With the continuous popularization of smart wear, TWS Bluetooth headsets have become an indispensable personal item for most mobile phone users. With the introduction of NTC thermistor as temperature monitoring components and the gradual improvement of technology, TWS Bluetooth headsets have become more and more intelligent, with a wider range of applications in addition to audio entertainment, such as health, fitness, personal assistance and so on.

With the addition of NTC thermistor, TWS Bluetooth headsets can help users take necessary health precautions in advance. Since the outbreak of the COVID-19, people have paid special attention to their health. Using the characteristics that the resistance value of a thermistor changes with temperature, it can assist TWS Bluetooth headsets to monitor the user's ear canal temperature in real time, if there is an abnormality, the collected temperature data will be immediately fed back to the mobile phone, prompting the user to pay attention to their own body temperature.

The increasing health awareness of users is a key factor in the growth of the market of TWS Bluetooth headsets, which can record relevant data more accurately, effectively and quickly through NTC thermistor for real-time ear canal temperature monitoring, providing users with health reference. Due to the temperature of the ear canal is closer to the core temperature of the human body, the ear drum has the same source of blood supply as the hypothalamus, the body temperature control center of the brain, so the ear can reflect changes in body temperature more quickly than other locations. And the headsets are always in contact with the ear canal part, which further improves the accuracy of data measurements.

The SMD type NTC thermistor independently developed and produced by EXSENSE Electronics Technology Co., Ltd. has the characteristics of high accuracy, rapid response and small size, which is in line with the development direction of miniaturization, intelligence and convenience of TWS Bluetooth headsets, and can protect the improvement of the ear canal temperature monitoring function of TWS Bluetooth headsets.
