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 auxiliary earphone by wireless means, so as to realize the true wireless separation of the left and right channels of Bluetooth. When the slave speakers are not connected, the master speakers return to mono sound quality. TWS technology has been applied to the field of Bluetooth headsets, so it has also spawned a new product - TWS Bluetooth headsets.
To trace its development process, we have to start with Apple. In 2017, after the iphone7 canceled the 3.5mm jack, the Bluetooth headset market has developed rapidly. Of course, Bluetooth headset technology and products have also developed for many years, and the products and quality are also uneven, and the industry is in chaos. Until Apple first released 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 the wireless headset has built-in optical sensors and accelerometers. Double-tap this wireless headset can also access Siri. During the user's call, this headset can also reduce noise and filter noise to ensure sound quality. At the same time, the AI field at home and abroad is developing vigorously. TWS technology takes advantage of the potential of AI and rides the express train of the "smart" era. Since then, Bluetooth headsets have given rise to new vitality.
TWS earbuds' characteristics:
1. True wireless can be worn on both ears
The TWS Bluetooth headset does not require a wired connection, which is free from the shackles of traditional headsets; the left and right two headsets form a stereo system through Bluetooth, which improves listening to songs, calls, and wearing. If you add professional acoustic pickup technology, intelligent noise reduction technology & AI algorithm noise reduction technology, etc., you can achieve a perfect sound experience: ear-worn voice, video calls, music enjoyment, climbing and running, safe driving, etc. are not restricted ;
2. Intelligent noise reduction function
From a product point of view, noise reduction is an essential technology. Audio and video experience is the focus of users' attention on TWS headsets. We can design application scenarios for products, but we cannot guarantee that users will always apply your products in the scenarios you design. When we dig deep into some products in the industry , found that many users complained that the outdoor noise reduction is too poor, and these poor user experiences greatly reduced the product.
3. Semi-intelligent & intelligent
TWS earphones have gone through the road of semi-smart earphones in the era of crazy development in 2018. Take the smart TWS Bluetooth earphones represented by going out and ask as an example. It is not only a hardware product, but also carries in-depth content in the APP. Immediately transformed into an intelligent interactive intelligent product; also more original Bluetooth chips have been upgraded in version 5.0, embedded serial flash memory, can be more flexible to upgrade customer software, support third-party software migration; The original ecology or content provider (audio content, headline news, health information, financial news, sports information, etc.) will open its port, in fact, it has a lot to do in the content. The mainstream gods have been involved in the field of artificial intelligence and are building their own intelligent ecological chain. Taking Microsoft, Google, and Amazon as examples abroad, Microsoft Cortana, Google Assistant, and Amazon Alexa wireless intelligent voice interaction services have been extended. The battle for smart end users.
