our experts only noticed distortion and pumping when recording louder sounds, such as shouting voices. Background was clear and well-rendered.

Here is how the Oppo Find N2 Flip performs in recording use cases compared to its competitors:

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


Spatial

147

Oppo Find N2 Flip

159

Vivo X Fold

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.)

Volume

136

Oppo Find N2 Flip

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 N2 Flip -24.9 LUFS -22.2 LUFS -19.1 LUFS -18.8 LUFS
Samsung Galaxy Z Flip4 -25.2 LUFS -21.5 LUFS -19.7 LUFS -21.6 LUFS
Apple iPhone 14 -23.8 LUFS -22.5 LUFS -20.5 LUFS -18.7 LUFS

Artifacts

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

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.
