Huawei FreeBuds Pro 3 opens a new era of TWS lossless listening

On November 23, Huawei held a media communication meeting on audio innovation technology at the Opera Concert Hall of the Central Conservatory of Music. "Listening to the original sound" is the focus of this concert. Guests not only listened to the wonderful performances of musicians on the spot, but also listened to the first movement of Vivaldi's Winter with Huawei FreeBuds Pro 3 at Huawei's invitation after the concert. Through the interpretation of Huawei FreeBuds Pro 3, the unique music atmosphere of the first movement of Winter has been perfectly reproduced again.

Today, the way people listen to music has changed, thanks to the development of music streaming media and the popularity of true wireless headphones. Enjoying music has become extremely simple and natural, which can be described as a typical example of technology changing life. It can also be seen from the market performance that the real wireless headset has always demonstrated its unique market vitality, and various manufacturers are competing for innovation ability in this field. However, the competition of today's real wireless headset products is very fierce, but both new brands and old manufacturers have to face the fact that the real wireless headset has entered the stock market, and each is competing for a breakthrough in technological innovation. Among them, with the increasing demand of consumers for the sound quality of earphones, auditory experience has become the focus of competition. In this "arms race" of sound quality, lossless audio is an important development direction of true wireless headphones. Lossless audio not only means higher data transmission rate and better sound quality, it also represents the respect for the essence of music and the pursuit of details.

But the real wireless earphones on the market have been struggling to achieve true lossless sound quality. It requires not only high standard hardware support, but also Software The support of in-depth optimization and innovative algorithms. Huawei FreeBuds Pro3 is a bold innovation of Huawei in the audio field. It is also the only true wireless headset in the market that has achieved CD level lossless audio quality transmission. It has successfully overcome many technical obstacles in the process of lossless transmission, and has brought users an auditory feast beyond expectations.

Challenge Lossless Audio

In order to pursue lossless audio quality, many audio enthusiasts often need to use wired headphones to ensure the stable transmission of audio signals, and also need a complex HiFi decoding system. Although the real wireless headset is very convenient in use, it needs to face more challenges to achieve lossless audio transmission. First of all, the instability of wireless transmission itself may lead to data loss, which is crucial to ensure sound quality. Secondly, the miniaturization design of earphones poses a challenge for the built-in high-performance audio processor and maintaining long-term battery life. Moreover, earphones need to have enough intelligence to process and adapt to audio signals in different environments to provide the best listening experience.

Huawei FreeBuds Pro 3 has achieved many breakthroughs in audio technology. The headset uses the Kirin A2 audio chip developed by Huawei, which is equipped with high-performance audio processing capability. Compared with the traditional Bluetooth, the bandwidth of Kirin A2 chip is four times higher, and its computing power is two times higher than that of the previous generation. This ensures that even in complex wireless environments, the audio signal can be accurately decoded to maintain the purity and integrity of the audio quality. Polar code technology can improve the transmission stability, and also provide the headset with a larger transmission distance and better anti-interference capability. Kirin A2 chip and Polar code technology jointly improve the stability and efficiency of transmission, which is particularly important in mobile environments. The user's experience in the mobile process will not be affected by signal problems.

In addition, to achieve high-speed lossless audio transmission, the upgrading of encoding and decoding technology is also crucial. The L2HC 3.0 independently developed by Huawei is a new generation of intelligent audio codec transmission protocol. Compared with the mainstream encoding and decoding formats such as AAC and SBC, L2HC 3.0 has obvious technical advantages in high-speed transmission. It can support ultra-high bit rate up to 1920Kbps, far exceeding the industry average. Huawei FreeBuds Pro 3 can realize stable transmission of 1.5Mbps lossless audio signal and perfect reconstruction of lossless audio quality when cooperating with Huawei Mate60 series mobile phones.

In addition to hardware innovation, Huawei has also done a lot of work on software and algorithms. Relying on the HarmonyOS system, Huawei FreeBuds Pro 3 is equipped with a real-time optimization algorithm for triple sense of hearing, which can adjust the sound quality in real time according to the user's hearing structure and wearing status, and provide a more personalized hearing experience. This means that Huawei's FreeBuds Pro 3 can provide the best sound quality performance for users in any environment.

Acoustic design is not only a technical project, but also an art

Huawei regards acoustic engineering as an end-to-end system problem. Every step has been carefully polished and optimized, from the miniaturized design of hardware to the detailed restoration of sound quality. The combination of Huawei FreeBuds Pro 3 and Mate60 series mobile phones shows Huawei's ecological advantages. The seamless connection between the headset and the mobile phone not only provides convenience, but also optimizes the audio experience through deep integration, so that the 1.5Mbps lossless audio quality can be achieved on the real wireless headset.

Huawei's systematic engineering method is not limited to the technical level. The acoustic performance of Huawei's FreeBuds Pro 3 has also benefited from the cooperation with the chief tuning group of the Central Conservatory of Music, and has been greatly improved. Huawei engineers work closely with top music experts to jointly research and debug, so that Huawei FreeBuds Pro 3 can accurately restore the original intention of musicians and producers in terms of sound quality, and bring users a near scene hearing experience.

Bravely explore the future of audio

After the brutal growth period of real wireless headphones, today's users have higher requirements for sound quality, and lossless sound quality will become the focus of the future development of the real wireless headset industry. Huawei has laid a solid foundation for transmitting lossless audio for many years, and has finally achieved this goal through continuous technology research and development and iteration. With the launch of Huawei's FreeBuds Pro 3 headset, Huawei has set a new benchmark for users and the entire audio industry. Huawei has broken the metaphysics of sound quality with its own audio technology strength, scientifically quantified audio, and brought the true wireless headset to a new stage of development. It will be a thing of the past for a real wireless headset to only "listen". Huawei FreeBuds Pro 3 is not only a milestone for Huawei in the audio field, it also indicates the future development direction of the entire industry.
