As we mentioned in the test, the Galaxy Buds2 Pro advocate a spatialized audio function with support for multichannel surround and 3D tracks (beyond the “360” suggested by the name of this function). When playing content with an appropriate audio track, the headphones would be able to recreate an immersive spatialization thanks to binaural virtualization, with the added bonus of a head movement tracking option to make the experience as convincing as possible. . If you have already heard this somewhere, it is normal, since it is on this same principle that Apple’s Audio Spatial is based, to cite only this example.
How does this work in practice? First, a Samsung terminal under OneUI 3.1 is required to activate the function, while monitoring requires OneUI 4.1.1 or higher. The option is manually activated in the main menu of the Galaxy Wearable application, and it is possible if necessary to deactivate the option of tracking head movements. Contrary to certain cases, the signal processing is not applied in an intelligent way: it remains permanently once the option is engaged, which distorts all the stereo signals, with a more uneven sound reproduction first of all (and more centered on the mediums, with a rather unpleasant “acid” aspect) and also a part effect (delay/reverb) very short and confusing.
The behavior of the processing works a little better on content offered in 5.1, Dolby Atmos or 360 Reality Audio (both supported by the headphones): the scene gains in scale, and is indeed more enveloping from the point of view of the width. On the other hand, it is difficult to really feel the contribution of the elements supposed to be mixed at the back, which we particularly realize with the monitoring of head movements. What’s more, the location of the sources on the sides becomes quite imprecise. We are far from the real sound immersion promised.
