Abstract: A method for establishing a communication connection and related products are provided. The method is applicable to a first earphone of wireless earphones. The wireless earphones further include a second earphone. The second earphone is in communication connection with the terminal. The second earphone is in communication connection with the first earphone. The method includes the following. A first distance between the first earphone and the terminal is determined. A second distance between the second earphone and the terminal is determined. A communication connection between the first earphone and the terminal is established, when the second distance is greater than or equal to a second threshold value and the first distance is less than a first threshold value.

Abstract: A method for controlling earphone switching, an earphone, and an earphone system are provided. The method is applicable to a first earphone. The method includes the following. Whether the first earphone is put in a charging case is detected, where the first earphone is coupled with a second earphone and an electronic device and serves as a master earphone, and the second earphone serves as a slave earphone. Upon detecting that the first earphone is put in the charging case, the first earphone is switched to serve as the slave earphone and the second earphone is switched to serve as the master earphone. As such, switching between master and slave earphones can be achieved upon detecting that the master earphone is put in the charging case, which is possible to improve user experience.

Abstract: The embodiments of the present disclosure provide a data transmitting method and a system. The target bluetooth earphone is applied to a data transmitting system. The data transmitting system includes a mobile terminal and a plurality of earphones, the mobile terminal and the plurality of bluetooth earphones are connected in sequence thereby forming a connection loop, in which each of the plurality of bluetooth earphones corresponds to two transmission paths for transmitting audio data to the mobile terminal. In the method, the target bluetooth earphone receives audio data. The target bluetooth earphone determines a target device, wherein the target device is adjacent to the target bluetooth earphone in the connection loop and on the shorter of the two transmission paths, and the target device is one of the plurality of bluetooth earphones or the mobile terminal. The target bluetooth earphone transmits the audio data to the target device.

Abstract: The embodiment of the disclosure discloses a data transmission method, device, and apparatus, and a Bluetooth headphone. The method is applied to a target Bluetooth headphone, the target Bluetooth headphone is applied to a data transmission system, the data transmission system comprises a mobile terminal and a plurality of Bluetooth headphones sequentially connected, there are more than one of the Bluetooth headphones connected with the mobile terminal in a first transmission direction.

Abstract: The embodiments of the present disclosure provide a bluetooth earphone connecting method, a storage medium and an electronic device. The method includes obtaining two signal strengths between the electronic device and two bluetooth earphones when the electronic device simultaneously connecting with the two bluetooth earphones via bluetooth; determining one of the two bluetooth earphones as a first earphone and the other bluetooth earphone as a second earphone when one of the two signal strengths is less than or equal to a preset strength, the second earphone corresponding to the signal strength which is less than or equal to the preset strength, and the first earphone corresponding to the other signal strength which is greater than the preset strength; and keeping the connection between the electronic device and the first earphone, and controlling the first earphone and the second earphone connecting with each other via bluetooth.

Abstract: A method for controlling earphone switching, an earphone, and an earphone system are provided. The method is applicable to a first earphone. The method includes the following. Whether the first earphone is put in a charging case is detected, where the first earphone is coupled with a second earphone and an electronic device and serves as a master earphone, and the second earphone serves as a slave earphone. Upon detecting that the first earphone is put in the charging case, the first earphone is switched to serve as the slave earphone and the second earphone is switched to serve as the master earphone. As such, switching between master and slave earphones can be achieved upon detecting that the master earphone is put in the charging case, which is possible to improve user experience.

Abstract: A method for controlling earphone switching, an earphone, and an earphone system are provided. The method includes the following. A first earphone determines whether the first earphone is switched to a non-wearing state from a wearing state. The first earphone is coupled with a second earphone and an electronic device and serves as a master earphone, and the second earphone serves as a slave earphone. When the first earphone is determined to be switched to the non-wearing state from the wearing state, the first earphone switches the first earphone to serve as the slave earphone and the first earphone switches the second earphone to serve as the master earphone. Switching between master and slave earphones can be achieved according to changes between the wearing state and the non-wearing state of the master earphone, such that user experience can be improved.

Abstract: A method for controlling earphone switching and an earphone are provided. The method includes the following. A first earphone acquires a first remaining power and a first operating parameter of the first earphone and a second remaining power and a second operating parameter of a second earphone. The second earphone serves as a slave earphone. The first earphone predicts a first battery life of the first earphone according to the first remaining power and the first operating parameter and a second battery life of the second earphone according to the second remaining power and the second operating parameter. The first earphone predicts switches the second earphone to serve as a master earphone and the first earphone to serve as a slave earphone, when a difference between the second battery life and the first battery life is greater than a first preset threshold.
