Shulou(Shulou.com)11/24 Report--

The rapid development of TWS true wireless headphones in recent years has opened up a blue sea in the mature industry of headphones, and then quickly became a red sea. Today's real wireless headphones have a lot of smart phone market, manufacturers are competing for each other, more and more volume. From appearance to connection, from noise reduction to sound quality, and then to spatial audio, the functions and experiences that can be thought of on headphones are almost drained by manufacturers.

However, it is a blessing for consumers, who can experience more comprehensive and comfortable TWS real wireless headphones at a more affordable price. On January 4th, another TWS real wireless headset product, which is very strong in all aspects, was released, which is the brand new one plus Buds Pro 2.

First, the design plus Buds Pro 2 package is still a classic red and white color matching, the square special board is positive, and the front is printed with the pattern of the headphone charging compartment and the body.

The headphones are available in accordion black and tree green, and the one CTOnews.com got is tree green. From the charging box to the headphone body is this kind of verdant and elegant green, looks very textured.

The round, raised surface of the charging box has the word "ONEPLUS" engraved on the paint surface, and the text "Dynaudio" at the bottom, which means that the sound quality of the headset is adjusted in cooperation with Dana.

Open the charging box and you can see the headphone body. The overall shape of one plus Buds Pro 2 is round and small, and the color matching of the whole Arbor green looks fresh and pleasant.

In the headphone rod part, the NCVM process is used to create a large area of metal texture, and the upper part of the headphone, including the earpiece, is painted with a matte surface to highlight the metal texture and the layering of the product. This design not only brings a high degree of recognition, but also an example of the combination of design and function, because the metal texture part is the pressure area, which can be easily manipulated through the difference of hand feel.

In terms of texture, the body of one plus Buds Pro 2 headphones also uses multiple spraying and hardened surface coating, which is not only close to skin and oil, but also takes into account the properties of scratch resistance, wear resistance and durability.

The headphone cavity part, one plus Buds Pro 2, is also designed based on ergonomics. When wearing, the headphone repeatedly polishes the pressure of the eardrum, earnail cavity, ear canal and other positions, so as to improve the comfort and stability of wearing headphones.

Moreover, the single ear weight of one plus Buds Pro 2 is only 4.9g, which is very light and will not feel uncomfortable even if you wear it for a long time.

In addition, in the package, one plus also comes with earplugs of different sizes, charging wires, instructions and so on.

Generally speaking, the appearance of one plus Buds Pro 2 headphones still maintains a high degree of recognition and industrial design. Arbor Green's unique and elegant color matching is an addition. Wearing it on most occasions can add a bit of fashion to you.

Second, full-link space audio TWS true wireless headphones after rolling up sound quality and noise reduction, the next important function is space audio. This is one of the key innovations of OnePlus Buds Pro 2.

Specifically, this time, one plus Buds Pro 2 has launched a set of full-link space audio functions, from system architecture to rendering algorithms, to headset optimization, resource expansion, and so on. They have opened up the upstream and downstream of spatial audio, which is the first time in Android ecology.

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 code stream to the device layer, and could not natively achieve multi-channel transmission, so third-party App or equipment vendors wanted to achieve spatial audio, they could only build spatial audio ecology in a "plug-in" way, so it was easy to have compatibility problems with each other, and the effect was difficult to be guaranteed.

This time, Yiga has reconstructed the underlying audio framework of Android 13 to achieve native support for spatial audio. In this way, you can directly enjoy the immersive and three-dimensional sound field by using headphones that support space audio, resulting in better stability and compatibility.

On this basis, Yiga also added a self-developed up-mixing algorithm, so that stereo can also simulate the effect of space audio, and they also made in-depth optimization of space audio rendering algorithm, including scene customization algorithm and the latest head-to-head algorithm. To achieve the best experience of space audio.

Then, on the headset, one plus Buds Pro 2 embeds a high-precision six-axis IMU sensor, so that the headset can accurately simulate the relative rotation between the sound space and the head, so that the user can feel immersive, and the minimum delay is about 150ms.

Finally, there is the content side. At present, OPPO music has been put on the shelves 3000 first time to produce space audio music, and they have reached cooperation with iqiyi and other domestic TOP applications to further complete space audio resources.

When using the test, CTOnews.com paired the one plus 11 phone with one plus Buds Pro 2 to turn on head tracking mode.

There is a special spatial audio area in "OPPO Music", in which there are a large number of songs that support spatial audio. CTOnews.com has listened to many of them, and almost every song can have a good spatial audio effect.

For example, in this song "lost", you will feel that the atmosphere created by Beth comes from this area in front of you, while other guitars and other accompaniment are directly in front of you, and the voice seems to be right in front of you. When you turn your head to the left, the singer seems to be singing against your right ear, and when you turn your head to the right, it is as if you are singing in your left ear. In short, it seems that the human voice is in that fixed position in front of your eyes, and it feels wonderful and immersive.

In addition to "OPPO Music", the stereo songs in the third-party App can also hear the effect of spatial audio using one plus Buds Pro 2. For example, "NetYun Music", when you turn on Dolby panoramic sound effect, randomly find a song that supports panoramic sound, and you can also experience the effect of spatial audio. Even ordinary songs have obvious spatial audio head tracking effect.

The same is true with the "QQ Music" test. For example, CTOnews.com uses QQ Music's "Zhenpin panoramic sound" to listen to "California Hotel". With the blessing of space audio, the applause, cheers, guitar and drumbeat of the scene seem to be happening around him, especially if there is no sand hammer, it is wonderful to shake it in the right ear all the time.

In addition to music, wearing a Buds Pro 2 to watch movies and chase shows with video App, you can also get the effect of spatial audio. For example, when the editor uses Dolby panoramic sound effect to watch the Avengers on iqiyi, all kinds of detached fighting sounds seem to be in his ear, and explosions from different directions can be distinguished.

Compared with music, one plus Buds Pro 2 puts more emphasis on bringing a wide sound field, a strong sense of atmosphere and a strong human voice when facing a video scene, as if it were watched in a cinema. CTOnews.com tested some Dolby panoramic sound blockbusters and some ordinary domestic cinema movies, all of which can create an immersive feeling through spatial audio effects.

In short, one plus Buds Pro 2 full link space audio perception is still very strong, not only the sound sense of space, direction effect is more immersed, more stable, and do not have to worry about space audio resources, whether multi-channel or stereo, can enjoy the space audio experience, space audio completed the "conventional weapon".

Sound quality experience with the development and evolution of TWS true wireless headphones in connection technology, their sound quality performance has been able to compete with many wired headphones. One plus Buds Pro 2 is one of them.

This headset has partnered with Dynaudio, a famous Nordic audio brand, to jointly develop the industry's leading coaxial double-coil unit acoustic system, which is derived from the high-end audio design concept of low-and low-pitched double-unit frequency division, including 11mm subwoofer and 6mm high-sensing tweeter unit, the two units are arranged in coaxial form, so that the perfect integration of frequency division points, can present a rich and delicate sound quality.

In terms of transmission performance, one plus Buds Pro 2 with one plus mobile phone 11 series can achieve Hi-Res high-resolution transmission, acoustic performance can achieve Hi-Res Wireless gold standard certification, the new LHDC 5.0technology can also greatly improve the sound quality transmission bit rate (need to wait for subsequent OTA upgrades). At the same time, the adaptive range of 128kbps-1000kpbs can better ensure the balance of sound quality and stability in a complex environment, making people feel the sound quality experience of Hi-Fi level at any time.

In terms of the actual sound quality experience, CTOnews.com is still explained by the listening experience of several classic songs. The first is Cai Qin's "Ferry," a prelude to the song with a low drumbeat, a strong and powerful restoration of the bass with Buds Pro 2, not the kind of soft dive, which sounds shocking, which is more than expected for a wireless headset.

Then the crisp guitar sound sounded, with Cai Qin's warm and delicate voice, one plus Buds Pro 2 made a pleasant and exquisite expression of both, the human voice is very sweet, and the sense of hierarchy is enough. It can be seen that the performance of Buds Pro 2 in both low-frequency and intermediate-frequency sound is quite powerful.

Meav's "ONE I LOVE" lip and tooth sounds and breath sounds are more obvious, mainly listening to resolution. One plus Buds Pro 2 on the front of the breath sound, lip sound restore are very clear, delicate. And some of the high notes in the middle of the song, plus Buds Pro 2, are also full and penetrating.

In terms of sound quality, Buds Pro 2 also introduces the golden hearing function, which is developed by Yijia Acoustics Lab, which integrates the structure of the user's ear canal, hearing characteristics, psychoacoustics, headphone acoustic system and other dimensions for analysis and modeling, showing accurate and delicate sound and enriching the detailed performance of the sound, so that each user can hear the pure original sound, and in a variety of scenes and motion states. Can have a delicate and consistent listening experience.

In the actual experience, if you turn on the golden listening function after debugging, you will feel that you can hear more layers of music, fuller in high frequency, and more sound details can be heard in low frequency than when you don't open it. Therefore, it is suggested that before you really use it, you should first do some debugging of the sound of gold.

4. Noise reduction experience TWS true wireless headphones are suitable for use in many scenarios because of their portability, so the ability of noise reduction is very important. How is the noise reduction performance of one plus Buds Pro 2?

In terms of parameter configuration, one plus Buds Pro 2 is equipped with a three-core noise reduction chip and four noise reduction microphones to achieve dual active noise reduction. The deepest noise reduction can reach 48dB, which is 20% higher than that of the previous generation, and the effective noise reduction bandwidth reaches 4KHz, which is double that of the previous generation.

In this way, one plus Buds Pro 2 can effectively reduce the noise of the human voice band which is difficult to be handled by traditional noise reduction headphones, so that users can get a clearer and more immersive listening experience in the complex background sound, especially in the human voice environment.

During the test, CTOnews.com chose to conduct a listening test in shopping malls with a relatively dense flow of people, and first turned on the moderate noise reduction mode that one plus Buds Pro 2 was most suitable for shopping malls, when the normal voice of the people around them could no longer be heard, and they saw the mouth of the people around them moving. The music in the headphones is immersed, but occasionally a child's loud screams can be heard.

When we arrived in the square in front of the mall gate, the editor turned on the deep noise reduction mode, and the sound of cars passing by on the road not far away could not be heard, and the world seemed to be much quieter, but the sound of traffic horns could still be heard.

Of course, every day on the road, for safety reasons, people still have to use the one plus Buds Pro 2 penetration mode, which does not hinder listening to music, but also can hear cars driving around, sirens and some people talking.

The noise reduction function of headphones also has an important application scenario, that is, call noise reduction. One plus Buds Pro 2 uses a three-microphone noise reduction scheme, with three high-sensitivity microphones built into each headset. Among them, two microphones outside the ear are "beamforming" to accurately recognize the voice (human voice), avoid the interference of the surrounding noise, and only recognize your voice. A microphone in the ear can pick up the pure voice transmitted by the inner ear canal, effectively weaken the call noise and make the other party hear more clearly.

CTOnews.com also tested the call noise reduction ability of one plus Buds Pro 2. During the test, the editor used sound around both sides of the call to simulate the noise of busy traffic, and the noise volume tried to simulate the effect that we could hear during the rush hour. Then use the call recording function to record the call:

During the above call, the female voice who began to read the article used one plus Buds Pro 2, the voice was very clear, and the background noise could only hear sporadic high-pitched car sirens, not to mention the harsh noise. in fact, when she spoke, the simulated traffic noise around her was still noisy. The editor was also very smooth in the process of talking to her, heard very clearly, and was not interrupted by the noise.

In addition, one plus Buds Pro 2 also supports personalized noise reduction, which intelligently optimizes the noise reduction curve and corrects the noise reduction deviation according to the structure of the user's ear canal. In order to achieve the function of the best noise reduction effect for specific users, and achieve the personalized noise reduction of ear measurement customization.

Then there is intelligent dynamic noise reduction, which can identify the sound features in the environment. You do not have to switch noise reduction levels repeatedly, and the algorithm automatically matches the best noise reduction level. These functions can make your noise reduction experience more intelligent, more convenient and comfortable.

Other user experience for a TWS true wireless headset, in addition to the main functions such as sound quality, tuning and noise reduction, other daily use and interactive experience will also affect users' feelings. Does one plus 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. One plus Buds Pro 2 supports Bluetooth 5.3 low delay dual transmission technology, and the full link delay can be as low as 54ms. The editor wore one plus Buds Pro 2 to play a game of "Game for Peace" and found that there was no delay in the sound transmission of headphones. When you press the shooting button, there will be gunshots, and when there are enemies around you, you will immediately hear footsteps, and with the blessing of spatial audio, you will listen to the sound and identify the position at the first time, which is very accurate.

One plus Buds Pro 2 also supports the dual connection function of the device, which can switch freely between the two devices without disconnecting the reconnection.

When two devices are connected, when one device calls or plays media, the headset is automatically connected to that device, and when the other device plays sound, the headset automatically switches to this device. There is almost no delay in the switching process, which is almost seamless, as can be seen from the demonstration of CTOnews.com below.

In the aspect of manipulation, the metal smooth lacquer part of the headphone handle is the control area, which is obviously different from the matte touch of the cavity part, so it can be operated blindly. Here, you can press a single pinch, two pinch, three pinch, long press to achieve playback / pause, switching songs, noise reduction / penetration and other functions, and each pinching operation can distinguish between the left and right ears to achieve different functions, as long as you can skillfully remember The interaction will be very convenient.

In addition, one plus Buds Pro 2 also supports a unique feature, which is focus mode. As long as you press the headphone handle for 3 seconds, you can automatically play white noise, help you relieve stress, or help you focus on your study or work, use it at night, and help users sleep.

Finally, the battery life, one plus Buds Pro 2 with headphone charging box can achieve up to 39 hours of battery life, to the editor to test the use intensity of this period of time, intermittent use of about 2-3 hours a day, used for more than a week, has not yet been charged. On the whole, the endurance of it can make the editor satisfied.

In addition, the headset also supports fast charging function, charging 10 minutes, you can get the headset + charging box about 7 hours of music life, not to mention worry about battery life. The editor is used to listening to audio books on his way from work every day, so he usually charges them temporarily for a while before getting off work, and has never encountered a situation where half of them have no electricity.

Conclusion at a time when the competition in the TWS true wireless headset market is becoming more and more fierce, product-level innovation will become more and more difficult, and this innovation in spatial audio full link access with Buds Pro 2 is believed to be the result of a long-term and in-depth survey of user experience.

In addition, one plus Buds Pro 2 also has a good performance in appearance, sound quality, noise reduction, interaction, delay, battery life and so on. It can be said that it is another "polygon warrior" in the real wireless headphone market.

If you want to upgrade your headphone equipment in 2023, then one plus Buds Pro 2 is undoubtedly one of the options worth considering, especially if you are using an one plus phone, it is more recommended to buy this one plus Buds Pro 2.
