What is TWS headset
TWS is the abbreviation of True Wireless Stereo in English, which means true wireless stereo. TWS technology is also based on the development of Bluetooth chip technology. According to its working principle, it means that the mobile phone is connected to the main earphone, and then the main earphone is quickly connected to the secondary earphone in a wireless manner, so as to realize the wireless separation of the left and right channels of Bluetooth. When the slave speaker is not connected, the main speaker returns to monaural sound quality. TWS technology has been applied to the field of Bluetooth headsets, so a new product-TWS Bluetooth headsets was born.
To trace its development process, we have to start with Apple. In 2017, the removal of the 3.5mm jack on iPhone 7 led to the rapid development of the Bluetooth headset market. Of course, Bluetooth headset technology and products have also been developed for many years. Among them, the products and quality are also uneven, and the industry is chaotic. Until Apple took the lead in releasing the world’s first TWS Bluetooth headset AirPods, this product supports the connection of many of Apple’s ecological products (Iphone, Ipad, iwatch, Macbook), and wireless headsets have built-in optical sensors and accelerometers. Double-click this wireless headset to connect to Siri. During the user’s call, this headset can also reduce noise and filter noise to ensure sound quality. At the same time, the field of AI at home and abroad is booming. With the help of AI, TWS technology rides the express train of the “smart” era. Since then, Bluetooth headsets have given new vitality.
TWS has those characteristics
1. True wireless can achieve single and double ear wearing
The TWS Bluetooth headset does not require a wired connection, and gets rid of the shackles of traditional headsets. The two left and right headsets form a stereo system through Bluetooth, which improves listening, talking, and wearing. If you add professional acoustic pickup technology, intelligent noise reduction technology & AI algorithm noise reduction technology, you can achieve a perfect sound experience: ear-worn voice, video calls, music enjoyment, mountain climbing, safe driving, etc. are not restricted .
2. Intelligent noise reduction function
From the product point of view, the noise reduction function is an essential technology. Audio and video experience is the focus of users’ attention on TWS headsets. We can design product application scenarios, but we cannot guarantee that users will always apply your product in the scenarios you design. When we dig deeper into certain products in the industry , I found that many users complained that outdoor noise reduction is too bad, such as a certain Sony product has been complained; Aola BES50XS series in overseas and airports, unable to hear the sound transmitted to us in the headphones, we measured QCY when getting on and off the subway Direct breakpoints, these poor user experience make the product greatly discounted.
3.semi-intelligence & intelligence
In the era of crazy development in 2018, the TWS headset has experienced the road of semi-smart headsetization. Take the smart TWS Bluetooth headset represented by asking questions as an example. It is not only a hardware product, but also carries in-depth content in the APP. Immediately transformed into a smart interactive smart product; the same more Bluetooth chip manufacturers have been upgraded on version 5.0, embedded serial flash memory, can more flexibly upgrade customer software, support third-party software migration; cooperate with The original ecology or content provider (audio content, headline news, health information, financial news, sports information, etc.) opens its ports, and in fact there is a lot to do in the content. The mainstream first-line gods have been involved in the field of artificial intelligence, and they are all building their own intelligent ecological chain. Foreign countries take Microsoft, Google, and Amazon as examples to extend Microsoft Cortana, Google Assistant, and Amazon Alexa wireless intelligent voice interaction services. Behind it is a The battle for smart end users. The representative of the new generation is the GT100 product of Braun Acoustics. Behind it is a professional acoustic team doing the most advanced acoustic research and development in the industry. Of course, APP supports the above-mentioned ecological content involved.
Similarly, domestic hardware manufacturers, represented by mobile phone manufacturers, support their voice assistants. Huawei’s TWS supports Xiaoyi in their mobile phones, and Xiaomi TWS supports Xiaoai students. This aspect is particularly important. The era of intelligence has come, and pure hardware is more important. Most are labels that advertise low-end products, because no one wants to spend the same money to buy a cheap hardware product. In Q3-Q4 of 2019, it is expected that the sales of smart speaker products + TWS smart headset products will increase significantly, which will promote the faster development of the field of artificial intelligence.
Why is TWS so popular?
Let me first talk about the market of wired earphones. According to industry statistics and professional market research institutions, the market for wired earphones is over 100 billion U.S. dollars every year! With the support of TWS technology, you can completely say goodbye to all kinds of cut and unclear wired earphones-when you enjoy music, not only between the media source and the earphones, but also between the left and right earplugs. No cables required! The embarrassment brought by the earphone cable over the years is finally becoming history. And the author believes that with the upgrading and updating of TWS technology, there will be greater breakthroughs in the field of acoustic noise reduction, and once the volume of the entire TWS industry breaks through, the cost of chips and solutions will drop. It is expected that in the next two to three years During the year, TWS headsets will become the standard equipment shipped by mobile phone hardware manufacturers.
According to the actual measurement data, the mainstream use range of the market is 10 meters, and the farthest is only 12 meters. At this stage, based on the domestic application scenarios, it is obviously unable to meet the user experience needs. Who can solve the problem of transmission distance means having an absolute advantage in this industry!
