OnePlus Open Audio teszt

A OnePlus Opent szigorú SBMARK Audio tesztcsomagunkon keresztül vezettük be, hogy mérjük teljesítményét a beépített mikrofonokkal történő hangrögzítés és a hangszórókon keresztüli lejátszás során.
Ebben az áttekintésben lebontjuk, hogyan teljesített különféle tesztek során, és számos gyakori használati esetet.

Áttekintés

A legfontosabb hangspecifikációk a következők:

• Három hangszóró (bal felső, jobb felső, jobb alsó, nyitott állapotban)
• Nincs jack audio kimenet

Visszajátszás

Bejegyzés

With an overall score of 135, the OnePlus Open performed well in the SBMARK Audio tests. Thanks to an additional speaker, it is one of the very few foldable phones that offer stereo playback in portrait orientation when opened, making better use of its design and large size and providing better immersion than most competitors.

In our tests, the OnePlus performed consistently well in all use cases, thanks to a very pleasant timbre in both playback and recording. Our testers appreciated the device’s effective audio zoom feature, but also noted some flaws such as a lack of high-end extension, sometimes excessive dynamic processing, and compression in both playback and recording. According to measurements, neither the integrated speakers nor the microphones offer a full frequency range, which is unusual for a device of this class. However, that didn’t stop the OnePlus from delivering satisfying timbre and solid performance in our tests.

In playback, the OnePlus Open offered a pleasant timbre with a smooth tonal balance. The midrange was particularly warm and satisfying, but the lack of upper treble resulted in a certain dullness when listening to music. The bass sounded quite strong and round, but lacked extension in the low end. Dynamic performance was decent overall, but significantly hampered by high-volume compression. Attack seemed crisp and precise when listening to music or watching movies, but appeared slightly weak when gaming. Its performance was less satisfactory even at low and maximum volumes. As for bass performance, it offers good support, but the accuracy of the envelope was compromised by the compression, which also had a negative impact on the punch.

Thanks to a third speaker at the top left of the device, OnePlus Open is one of the rare and few foldables that offer stereo in vertical orientation as well as horizontal. However, the spatial performance still leaves some room for improvement. For starters, in our tests, the third speaker was very quiet, meaning that neither the balance nor the amplitude were actually good in portrait orientation, despite stereophony. The results in landscape orientation were also not particularly impressive. The stereo image wasn’t too wide, and while localizability was fine, it wasn’t always easy to locate individual sound sources. Distance performance was quite good, but voices could sound slightly further away than expected.

The distribution of volume levels was quite consistent and the maximum volume setting was quite high, but our experts found that the minimum volume level was extremely low and therefore difficult to use. Artifact performance was very good however, with only some compression evident at both nominal and maximum volumes, which was generally not problematic for the listening experience. Additionally, the device’s built-in speakers were virtually impossible to occlude.

Íme néhány hangnyomásszint (SPL), amelyet a hip-hop és klasszikus zene mintafelvételeinek maximális hangerőn történő lejátszásakor mértek:

A következő grafikon a hangerő fokozatos változásait mutatja a minimumról a maximumra. Elvárjuk, hogy ezek a változtatások következetesek legyenek az egész tartományban, hogy minden mennyiségnövekedés megfeleljen a felhasználói elvárásoknak:

When used as a recording device, OnePlus provided good tonal balance in all use cases. With the main and front cameras, the treble was correct but would have benefited from some additional high-end extension. It seemed clearer with the memo app. The midrange was satisfying and natural in all use cases, and while bass performance was good, it lacked low-end extension and depth. Thanks to a very effective noise reduction algorithm, the signal-to-noise ratio was good when recording with the main and front cameras. Attack was generally sharp and precise, but at high sound pressure levels, such as when recording loud concerts, the compression resulted in a lack of clarity.

The breadth of the sound stage and the localizability of individual sound sources proved to be very good when recording with the main camera. With the front camera the range was more limited, but the localizability remained good. Furthermore, distance rendering was realistic on all recording apps. Recording volume was adequate with the main and front cameras, but slightly weaker with the Memo app. Recordings made with the OnePlus were mostly free of artifacts, except for some compression at high sound pressure levels. Background rendering was also excellent and free of noticeable artifacts.
