DisplayWe 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
Scoring
Sub-scores and attributes included in the calculations of the global score.
Oppo Find N2 Flip
43rd
27th
Playback
Pros
- Free of unwanted audio artifacts
- Good localizability of sound sources in the audio scene
- Accurate distance rendition
Cons
- Inconsistent tonal balance
- Rounded attack and weak punch
- Lack of depth
Recording
Pros
- Natural timbre
- Excellent wideness and localizability
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.

Playback
Oppo Find N2 Flip
163
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.
Listen to the tested smartphone’s playback performance in this comparison with some of its competitors:
Timbre
Oppo Find N2 Flip
158
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.
Dynamics
Oppo Find N2 Flip
149
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
Oppo Find N2 Flip
162
The sub-attributes for spatial tests include pinpointing a specific sound's location, its positional balance, distance, and wideness.
Volume
Oppo Find N2 Flip
162
The Volume score represents the overall loudness of a smartphone and how smoothly volume increases and decreases based on user input.
| 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 |
Artifacts
Oppo Find N2 Flip
157
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.
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
Oppo Find N2 Flip
157
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:
Timbre
Oppo Find N2 Flip
147
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.
Dynamics
Oppo Find N2 Flip
146
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
Oppo Find N2 Flip
159
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
Oppo Find N2 Flip
170
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.
| 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 |
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
Oppo Find N2 Flip
166
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.
