OnePlus Buds Pro 2 Review: A Budget Set of True Wireless ANC Earbuds


It is a blessing for consumers that nowadays everyone can experience more comprehensive and comfortable TWS true wireless earphones at a more affordable price. And just on January 4, another TWS true wireless headset that is very powerful in all aspects was released, that is the brand new OnePlus Buds Pro 2. And today we will review it.

Unboxing and Design

The packaging of the Buds Pro 2 is still the classic red and white color scheme of the OnePlus.


This headset has two colors obsidian black and arbor green, and the one that we got is arbor green. From the charging box to the body of the earphone is this elegant green, which looks very textured.


The round and raised surface of the charging box has the words “ONEPLUS” engraved on the lacquer surface, and the words “Dynaudio” below, which means that the sound quality of this headset is adjusted in cooperation with Dynaudio.



Open the charging box, you can see the earphone body. The overall shape of the OnePlus Buds Pro 2 is round and compact, and the whole body arbor green color looks fresh and pleasant.


For the headphone rod part, OnePlus uses NCVM technology to create a large area of ​​metal texture, and the upper part of the earphone, including the ear, is sprayed with a matte surface to highlight the metal texture and the layering of the product. This design not only brings high recognition but also a model of the combination of design and function because the metal texture part is a pressure-sensitive area, which can be easily controlled by the difference in hand feel.


In terms of texture, the OnePlus Buds Pro 2 headphone body also uses multiple sprays and a hardened surface coating, which is not only skin-friendly and oil-repellent but also scratch-resistant, wear-resistant, and durable.


For the headphone cavity, OnePlus Buds Pro 2 is also designed based on ergonomics. When wearing the earphones, the pressure sensitivity of the tragus, concha cavity, and ear canal has been repeatedly polished to improve the comfort and stability of wearing the earphones. sex.


Moreover, the weight of one ear of the OnePlus Buds Pro 2 is only 4.9g, which is very light and will not feel uncomfortable when worn for a long time. In addition, in the package, OnePlus also comes with earplugs of different sizes, as well as charging cables, manuals, etc.


Overall, the appearance of the OnePlus Buds Pro 2 earphones still maintains a high level of recognition and industrial design. The unique and elegant color scheme of arbor green is a bonus item. Wearing it on most occasions can be seen for you. Add a bit of fashion temperament.

Full link spatial audio

After the sound quality and noise reduction of TWS true wireless earphones, the next important function is spatial audio. This is one of the key innovations of the OnePlus Buds Pro 2.

Specifically, this time OnePlus Buds Pro 2 launched a set of full-link spatial audio functions, from system architecture to rendering algorithms, to earphone optimization, resource expansion, etc., they opened up the upstream and downstream of the spatial audio, which is the first time in the Android ecosystem,


The so-called full link is compared with the past. In the past, the Android audio framework was very simple. It could only output 2.0 stereo streams to the device layer, and could not realize multi-channel transmission natively. Therefore, third-party apps or device manufacturers who want to realize spatial audio can only build spaces in the way of “plug-in” Audio ecology, so it is easy to have compatibility problems with each other, and the effect is difficult to guarantee.


And this time, OnePlus refactored the underlying audio framework of Android 13 to realize native support for spatial audio. In this way, you can directly enjoy an immersive and three-dimensional sound field with headphones that support spatial audio, and the stability and compatibility are better.


On this basis, OnePlus also added a self-developed upmixing algorithm, so that stereo can also simulate the effect of spatial audio. At the same time, they also deeply optimized the rendering algorithm of the spatial audio, including scene-specific custom algorithms and the latest head-turning Algorithm to achieve the best experience of spatial audio.

Then on the headset, OnePlus Buds Pro 2 is embedded with a high-precision six-axis IMU sensor, so that the headset can accurately simulate the relative rotational movement of the sound space and the head, allowing users to feel the immersive sense of immersion with the lowest delay Also reached about 150ms.


Finally, on the content side, OPPO Music has put 3,000 remade spatial audio music on the shelves, and they have reached cooperation with domestic TOP applications such as iQiyi to further complement the spatial audio resources.

When using the test, we used the OnePlus 11 smartphone released this time to pair with OnePlus Buds Pro 2, and turned on the head tracking mode.


There is a special space audio area in “OPPO Music”, which contains a large number of songs that support spatial audio. We have listened to many of them, and almost every song can have a good spatial audio effect.


For example, in this song “Trek”, you will feel that the atmosphere created by the bass is transmitted from the area in front of you, while other accompaniments such as guitars are directly in front, and the vocals seem to be right in front of you. When you turn your head to the left, the singer seems to be singing next to your right ear, and when you turn your head to the right, it seems to be singing next to your left ear. In short, it seems that the human voice is in a fixed position in front of you, which feels amazing, Very immersive.


In addition to “OPPO Music”, stereo songs in third-party apps can also hear the effect of spatial audio using OnePlus Buds Pro 2. For example, in “NetEase Cloud Music”, when you turn on the Dolby Atmos sound effect and find a song that supports Atmos, you can also experience the effect of spatial audio. Even ordinary songs will have obvious spatial audio head-tracking effects.


The same is true for testing with “QQ Music”. For example, we listened to “California Hotel” with QQ Music’s “Zhenpin Panorama”. Ruo Wu’s maraca swayed gently beside his right ear, feeling very wonderful.


In addition to music, wearing OnePlus Buds Pro 2 and watching movies and dramas with video apps can also get the effect of spatial audio. For example, the editor used Dolby panoramic sound effects to watch “The Avengers” on “Iqiyi”. All kinds of transcendent fighting sounds seemed to be in my ears, and the sounds of explosions from different directions could also be distinguished.


Compared with music, OnePlus Buds Pro 2 is more focused on bringing a wide sound field, a strong sense of atmosphere, and a rich human voice when facing video scenes, as if watching it in a movie theater. We have tested some Dolby Atmos blockbusters and some ordinary domestic theater movies, and they can all create an immersive feeling through spatial audio sound effects.

In short, OnePlus Buds Pro 2 full-link spatial audio perception is still very strong. Not only is the spatial and directional effects of the sound more immersive and stable, but also there is no need to worry about spatial audio resources, whether it is multi-channel or stereo, you can enjoy the spatial audio experience, which can be regarded as a “conventional weapon” for spatial audio.

Sound quality experience

With the development and evolution of TWS true wireless earphones in terms of connection technology, their sound quality performance can already compete with many wired earphones. OnePlus Buds Pro 2 is one of them.

This headset has cooperated with the famous Nordic audio brand Dynaudio to jointly develop the industry-leading coaxial dual dynamic unit acoustic system, which is derived from the high-low frequency dual-unit frequency division design concept of high-end audio, including 11mm super elastic woofer And 6mm high-sensing tweeter, the two units are arranged in a coaxial form, so that the frequency crossover point is perfectly integrated, and it can present rich and delicate sound quality.


In terms of transmission performance, OnePlus Buds Pro 2 paired with OnePlus mobile phone 11 series can achieve Hi-Res high-resolution transmission, and the acoustic performance has reached Hi-Res Wireless Gold Standard certification. The new LHDC 5.0 technology can also greatly improve the sound quality transmission bit rate ( Need to wait for the subsequent OTA upgrade). At the same time, the adaptive range of 128kbps-1000kpbs can better ensure the balance of sound quality and stability in complex environments, allowing people to experience Hi-Fi-level sound quality experience at any time.


As far as the actual sound quality experience is concerned, we still use the listening experience of several classic songs to illustrate. The first is Cai Qin’s “Ferry Crossing”. There is a low drum sound in the prelude of this song. OnePlus Buds Pro 2 restores the bass powerfully, not the kind of soft dive. It sounds full of shock. For a wireless earphone That being said, it exceeded expectations.


Then the crisp guitar sounds, matched with Cai Qin’s warm and delicate vocals, OnePlus Buds Pro 2 has made a pleasant and delicate expression of both, the vocals are very sweet, and the layering is enough. It can be seen that the performance of the OnePlus Buds Pro 2 in low-frequency and mid-frequency sound is relatively good.

Meav’s “ONE I LOVE” has more obvious labial-tooth and breath sounds, mainly due to aural resolution. OnePlus Buds Pro 2 is very clear and delicate for the front breathing sound and lip sound restoration. As for some high notes in the middle part of the song, OnePlus Buds Pro 2 is also full and penetrating.


In terms of sound quality, OnePlus Buds Pro 2 also introduces a golden sense of hearing function, which is self-developed by OnePlus Acoustics Laboratory. mode, presenting accurate and delicate sound and enriching the details of the sound, so that every user can hear the pure original sound, and can have a delicate and consistent listening experience in various scenes and sports states.


In the actual experience, if you turn on the golden hearing function after debugging, you will feel that the music you hear has a richer sense of hierarchy, the high frequency is fuller, and the sound details that can be heard in the low frequency are more than when it is not turned on. Therefore, it is recommended that you do some debugging of the golden sense of hearing before actually using it.

Noise reduction function experience

Due to its portability, TWS true wireless earphones are suitable for use in many scenarios, so the noise reduction capability is very important. How about the noise reduction performance of the OnePlus Buds Pro 2?

From the perspective of parameter configuration, OnePlus Buds Pro 2 is equipped with a triple-core noise reduction chip and has 4 noise reduction microphones to achieve dual active noise reduction. The deepest noise reduction can reach 48dB, which is 20% higher than the previous generation, effectively The noise reduction bandwidth reaches 4KHz, which is double that of the previous generation.


In this way, OnePlus Buds Pro 2 can effectively reduce the noise of the vocal frequency band that is difficult for traditional noise-canceling headphones, allowing users to obtain a clearer and more immersive listening experience in complex background sounds, especially in the human voice environment.

During the test, we chose to conduct a listening test in a shopping mall with a relatively dense flow of people. First, turn on the moderate noise reduction mode of the OnePlus Buds Pro 2, which is most suitable for shopping malls. See the mouths of people around you move. The music in the earphones is very immersive, but occasionally the loud screams of children can still be heard.


When I arrived at the square in front of the mall gate, the editor turned on the deep noise reduction mode. At this time, the whirring of cars passing by on the road not far away could not be heard. The world seemed to be much quieter, but the sound of vehicles honking was still Can hear.

Of course, on the road every day, for the sake of safety, you still have to use the transparent mode of the OnePlus Buds Pro 2, which will not hinder listening to songs, and you can also hear the sound of cars driving, horns and some people talking around you.


Another important application scenario for the noise reduction function of headphones is called noise reduction. OnePlus Buds Pro 2 uses a three-microphone noise reduction solution, and each earphone has three built-in high-sensitivity microphones. Among them, the two microphones outside the ear “beamforming” can accurately recognize voice (human voice), avoid the interference of surrounding noise, and only recognize your voice. A microphone in the ear can pick up the pure voice conducted by the inner ear canal, effectively weaken the noise of the call, and let the other party hear more clearly.


We also tested the call noise reduction ability of the OnePlus Buds Pro 2. During the test, the editor used speakers around both sides of the call to simulate the noise of busy traffic. The noise volume tried to simulate the effect that we can hear during the peak hours of our daily commute. Then use the call recording function to record the call process:

During the above call, the female voice who started to read the article was using OnePlus Buds Pro 2. The human voice is very clear, and the background noise can only hear sporadic high-pitched car horns, and there is no harsh noise. In fact, she is talking, and the simulated traffic noise around is still quite noisy. The editor’s conversation with her was also very smooth, and she could hear clearly without being interrupted by the loud noise.

In addition, OnePlus Buds Pro 2 also supports a personalized noise reduction function, which is also to intelligently optimizes the noise reduction curve according to the structure of the user’s ear canal and corrects the noise reduction deviation. In order to realize the function of the best noise reduction effect for specific users, it can achieve personalized noise reduction customized by ear measurement.


Then there is intelligent dynamic noise reduction, which can recognize the sound characteristics in the environment. You don’t have to switch the noise reduction level repeatedly, and the algorithm automatically matches the best noise reduction level. These functions can make your noise reduction experience smarter, more convenient, and more comfortable.

Other experience

For a TWS true wireless headset, in addition to the main functions of sound quality, tuning, and noise reduction, other daily use, and interactive experiences will also greatly affect the user experience. Does OnePlus Buds Pro 2 take care of these details?

The first thing to say is the sound delay, especially when playing games with Bluetooth headsets, the delay is unacceptable. OnePlus Buds Pro 2 supports Bluetooth 5.3 low-latency dual-pass technology, and the full-link delay can be as low as 54ms.


The editor wore OnePlus Buds Pro 2 to play a game of “PUBG Elite”, and found that the sound transmission of the earphones did not feel delayed. Press the fire button and there will be gunshots. When there are enemies around, you will also hear footsteps immediately. , and with the blessing of the spatial audio, it is very accurate to listen to the sound and identify the position at the first time.

OnePlus Buds Pro 2 also supports the device’s dual connection function, which can switch freely between the two devices without disconnecting and reconnecting.


When two devices are connected, when one device receives a call or plays media, the headset will automatically connect to this device, and when the other device plays sound, the headset will automatically switch to this device. There is almost no delay in the switching process, which is equivalent to seamless, as can be seen from the demo below.

In terms of control, the metal smooth vermilion lacquer part of the earphone handle is the control area, which is obviously different from the matte touch of the cavity part, which can be easily operated blindly. Here you can perform single, double, triple, and long presses To achieve play/pause, switch songs, noise reduction/transparency, and other functions, and each pinch operation can also distinguish the left and right ears to achieve different functions. As long as you can memorize it proficiently, the interaction will be very convenient.


In addition, OnePlus Buds Pro 2 also supports a unique feature, which is the focus mode. Just press and hold the earphone handle for 3 seconds, it can automatically play white noise to help you relieve stress, or help you focus on studying or working. It can also help users fall asleep when used at night.


The last is the battery life. OnePlus Buds Pro 2 with the earphone charging box can achieve up to 39 hours of battery life. According to the intensity of use during the test period of the editor, the intermittent use is about 2-3 hours a day. It hasn’t been charged for weeks. Overall, its battery life can still satisfy the editor.


Moreover, this headset also supports the fast charging function. After charging for 10 minutes, you can get about 7 hours of music life from the headset + charging box, so you don’t have to worry about battery life. The editor is used to listening to audiobooks on the way home from get off work every day, so I usually charge it for a short time before leaving get off work, and I have never encountered a situation where the battery is half used.


As the competition in the TWS true wireless headset market becomes more and more fierce, innovation at the product level will become increasingly difficult. This time, the innovation of the OnePlus Buds Pro 2 in opening up the full link of spatial audio is believed to be a long-term in-depth study of the user experience. The results of the investigation.


In addition, OnePlus Buds Pro 2 also has good performance in terms of appearance, sound quality, noise reduction, interaction, delay, and battery life. It can be said to be another “polygon warrior” in the true wireless headset market.

If you want to upgrade your headphone equipment in 2023, then OnePlus Buds Pro 2 is undoubtedly one of the options worth considering, especially if you are using a OnePlus mobile phone, it is recommended that you start with this OnePlus Buds Pro 2 up.
