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.

Kif huwa magħmul il-punteġġ tal-plejbek tal-awdjo
L-inġiniera ta’ SBMARK jittestjaw id-daqq permezz ta’ kelliema tal-ismartphone, li l-prestazzjoni tagħhom tiġi evalwata fil-laboratorji tagħna u f’kundizzjonijiet tal-ħajja reali, bl-użu ta’ apps u settings awtomatiċi.
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.

Hawn kif l-OnePlus Open jaħdem f'każijiet ta 'użu ta' daqq meta mqabbel mal-kompetituri tiegħu:
Logħba ta' punteġġi ta' każi ta' użu
Il-punteġġ tat-Timbre jirrappreżenta l-kwalità li biha telefon jirriproduċi l-ħoss tul il-firxa tonali kollha li tinstema' u jqis id-dipendenza tal-bass, midrange, treble, tal-bilanċ tonali u tal-volum. Huwa l-aktar attribut importanti għar-riproduzzjoni.

Il-punteġġ Dynamics ikejjel l-eżattezza tal-bidliet fil-livell tal-enerġija tas-sorsi tal-ħoss, bħal kemm tiġi riprodotta b'mod preċiż nota tal-baxx jew il-ħoss ta 'impatt ta' drum.
Attributi sekondarji ta 'testijiet spazjali jinkludu l-identifikazzjoni tal-post ta' ħoss speċifiku, il-bilanċ pożizzjonali tiegħu, id-distanza u l-amplitudni.
Il-punteġġ tal-volum jirrappreżenta l-volum ġenerali ta 'smartphone u kemm il-volum jiżdied u jonqos bla xkiel abbażi tal-input tal-utent.
Hawn huma xi livelli ta' pressjoni tal-ħoss (SPLs) imkejla meta nilqgħu r-reġistrazzjonijiet kampjuni tagħna ta' hip-hop u mużika klassika fil-volum massimu:
| hip hop | Classic | |
| OnePlus miftuħ | 75 dBA | 73.5 dBA |
| Samsung Galaxy Z Fold5 | 72.8 dBA | 69.4 dBA |
| Apple iPhone 15 Pro Max | 75.1 dBA | 72.3 dBA |
Il-graff li ġej turi l-bidliet gradwali fil-volum li jmorru minn minimu għal massimu. Nistennew li dawn il-bidliet ikunu konsistenti fil-firxa kollha, sabiex iż-żidiet kollha fil-volum jaqblu mal-aspettattivi tal-utenti:
Konsistenza tal-volum tal-mużika
Din il-grafika tal-linja turi l-volum relattiv ta 'daqq kontra l-inkrement tal-volum magħżul mill-utent, imkejjel f'żidiet ta' volum differenti b'ħoss roża korrelatat f'kaxxa anekoika rreġistrata fuq l-assi f'0.20 metri.
Il-punteġġ Artifacts ikejjel il-punt sa fejn il-ħoss huwa affettwat minn diversi tipi ta 'distorsjoni. Aktar ma jkun għoli l-punteġġ, inqas ikun notevoli d-disturbi tal-ħoss. Jistgħu jseħħu distorsjonijiet minħabba l-ipproċessar tal-ħoss fl-apparat u l-kwalità tal-kelliema.

Kif huwa magħmul il-punteġġ tar-reġistrazzjoni tal-awdjo
L-inġiniera ta 'SBMARK jittestjaw ir-reġistrazzjoni billi jevalwaw fajls irreġistrati fuq tagħmir awdjo ta' referenza. Dawn ir-reġistrazzjonijiet isiru fil-laboratorji tagħna u f'kundizzjonijiet tal-ħajja reali, bl-użu ta 'apps u settings default.
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.

Il-punteġġ iqis ukoll il-proporzjon tas-sinjal għall-istorbju (SNR), bħal kemm il-vuċi prinċipali hija qawwija meta mqabbla mal-istorbju fl-isfond.
Attributi sekondarji għall-ittestjar spazjali jinkludu l-identifikazzjoni tal-post ta 'ħoss speċifiku, il-bilanċ pożizzjonali tiegħu, id-distanza, u l-amplitudni fuq fajls awdjo rreġistrati.
Direttiva ta' reġistrazzjoni
Grafika tad-direttività tal-ismartphone waqt ir-reġistrazzjoni tas-sinjali tat-test bl-użu tal-app tal-kamera, bil-kamera prinċipali. Jirrappreżenta l-enerġija akustika (f'dB) meta mqabbla mal-angolu tal-inċidenza tas-sors tal-ħoss. (Normalizzat għall-angolu ta '0 °, quddiem l-apparat.)
Il-punteġġ tal-loudness jirrappreżenta kemm l-awdjo fuq il-fajls irreġistrati huwa normalizzat u kemm l-apparat jimmaniġġa tajjeb ambjenti storbjużi, bħal kunċerti elettroniċi, waqt ir-reġistrazzjoni.
Hawn huma l-livelli tal-ħoss irreġistrati fil-fajls tal-awdjo u tal-vidjo, imkejla f'LUFS (Loudness Unit Full Scale); Bħala referenza, nistennew li l-livelli tal-volum ikunu ogħla minn -24 LUFS għall-kontenut irreġistrat:
| Laqgħa | Vidjows dwar il-ħajja | Selfie videos | Memorandum | |
| OnePlus miftuħ | -26.8 LUFS | -21 LUFS | -19.2 LUFS | -19.1 LUFS |
| Samsung Galaxy Z Fold5 | -25.8 LUFS | -22.1 LUFS | -21 LUFS | -21.1 LUFS |
| Apple iPhone 15 Pro Max | -24.9 LUFS | -22.1 LUFS | -20.5 LUFS | -19.2 LUFS |
Il-punteġġ Artifacts ikejjel sa liema punt il-ħsejjes irreġistrati huma affettwati minn diversi tipi ta 'distorsjonijiet. Aktar ma jkun għoli l-punteġġ, inqas ikun notevoli d-disturbi tal-ħoss. Jistgħu jseħħu distorsjonijiet minħabba l-ipproċessar tal-ħoss fl-apparat u l-kwalità tal-mikrofoni, kif ukoll l-immaniġġjar tal-utent, bħal kif jinżamm it-telefon.
