has finally arrived at the final chapter of this series. In the previous three articles, we take Apple's cut off the 3.5mm interface when it released iPhone 7 in 2016, and briefly reviewed the impact of this behavior on industry development and consumption behavior in the past two years from different angles. With the cancellation of the 3.5mm headphone interface, Bluetooth 5.0 has been rapidly popularized. In 2018, we have seen more and more Bluetooth headphones and true wireless Bluetooth headphones appear. Many friends around me have also replaced Airpods, and only I am still insisting on using 3.5mm headphones.

Bluetooth 5.0 and true Bluetooth wireless headphones concept

Bluetooth and Bluetooth 5.0

First we need to understand what Bluetooth is, what can be done, and what effect can it have.

Since the birth of Bluetooth technology, signal transmission has a new way. Its innovative significance is not just to simply "remove" that wire. In fact, before Bluetooth appeared, other wireless transmission technologies have begun to be applied to all walks of life. In addition to having wireless transmission distances of several meters or even dozens of meters, Bluetooth has a better development environment from beginning to end, which has created its very broad equipment adaptability.

To this day, the Bluetooth version has continued from the initial version 0.7 in 1988 to the widely used series of versions 3.0 and 4.0 later, while the latest Bluetooth 5.0 was released in June 2016. This update not only greatly increased the transmission distance to 300 meters (theoretical data, 4 times the old version), and the bandwidth of transmission has doubled, but also made greater improvements to several other parts of the world: accurate positioning with an error of 1 meter, IoT functions, stronger data transmission functions, and lower power consumption.

upgraded version of Bluetooth audio transmission

returns to wireless audio transmission. If we only use Bluetooth to transmit audio, we will not hear better sound quality, which involves wireless high-standard transmission protocol.

Bluetooth 5.0 is just an untouched, wide highway that can accommodate many cars, but if the planning and use is unreasonable, it will still cause traffic jams and crashes. The wireless transmission protocol is equivalent to how to efficiently use the Bluetooth 5.0 highway.

If ordinary Bluetooth protocols are used (such as A2DP protocol, SBC encoding), high-quality music will be forced to compress the sound quality due to slow transmission speed, affecting the final sound quality effect. If a more advanced wireless transmission protocol is used, the music in the phone can be transmitted losslessly to Bluetooth headphones, just like wired headphones, ensuring the authentic sound quality. This is also the reason why Bluetooth headsets and devices that support high-speed transmission protocols are more expensive.

Currently, there are three mainstream and recognized high-standard wireless transmission protocols in the market: SONY LDAC, Huawei HWA and Qualcomm APT-X HD. Therefore, when purchasing Bluetooth devices (such as mobile phones) and headphones, in addition to identifying Bluetooth 5.0, you also have to see if these three high-speed protocols are supported, and the high-speed protocols of the headphone end and Bluetooth device end (such as mobile phones) need to match each other. The great iPhone currently does not support either.

is good. In addition to the high-quality Bluetooth audio transmission protocol, there are also wireless Bluetooth headphones and true wireless Bluetooth headphones. What are true wireless Bluetooth headsets?

To this day, we can see that there are fewer and fewer flagship phones with 3.5mm headphone interfaces.With the emergence of Airpods, more and more manufacturers have launched various true wireless headphones, and the Bluetooth headphone market has ushered in a new round of explosion. In 2018, the industry's sales volume for Airpods is expected to be 26 million. According to Apple's financial report, smart wearable devices are growing rapidly. However, because Apple has not officially subdivided Airpods separately, the industry's sales of this headset are estimated to be 6 billion.

In 2018, we saw that more and more true wireless Bluetooth headsets appeared in manufacturers - TWS-True Wireless Stereo. Many companies have launched their own solutions, and corresponding representative products can be found in the market such as AIROHA AB1526, BES Hengxuan Technology BES2000IZ, Qualcomm CSR8675/8670 and other solutions.

's current main solution is to connect to the mobile phone Bluetooth through a main channel headset, and then synchronous interconnection between the left and right channels is completed through low-frequency communication. Transmitting data through relay means that while receiving the audio stream from the mobile phone, one earbud also acts as a repeater to send audio to the other earbud, which will undoubtedly generate greater power consumption and have a higher latency throughout the experience. Moreover, even though the CSR8675 nominally supports Bluetooth 5.0, its actual bandwidth is still 1Mbps, which is not the real Bluetooth 5.0. The common disadvantage of this type of product is that their power management capabilities are somewhat insufficient, and the final product has poor battery life and slow charging speed.

In mid-2018, Qualcomm released the QCC5100 and QCC302x/303x series chipsets, and finally saw the release of the QCC3026 chipset Bluetooth headset products at the end of the year and at CES2019. Qualcomm's new chipset, combined with the Snapdragon 845 and /new 6 series/7 series mobile phone chipsets, can achieve true wireless transmission with full independent dual channel transmission under true Bluetooth 5.0. Qualcomm calls it True Wireless Plus. Under this connection technology, there will be two independent audio streams directly transmitted from the phone to two different headphones. During use, the headphones first communicate with the phone. If the phone is based on the Snapdragon 845, 670, and 710 mobile platforms, the headphones will automatically switch to TrueWireless Stereo Plus mode. At this time, Airpods real wireless headphones have been released for more than two years, and Apple is amazing.

The new vitality after cutting off the 3.5mm headphone interface

Now looking back at Apple's behavior at that time, it is indeed a bit like "nothing can be lost, no one knows how to be blessed." Cutting off a 3.5mm interface gives audio manufacturers a new development direction and brings consumers a richer product choice. Due to its morphological advantages, Bluetooth wireless products guarantee sound quality based on Bluetooth 4.0 or above protocol, and the unique sound training of major manufacturers, the performance of Bluetooth audio hardware can also meet the needs of the public consumers for sound quality.

However, consumers are forgetful. Being able to forget the criticism of being forced to transfer from a 3.5mm interface to a Bluetooth connection back then will gradually forget the beauty of the current products and become more and more picky about product demands. Manufacturers have naturally already seen the changes in consumers' mentality. Therefore, as Bluetooth audio products are gradually permeating into consumers' lives, the Bluetooth transmission protocol is being updated. Is the Bluetooth audio market ushering in a good opportunity to set off another climax? Why is the real Bluetooth 5.0 not coming for a long time?

Compared with the previous Bluetooth protocol, the update of Bluetooth 5.0 is mainly aimed at distance, ultra-low power consumption and stability. For Bluetooth audio products, these three points can further meet consumers' needs in user experience. Compared with plug-and-play wired headphones, battery life and stability are the primary considerations for consumers when purchasing Bluetooth headphones. Since that's the case, why haven't we seen manufacturers on the market place large-scale products using Bluetooth 5.0 chips? The chips that support Bluetooth 5.0 specifications that support

are actually not too late. At CES 2018, chip giant Qualcomm has released chips that support Bluetooth 5.0 specifications at various levels, providing a solid foundation for manufacturers to further explore Bluetooth products. However, more than a year has passed, and Qualcomm, as an industry giant, has not allowed audio manufacturers to use the 5 series Bluetooth chips stably.Most mobile phones that most consumers are used to play music wirelessly are also staying in the era of Bluetooth 4.0, so we have not yet felt the improvement brought by Bluetooth 5.0. Although the Qualcomm 3 series Bluetooth chip, which has gradually been distributed to the market, has the advantage of comparing chips that support Bluetooth 4.2 specifications in terms of parameters, it does not reflect the significant improvements in Bluetooth 4.2 specifications in actual product applications. On the one hand, the cost has increased, but the actual experience, especially the sound quality performance, has not improved much. On the other hand, the suppliers have many choices, the cost control is mature, and the 4.2 standard chips that the manufacturer has obtained, the essence of the merchant will drive all manufacturers to make the most suitable choices at the emergence stage.

In our opinion, when the two specifications exist at the same time, they will inevitably alternate. Whether it is for suppliers or manufacturers, there is still a lot of room for operation. During the period when Qualcomm 5 series chips are gradually being placed on the ground and still count as a vacuum, whether third-party manufacturers can overtake, or follow up and launch competitive models after the mass production of Qualcomm 5 series chips is an important node that determines the impact of the future Bluetooth 5.0 specification on the market. Based on this situation, there are still many variables in the Bluetooth audio market in the next two or three years. What impact will these variables have on consumers' choices? We still don't know now. But there are two points that can be confirmed: if you like to pursue new technologies, you can wait for a while and make a decision after the Bluetooth 5.0 audio product is popularized; if you are in a hurry to buy a Bluetooth audio product, based on identifying the high-definition music transmission protocols such as aptX/LDAC, and purchasing the protocol supported by the playback device in your hand can also achieve satisfactory results.

Looking around manufacturers and consumers about the Bluetooth audio market, the prosperity of the Bluetooth audio market actually does not break the traditional wired headphone market pattern, but instead shows a prosperous pattern of "two blossoms of culture and sports". Just as electronic paper books are gradually spreading out and paper books still have audiences, Bluetooth and wired actually have no distinction between good and bad. What we should talk about between them is how to find a form that can meet your needs in different occasions, so that the immersive sound experience can be accompanied at any time and feel the emotions flowing in the notes.

Currently, Bluetooth headsets generally have the following problems: 1. Bluetooth connection is unstable and is easily disturbed by electromagnetic waves (too many devices in the 2.4GHz band). 2. If the battery life is not strong, you need to charge it frequently (I don’t know how much Bluetooth 5.0 can change). 3. Sound delay, especially in some games. I hope that this time Bluetooth 5.0 will bring some qualitative changes. After all, we can no longer go back to the wired era, and the wireless era is the general trend.
