Oppo Find N2 Flip Audio test

We subjected the Oppo Find N2 Flip to our rigorous SBMARK audio test suite to measure its performance both when recording sound using its built-in microphones, and when playing audio through its speakers.

In this review, we’ll analyze how it performed in a variety of tests and several common use cases.

Overview

Key audio specs include:

• Two speakers (bottom side and top front)
• No audio jack output

With a SBMARK audio score of 131, the Oppo Find N2 Flip performed quite well in our tests. As a playback device, it wasn’t quite as good as the foldable N2 with its large size in its unfolded state, but it had the edge in recording, delivering surprisingly good results.

The playback experience with the built-in speakers was virtually artifact-free and offered good localizability to individual sound sources. The sound signature was a bit dark, though. Overall, the Oppo performed better when watching movies and playing games, scoring slightly lower in the music use case. As a recording device, it performed equally well in all use cases, delivering a pleasant sonic signature, even at high sound pressure levels, such as at concerts and performances. The stereo recordings were also very engaging.

In audio playback, the Oppo Find N2 Flip delivered decent tonal performance overall, although it lacked high-end and low-end extension. This also emphasized the somewhat dull treble sound and not particularly strong bass. While the rendering of the attack lacked sharpness, it still worked decently. Punch and Bass Precision were a bit underwhelming, but on the plus side, the secondary attributes of the Dynamics were pretty consistent across all volume levels.

The device’s built-in speakers produced a fairly large soundstage where individual sound sources were easy enough to pinpoint. Distance was accurately rendered but depending on the audio file being played the depth rendering could have been better at times. Our experts also found the minimum volume to be a little too low for highly dynamic content such as classical music, and objective measurements have shown a lack of consistency in volume distribution. Maximum volume was quite good, however, and the Oppo was virtually free of unwanted audio artifacts, with the exception of accidental occlusions from the built-in speakers, which can be common.

Here’s how the Oppo Find N2 Flip fares in playback use cases compared to its competitors:

Here are some sound pressure levels (SPL) measured while playing our sample recordings of hip-hop and classical music at maximum volume:

The following graph shows the gradual changes in volume from minimum to maximum. We expect these changes to be consistent across the range, so that all volume steps match user expectations:

The audio recordings of our tests highlighted the Oppo’s excellent tonal rendering, thanks to an exceptional tonal balance that characterized a bright and natural sound delivery with considerable warmth. The rich treble has been combined with a good midrange and natural bass rendition. Dynamic performance was good too, with a natural envelope and sharper attack than the Find N2.

The breadth of recording was excellent across all use cases, and even more immersive than the foldable Find N2. In addition, the distance rendering was very good and the excellent locateability made it easy to locate sound sources in the scene. The volume of the recording was quite high and the Oppo did a good job of controlling unwanted artifacts in common use cases. Our experts only noticed distortion and pumping when recording louder sounds, like screaming vocals. The background was clear and well rendered.

Here are the sound levels recorded in the audio and video files, measured in LUFS (Loudness Unit Full Scale); for reference, we expect volume levels to be above -24 LUFS for recorded content:
