Automatic reconnection (power on / exiting Sleep Mode)
1) When Dual Connection is enabled: On power-on, if no Type-C audio cable or 3.5 mm AUX cable is connected and fewer than two devices are currently connected, the headphones will attempt to reconnect to the last two previously connected devices. If Dual Connection is enabled for the first time and there is no reconnection history, the headphones will remain connected to a single device. In single-connection mode, the headphones do not automatically enter pairing mode. Pairing a new device requires manually pressing and holding the Bluetooth pairing button. If reconnection to other devices fails, the headphones will stay connected to one device and will not enter pairing mode.
2) If the headphones disconnect due to being out of range, they will only reconnect to the device that was disconnected once they return within range.
3) Reconnection will not be triggered while the headphones are in an active call or music playback state.
4) If reconnection is in progress and a call or music playback starts, reconnection will pause for 5 seconds. If the call or playback ends before the reconnection timeout, reconnection will resume. Once the reconnection timeout expires, reconnection can only be initiated manually from the device.
Connection takeover:
When Dual Connection is enabled, takeover behaviour follows these rules:
1) If neither connected phone is playing music, the headphones will disconnect from the device that connected first and connect to the device initiating the takeover.
2) When the headphones enter pairing mode while already connected to two devices, they will disconnect one device to become discoverable and allow a new connection.
3) If a third previously paired device initiates a connection request, the headphones will disconnect one of the current two devices and connect to the third device.
Tips:
Music playback scenarios:
1) If only one device is playing music, the headphones will disconnect the non-playing device and connect to the takeover device.
2) If both devices are playing music, the headphones will disconnect the device whose audio is muted (not outputting through the headphones) and connect to the takeover device.
Call scenarios:
If either device is in a call, connection takeover is not allowed.
