According to IDC, as the penetration rate of TWS headphones continues to increase, the market gradually presents a saturated state, and the TWS market in 2023 will mainly focus on the development opportunities brought by technological function innovation. According to the "Audio product use Status Research Report 2023" shows that 70% of the respondents listed lossless sound quality as a potential purchase driver, all signs are that, with the unprecedented prosperity of the wireless audio market, people also put forward higher requirements for their use experience, and lossless sound quality will become the future direction of development.
Due to technical limitations such as traditional Bluetooth transmission protocol loss, most TWS headphones have been difficult to achieve lossless sound quality for a long time. At this year's Huawei autumn all-scene conference, Huawei brought the world's first true wireless Bluetooth headset that supports 1.5Mbps lossless sound quality - Huawei FreeBuds Pro 3 has a built-in Kirin A2 audio chip equipped with Polar code technology (the core technology of starflash connection). For the first time, it presents the full sound color and beautiful details of ultra-CD lossless sound quality on Bluetooth headphones, setting off the sound quality revolution of Bluetooth headphones!
On November 23, Huawei held the 2023 Huawei Audio Innovation Technology Media Communication Meeting at the Opera Concert Hall of the Central Conservatory of Music, and shared the acoustic innovation technology behind FreeBuds Pro 3 with guests, media and listeners on the scene. After the meeting, Huawei technical experts and on-site guests also carried out a roundtable discussion around the theme of "lossless audio, restoring art with technology". After the round table discussion, musicians from the Central Conservatory of Music also performed a "leading acoustic" concert for on-site guests.
In this Huawei Audio innovation technology media communication meeting, the guests on the spot also gave high praise to the "acoustic" listening sense of FreeBuds Pro 3. The media listened to the songs of the concert through the FreeBuds Pro 3 on the spot. Also can not help but feel the charm of "acoustic listening" brought by the terminal equipment of headphones, which is the same as the concert scene. In short, let's reveal the mystery behind Huawei FreeBuds Pro 3 to achieve ultra-CD-level lossless sound quality.
The TWS headphone market has been competing for better sound quality, but achieving lossless sound quality has been an insurmountable mountain for the industry. It is not easy to hear a piece of audio on TWS headphones, which requires audio acquisition and production, music App distribution, mobile phone codec, audio signal transmission, headset coding and acoustic unit playback. More importantly, sound quality may be impaired at each step, and it is more difficult to obtain lossless hearing. Any end of the entire listening link from the mobile phone to the headset to the human ear is not polished in place, and it is impossible to perfectly restore the lossless audio. It can be said that the difficulty of audio technology development and landing is just like dancing on the tip of a knife.
Huawei has been deeply engaged in the audio field for 10 years, and after a lot of long-term investment, it has held hundreds of invention patents in the field of TWS headphones alone, and launched the world's first audio chip supporting Polar code technology - Kirin A2 this year, with the support of this technology, Huawei FreeBuds Pro 3 has powerful audio signal transmission capability.
Thanks to the fast transmission, low power consumption, high performance and high integration of the Kirin A2 chip, the anti-interference ability of Bluetooth audio Bluetooth transmission is increased by 2 times, and the industry's first 1.5Mbps lossless sound quality signal transmission, so that users can finally enjoy ultra-CD true lossless sound quality. With the surging power of Kirin A2, Huawei FreeBuds Pro 3 has also achieved revolutionary improvements in sound quality, connection, noise reduction, call and other aspects.
If the Qylin A2 chip is the "engine" of full-link lossless sound quality, the industry's first application of Polar code technology and Huawei's self-developed L2HC 3.0 protocol is the "driver", and the combination of strong and powerful can completely cross the mountain of full-link lossless sound quality.
In order to further realize the transmission of lossless sound quality, Huawei FreeBuds Pro 3 is based on Huawei self-developed Super Bluetooth technology. The maximum physical speed of Bluetooth is increased by 4 times compared with the bandwidth of 2Mbps of ordinary Bluetooth, reaching 8Mbps, which is like increasing the number of cargo ships allowed to pass through rivers per second. This also laid a good foundation for more detailed sound creation.
For "with the improvement of the bitrate of audio signal transmission, the anti-interference ability of audio signal will be significantly reduced", which is a well-known technical pain point in the industry. Huawei uses Polar code, the core technology of starflash connection, on FreeBuds Pro 3. The addition of this technology undoubtedly provides the "golden bell cover" -like protection ability for audio transmission of 1.5Mbps, which makes the anti-interference ability of FreeBuds Pro 3 and Huawei Mate60 series mobile phones increase by two times compared with the previous generation. It can effectively resist external interference during audio transmission, so as to be more stable.
After solving the "transmission" problem, the "dock" and "code tail" that play the role of connecting the two ends can not fall, and the audio codec is a strong support for the front and back end of lossless transmission. Huawei FreeBuds Pro 3 supports Huawei's new self-developed L2HC 3.0 protocol, has the industry's current mass production, the highest wireless audio transmission capability, can be called the industry's "ceiling", can effectively reduce the audio transmission process sound quality damage.
It is worth mentioning that Huawei has previously announced the open source L2HC 3.0 to the whole industry, a feat that will surely promote the wireless audio industry to upgrade again. The new L2HC is currently the only audio codec standard that exceeds the CD-level lossless music transmission bit rate requirement (1.41Mbps), and its arrival can not only help more partners in the industry chain to launch lossless audio products, but also set the benchmark for the entire Bluetooth audio industry.
This is not enough, in order to achieve complete "lossless restoration", it is necessary to have a sound unit that takes into account the broadband domain, low distortion and high transient. Huawei FreeBuds Pro 3 is equipped with ultra-sensing acoustic dual units, the treble unit uses Helbeck magnet array, the bass unit is a big drive 11mm super-magnetic induction unit, coupled with digital frequency division technology, accurately restore the rich details and full sound of lossless audio, which is charming.
In terms of software level algorithm, Huawei FreeBuds Pro 3 also adopts the newly upgraded triple hearing real-time optimization algorithm, which can optimize the wearer's hearing in an all-round way according to the volume size, human ear structure and wearing status, and become the most "understand" you wireless headphones.
Hearing is a complex sensory system that depends not only on the shape of the ear and the level of hearing, but also on emotions, experiences, and health states, so that many music enthusiasts often fall into the spell of sound quality and think that "the end of sound quality is metaphysical."
As a leader in the smart audio industry, Huawei insists that acoustics is an end-to-end systematic engineering, a quantifiable science, not a metaphysics. In the Huawei FreeBuds Pro 3, we can see that Huawei has brought the core technology of full-link lossless sound quality with more than ten years of accumulation in the audio field, and has "connected" back the cut line of Bluetooth headphones, and finally achieved the industry's first headphones to achieve ultra-CD-level lossless sound quality.
The advent of Huawei FreeBuds Pro 3 has opened a new era of lossless sound quality of TWS headphones, and also made the sound quality of TWS headphones move from "high-definition" to "lossless". As the biggest contributor behind it, Huawei has always been like a boundarybreaker with hardware and software capability integration and innovation, and the ability to jump out of the traditional technical framework. Let the small headset have a big world again and again, let the sound quality from metaphysics to science!
