On September 6, at the autumn launch of Huawei Mate50 series and new products with the theme of "meet at dawn", Huawei Mate50 series with HarmonyOS 3 was officially launched, and Huawei FreeBuds Pro 2 flagship headphones were unveiled again. Huawei FreeBuds Pro 2 audio experience was fully upgraded with Huawei Mate50 equipped with HarmonyOS 3, making us deeply aware of the endless surprises that true wireless headphones can show.

Multi-exclusive technology to create real 3D immersion as the industry's first TWS headset that supports Audio Vivid 3D sound standard, Huawei FreeBuds Pro 2 has realized end-to-end enhancement of HD space audio experience, higher definition content and more realistic sound. Coupled with Huawei's self-developed spatial audio rendering engine, Huawei FreeBuds Pro 2 implements three rendering modes: cinema, audio theater and concert hall, which can be manually adjusted according to different audio content, bringing different audio experience and always immersive listening experience with different rendering effects.

Behind the HD space audio of Huawei FreeBuds Pro 2, there is a very strong technical reserve. The first is the Audio Vivid audio codec standard, which is the first audio codec standard based on AI technology in the world. While ensuring the high quality of music, the audio channels and objects are processed through the AI method, and HarmonyOS 3 is perfectly adapted. Compared with the current schemes in the industry, Audio vivid compression efficiency (or coding efficiency) is higher, and it also supports HOA signal coding, which greatly enriches the expression of 3D audio content.

The second technology is the L2HC Bluetooth transmission protocol developed by Huawei, which achieves the highest 960kbps audio transmission bit rate, further avoids the sound quality damage in the audio transmission process, and ensures that the spatial audio content transmission is not discounted. The third is the support of Huawei's self-developed spatial audio rendering engine, which can match different music scenes and realize three rendering modes: cinema, audio theater and concert hall, which use different rendering strategies. Users can switch freely according to content and preference.

The fourth technique is dynamic head tracking. Huawei FreeBuds Pro 2 has a built-in gyroscope sensor, which can accurately grasp the subtle movement of the head, so that you can get a strong sense of telepresence when listening to music, watching a play or listening to audio books, just like listening to real music. The head moves and you can feel the sound varies according to your position or direction of rotation. This immersive listening experience has greatly enhanced the sound quality potential of Huawei FreeBuds Pro 2, so that every listening experience for users is the same as reality.

In order to give full play to the HD space audio strength of Huawei FreeBuds Pro 2, Huawei is also on-line exclusive content in streaming platforms such as Himalayas, Yunling, Huawei Music, Huawei video, etc., together with the dynamic head tracking function, you can feel the process that the sound changes according to its own position or rotation direction, so that every time you listen to the sound, you can "sound" in the scene.

In addition to technological breakthroughs, Huawei FreeBuds Pro 2 also brings a more simple manipulation experience. For example, users can choose different space audio modes as needed through Smart Life App; Huawei Mate 50 carries HarmonyOS 3 system, its super terminal interface also adds HD space audio user custom switch, which has head tracking, fixed, off, three modes and so on.

To achieve the original sound, listen to the new space audio function of "Zhi Zhen", Huawei FreeBuds Pro 2 has brought a new listening experience, while in the essence of headphones-sound quality, Huawei FreeBuds Pro 2 also has a good strength, won the praise of XDA, Tech Advisor and other international authoritative media, and recognized by Park Shu, Chen Shizhe, Yu Yang and other well-known related people. This is also due to the ultra-perceptual original sound dual-unit system adopted by Huawei FreeBuds Pro 2.

First of all, in terms of acoustic architecture, Huawei FreeBuds Pro 2 has made a breakthrough by adopting two independent sound units, high and low bass, and a digital frequency division scheme. The 11mm large moving coil unit uses a quadruple magnet double magnetic circuit system, which has a larger magnetic flux and a greater driving force for the diaphragm, which is 30% higher than that of the previous generation. In the design of the tweeter, Huawei FreeBuds Pro 2 uses a micro-flat tweeter used for high-end headphones, and its voice coil driving area accounts for a proportion of the total area of the diaphragm, which is 6 times higher than that of the previous generation of products. with the independent sound channel of the tweeter, you can hear the rich details of the rise and fall of the music.

Huawei FreeBuds Pro 2 also has digital dual frequency division technology, which uses built-in dual DAC to "split the music signal into two channels", bringing high frequency, medium and low frequency pure sound signals, moving coil unit and micro-flat tweeter unit do not interfere with each other, because of this, Huawei FreeBuds Pro 2 can perform well in low, medium and high frequencies, whether it is listening to dynamic DJ or classical concerts.

At the algorithm level, Huawei FreeBuds Pro 2 optimizes ear canal adaptation, wear adaptive compensation and volume adaptation to achieve triple real-time hearing optimization, so that the sound quality can be kept at its best under different users, different scenes and different volume. Huawei FreeBuds Pro 2 also has some "hard power", such as the use of LDAC and L2HC dual HD audio codec protocol, audio transmission rate of up to 990kbps, to achieve ultra-high-definition listening experience. At the same time, it has also obtained HWA and Hi-Res double gold standard certification in terms of acoustic performance, which is equivalent to laying the foundation for the sound quality strength of Huawei FreeBuds Pro 2.

In order to achieve the top sound quality, Huawei FreeBuds Pro 2 is tuned in conjunction with Divare. As an old friend of Huawei, Divare, together with Huawei, has carefully tuned the innovative acoustic design of Huawei FreeBuds Pro 2. For example, in the middle and low frequency tuning, they make the transition from the low frequency to the intermediate frequency more smooth, while keeping the elasticity and diving of the low frequency, they also ensure that the low frequency does not cover the fundamental frequency of the human voice, while in the intermediate frequency tuning, the reality and clarity of the human voice are further improved in the 4kHz~9kHz band, while the ultra-high frequency part takes into account the sense of hearing at the cutoff frequency point of the human ear, which is slightly suppressed. Overall, Jean Divare's joint tuning gives Huawei FreeBuds Pro 2 a surging bass, rich in detail and pure sound.

In terms of noise reduction, Huawei FreeBuds Pro 2 continues the excellent genes of the series and is equipped with a three-microphone active noise reduction system, which can achieve ultra-wideband noise reduction in the noise band of the main living environment of 50Hz-3kHz, with an average noise reduction of 15% higher than that of the previous generation, especially in a noisy environment, which can greatly reduce the conversation of people around them. In addition, the newly upgraded intelligent dynamic noise reduction 2.0 can also intelligently identify different scenes, and then match different noise reduction modes of balanced noise reduction, deep noise reduction and mild noise reduction. Huawei FreeBuds Pro 2 also optimizes aircraft noise reduction and designs its own aircraft noise reduction curve, which can be immersed in listening and undisturbed even on aircraft with roaring engines. In short, it is to make noise reduction understand you better.

With the new experience of full scene wisdom, HarmonyOS 3 makes the flagship accompanied by the release of the new Huawei Mate50 series, which is equipped with HarmonyOS 3 configuration, which not only enriches the "arsenal" of Huawei Mate50 series, but also enables Huawei FreeBuds Pro 2 to bring us a richer full scene wisdom experience.

For example, thanks to HarmonyOS's HyperTerminal feature, you can seamlessly stream audio from devices such as your phone / smart screen to your headset with a single click, and it also allows headphones to be connected to two devices at the same time. Without this feature, we would have to go through a tedious re-pairing process if we used other real wireless headphones to connect them to another device, which was quite inconvenient. At the same time, Huawei also introduced the "Audio connection Center" function in FreeBuds Pro 2, where you can see the 10 devices recently connected to your headphones. Select any nearby device and click to switch between multiple devices easily, which is very fast. You can also share beautiful audio with friends more easily, because HarmonyOS 3 supports two pairs of Huawei FreeBuds Pro 2 headphones connected to the same Huawei phone or Huawei Pad at the same time, making it extremely easy to listen to songs and follow dramas with friends.

In addition, there are features such as wisdom broadcast, quick reminder and morning greeting, which can make Huawei FreeBuds Pro 2 your intimate companion in the full scene intelligent life.

Written in the end: through a series of innovations in software and hardware, Huawei FreeBuds Pro 2 independently improves the sound quality of real wireless headphones, defines a new standard in the wireless audio era, and comprehensively leads the panoramic and intelligent experience of high-definition wireless audio.

With the release of the Huawei Mate 50 series, the above advantages will also be fully magnified. With a series of new features such as high-definition space audio technology, hyperterminal, audio sharing and so on, Huawei FreeBuds Pro 2 allows us to see the infinite possibilities of real wireless headphones in both sound quality and panoramic intelligent experience. Like Huawei's Mate phones, Huawei FreeBuds Pro 2's leading position in the audio field is unmatched. Huawei's brand event is about to reach its peak, and Huawei Mall has also offered full benefits. On September 15, Huawei FreeBuds Pro 2 new product limited time discount 100 yuan, Huawei FreeBuds 4e limited time discount 120 yuan.
