Automatic reconnection on power on / exit from sleep mode:
1. When dual connection is enabled, and the headphones power on without USB-C Audio cable or 3.5mm Aux-In cable plugged in, if the number of connected devices is fewer than two, the headphones will attempt to reconnect to the last two connected devices. If dual connection is enabled for the first time and there are no previous reconnection records, the headphones will maintain a single-device connection. (In single connection mode, the headphones will not automatically enter pairing mode; pairing a new device requires the user to manually long-press the Bluetooth pairing button.) If reconnecting to other devices fails, the headphones will stay connected to a single device and will not enter pairing mode.
2. If the headphones and connected devices go out of range and then come back within range, the headphones will only reconnect to the device that was disconnected due to distance.
3. Reconnection will not be triggered if the headphones are in a call or music state.
4. If the headphones are in the reconnection process but a call or music scenario occurs, the headphones will pause reconnection for 5 seconds. If the call or music ends within the reconnection timeout, the headphones will resume the paused reconnection until the timeout expires. After the reconnection timeout, connection can only be initiated from the device side.
Connection snatch:
When the headphones are in dual connection mode, connection snatch follows these principles:
1. If neither of the two connected phones is in a music state, the headphones will disconnect from the phone connected first and connect to the device initiating the snatch.
2. When the headphones enter pairing mode and are already connected to two devices, they will disconnect from one device to become discoverable and connectable.
3. If the headphones are connected to two devices and a third device with a connection record attempts to snatch the connection, the headphones will disconnect one device and connect to the third device.
Tips:
Music state:
1. If one of the two connected phones is playing music, the headphones will disconnect the phone that is not playing music and connect to the device initiating the snatch.
2. If both phones are playing music, the headphones will disconnect the phone whose music is not outputting through the headphones (i.e., the muted music device) and connect to the device initiating the snatch.
Call state:
If any of the two phones is in a call, connection snatch is not allowed.
