"Le audio" standard appears, and domestic Bluetooth headset manufacturers can hang up all kinds of brands

With the emergence of Le audio standard, the domestic Bluetooth headset manufacturers and wholesalers are excited. In the future, the Bluetooth headset will no longer be a thousand yuan market, and the hundred yuan Bluetooth headset will no longer only listen to the sound, bypassing patent protection. The Bluetooth headset will no longer be the world of brand manufacturers. Today, the Bluetooth headset manufacturer will introduce the Le audio standard in detail?

As we all know, since the appearance of Bluetooth headset, the sound quality has been criticized, but also can not be seen by professionals. Even though the Bluetooth standard has developed to the fifth generation, the sound quality, endurance and function of Bluetooth headset have not been improved. Mobile phone headset headset hole make complaints about the headset. The most common tucking is Bluetooth headset. The short sound quality is not good enough, and it is not even available at the same price. But Bluetooth headsets may change. Because not long ago, Bluetooth Technology Alliance released the latest generation of Bluetooth audio technology standard "Le audio".

Many people know that listening to music through wireless headphones depends on the audio transmission protocol, which compresses the audio data on the mobile phone and then transmits it to the Bluetooth headset. But whether its Bluetooth 4.0, 5.0 or the latest Bluetooth 5.1 headsets, when we use them to listen to songs, we actually use the A2DP protocol that already exists on Bluetooth 2.0. The old protocol nine years ago didnt have much bandwidth (the amount of data that can be transmitted per second) for Bluetooth headphones to transmit high-quality audio data. If you want higher audio quality, you can only rely on high-quality compression algorithm. The reason is very simple, the same volume of puffed biscuits and compressed biscuits, the latter after compression of the component is significantly heavier than the former, eating is also easier to fill the stomach. For example, 索尼s LDAC, Huaweis Hwa, Qualcomms apt-X and other encoding and decoding technologies are launched to compress the audio data as much as possible, so as to improve the audio quality.

But in the final analysis, the previous encoding formats are all audio data transmitted through A2DP traditional protocol, and the power consumption is still very high when listening to songs. Especially for the real wireless Bluetooth headset, you need to worry about its endurance after listening for three or four hours. Whats more, the cheapest Bluetooth headset coding technology is the most popular SBC coding format. These headphones are not related to the words "high quality and low power consumption". Unlike the traditional Bluetooth protocol, Le audio can transmit audio with low power consumption, and it also provides a new high-quality audio codec LC3. Compared with SBC, LC3 code has a higher compression rate. Although the sound quality is not as good as LDAC, it uses the same low-power channel as sports bracelets and other devices, so it is much better than them in terms of power consumption.

Using LC3 instead of SBC can make the headsets endurance longer under the original volume, and the volume of Bluetooth headset can continue to be smaller under the condition of constant endurance. Not only that, Le audio also supports a device to connect multiple Bluetooth at the same time, and can transmit multiple independent synchronous audio streams when connecting. This means that other Bluetooth headset manufacturers can bypass the TWS technology patents of apple and Qualcomm, and do not need to pay for chips or develop their own solutions to connect the two headsets to the mobile phone at the same time. No matter which brand of Bluetooth headset you buy, it can be compatible with our mobile phone, instead of only playing the maximum performance of the headset on your own mobile phone and achieving the minimum delay as before. Before le audio came out, the market Bluetooth headset, especially TWS headset, can be said to be two-level differentiation. The experience of thousand yuan level and hundred yuan level TWS headset is very different.

For example, Apples airpods, 索尼s wf-1000xm3 and Huaweis freebus 3 have all built-in chips, which enable headphones to have better sound quality and support simultaneous connection of both ears. And those cheaper wireless headphones because of the cost, patent, technology and other thresholds, in the headphones sound quality, endurance, delay or volume is difficult to compare with them. Therefore, we can often see that these Bluetooth headsets are either very large in volume, very poor in sound quality, or extremely slow in pairing. We can only pair two headsets before connecting them to the mobile phone. At least after the release of Le audio Bluetooth audio technology, various Bluetooth headset manufacturers can directly update the protocol at the software level, so that their earphones can use Le audio with better sound quality, longer life and more functions.

After understanding Le audio standard, you should know why Bluetooth headset manufacturers and wholesalers are excited. To solve the problem of endurance and sound quality, the basic core problem of Bluetooth headset is to solve the popular point. If Bluetooth headset can have a greater breakthrough in sound quality, it is the pursuit of Bluetooth headset manufacturers.
