What is a TWS headphone?

TWS headset, True Wireless Stereo, true wireless stereo (headset), because it mainly uses Bluetooth technology for transmission, so now everyone prefers to call it true wireless Bluetooth headset. Since there is no physical connection between the left and right units (main and auxiliary earphones) of the TWS earphones (there is no 3.5mm cable), the TWS earphones are not directly charged through the USB interface, but are charged through a portable box with both charging and storage functions. When the battery is not enough, just put the earphones in the box, the earphones will be automatically disconnected and charged.

The reason why TWS headsets really detonated the market is that during the same period, the Android camp experienced the same unified interface change: when the traditional USB charging interface is moving towards the USB 3.1 standard, it faces the choice of a Type-C interface that supports positive and negative insertion and is lighter and thinner. (I.e. USB-C). At the same time, the traditional 3.5mm interface also faces the problem of leaving and leaving on Android phones.

Technical pain points of TWS headphones

Whether it is Airpods or other brands of TWS headphones, it can be said that they are products that conform to the trend. In addition to avoiding the problem of removing the 3.5mm interface of the mobile phone, it needs to be equipped with an adapter cable. At the same time, it also enables one device for dual use (for example, some TWS headsets can wake up the AI voice assistant by double-clicking the left earphone, and double-click the right earphone to switch music and other operations. ). These functions have the possibility of success.

Although as early as 2011, the iPhone 4S released by Apple was equipped with the intelligent voice assistant Siri (AI artificial intelligence), but the mainstream human-computer interaction method for smart phones was still the touch method, and it failed to move forward to the voice method as desired. For the time being, smart phone manufacturers would rather continue to upgrade their cameras and focus on taking pictures as a selling point, allowing people to use their phones more for photography, rather than picking up smart voice assistants as a selling point and spending a lot of money on promotion. However, smart phone manufacturers are more willing to try to apply the smart voice function on TWS headsets as a voice pilot. In fact, this is completely understandable. After all, compared to the multi-scenario application of smart phones, TWS headsets are more suitable for smart voice functions because they focus on voice application scenarios. Therefore, equipment manufacturers have also paid attention to and improved this function. 

From the perspective of the number of patent applications, invention patents account for 26.5%, utility models 37.9%, and appearance designs 35.6%. Today, when basic technology is more homogeneous, manufacturers pay more attention to the design, processing and use of external factors. From the perspective of whether the company is a high-tech company, nearly 40% of TWS headset companies are high-tech companies.
