Please stop charging at this time and start checking the power. If the battery is not fully charged, please continue to the next step.
The indicator light (red) may not turn on or off until the charging is completed for the following reasons:
1, headphones have been useless for a long time.
When the Micro-USB cable is connected to charge the earphone, the indicator light (red) may not light up. In this case, do not disconnect the Micro-USB cable from the earphone, and wait for a few minutes until the indicator light (red) lights up.
Tip: If the earphone is stored for a long time, please fully charge the battery every 6 months to avoid excessive discharge.
2. The ambient temperature exceeds the charging temperature range of 5 C–35 C.
In this case, the indicator light (red) may also go out or flash. Please recharge when the temperature reaches the charging temperature range.
When the computer is connected to the earphone, it will go into sleep mode.
If the computer enters hibernation mode, it will not be able to charge normally, and the indicator light (red) will go out automatically. In this case, please reset the computer and charge the headset again.
4. There is something wrong with the battery
Bluetooth technology is an open global specification for wireless data and voice communication. It is a special short-distance wireless technology connection based on low-cost short-distance wireless connection, which establishes a communication environment for fixed and mobile devices. [ 1]
Bluetooth enables some portable mobile devices and computer devices to connect to the Internet without cables, and can access the Internet wirelessly.
1 Bluetooth hands-free communication.

The application of Bluetooth technology in car hands-free system is the most typical application technology of Bluetooth in cars. With the mobile phone as the gateway, the Bluetooth function of the mobile phone and the car hands-free system can be turned on. As long as the mobile phone is within the range of the car hands-free system 10 meter, it can automatically connect and control the microphone and sound system in the car, and realize full-duplex hands-free conversation. Using the in-vehicle handsfree application framework as the basis of Bluetooth handsfree communication technology, Bluetooth devices are well standardized and Bluetooth function sets are collected, so that Bluetooth technology can be controlled. [4]
2 car Bluetooth entertainment system.
Car Bluetooth entertainment system mainly includes USB technology, audio decoding technology, Bluetooth technology and so on. Based on the above technologies, the microphone and stereo in the car are used to play all kinds of audio and phone books stored in the U disk, and pop music and other playing functions are added. Connecting the network in the in-vehicle system based on CAN can realize the operation of the in-vehicle infotainment system. At the same time, it also retains the scalability of the system. [4]
Remote condition diagnosis of bluetooth car.
On-board diagnosis system mainly relies on Bluetooth remote technology to maintain the vehicle in time, especially to monitor the automobile engine in real time to help the vehicle grasp the specific operation of different functional modules at all times. Once the system is found abnormal, the set calculation method is used to accurately determine the cause and type of the fault, and the fault diagnosis code is uploaded to the memory of the on-board operating system. It's more convenient and faster to pick up. [4]
4 car Bluetooth anti-theft technology.
With the gradual maturity of technology, Bluetooth will be further improved in its wide application, security, transmission accuracy and transmission efficiency. Especially in the application of Bluetooth burglar alarm, if the car is in a fortified state, the Bluetooth sensor function will automatically connect to the owner's mobile phone, and once the car state changes or is stolen, it will automatically give an alarm. The application of Bluetooth anti-theft technology provides a safer environment for cars. [4]
The second is the application of Bluetooth technology in industrial production.
1 Technician's wireless monitoring of CNC machine tools.
The application of Bluetooth technology in CNC machine tools is mainly reflected in wireless monitoring. Using Bluetooth technology to install the corresponding monitoring facilities provides convenience for the production of CNC machine tool users, and also maintains the safety of CNC machine tool production. Technicians can monitor and manage the operation of machine tools at any time according to the Bluetooth monitoring equipment they carry with them, and solve the production problems of CNC machine tools in time. In particular, the automatic monitoring ability realized under the wireless data link can properly interfere with the operation of the machine tool, such as stopping the spindle or stopping the system. [4]
2. Inspection of parts wear degree.
Bluetooth detection function is also reflected in the wear of industrial parts. Using Bluetooth detection software combined with wear detection materials to carry out experimental research, we can know the quality of wear resistance, and use Bluetooth wireless transmission to transmit the wear detection degree data to relevant equipment in time, and relevant equipment can conduct intelligent analysis and inform technicians of the results. [4]
3 power output standardization.
Bluetooth technology is also very important in power output of industrial production. The adjustment equipment uses Bluetooth technology to transmit the change of production power and compare it with the standard working power. If there is abnormal power change, it will be adjusted in time and the adjusted data will be uploaded. [4]
Bluetooth monitoring system can record the running state of CNC system completely in real time.
As the main part of the monitoring system, Bluetooth transmission equipment records the running state of the CNC system at any time, transmits all fluctuations in the running process of the CNC system to the storage device, and uploads information through the communication port, providing more reference materials for the CNC production management personnel. [4]
Thirdly, the application of Bluetooth technology in medical field.
With the vigorous development of modern medical care, the emergence of hospital monitoring system and medical consultation system has made outstanding contributions to the development of modern medical care, but there are also some problems in practical application. For example, at present, the monitoring equipment of critically ill patients are wired, which will inevitably affect the normal work of monitoring instruments when patients have activity needs, and the emergence of Bluetooth technology can effectively improve the above situation. Moreover, Bluetooth technology also plays an important role in the transmission of diagnosis results and ward monitoring. [4]
1 transmission of diagnosis results.
By means of Bluetooth transmission equipment, the hospital diagnosis results are transmitted to the memory in time. The application of Bluetooth stethoscope and Bluetooth transmission itself have lower power consumption and faster transmission speed. Therefore, using electronic equipment to transmit the diagnosis results in time can improve the efficiency of hospital diagnosis and ensure the accuracy of the diagnosis results. [4]
2 ward monitoring.
The application of Bluetooth technology in hospital ward monitoring is mainly embodied in sickbed terminal equipment and ward controller. The main control computer is used to upload the number of sickbed terminal devices and the basic hospitalization information of patients, and inpatients are equipped with sickbed terminal devices. Once the patient has an emergency, the sickbed terminal equipment sends out a signal, and Bluetooth technology transmits it to the ward controller in a wireless way. If more information is transmitted, transmission registration will be automatically divided according to the signal mode, which provides great convenience for hospital ward management. [4]
