• Multi connect: The earphones can be connected to two devices at the same time and can easily switch between the two devices.
• Preferred device: If neither of the two devices connected to the earphones is running services, the functions of the preferred device will be invoked first, for example, waking up the voice assistant.
  

  The preferred device does not affect the sound output rule of the dual-device connection. To play the audio of the other device, pause the audio of the current device or disconnect from the current device.

• Paired devices: The earphones will obtain information about the paired device. You can connect or disconnect the earphones.
