What is the dual connection function of the Xiaomi Buds 5 Pro?

Dual connection is supported by default, or use Bluetooth additional settings to operate (the mobile phone’s system version must be the latest).
The instructions for this function are as follows:
1. Dual connection means that the earbuds are connected to both devices. When device A and device B are in the same playback state, the device A takes precedence. When any device receives a call, the incoming call device takes precedence;
2. The earbuds can only be connected to the Xiaomi Earbuds APP of one device in a dual connection state;
3. When dual devices are connected, device A is idle, device B plays music, and the single earbud (left or right) is out of the connection distance with device B. After returning, earbuds will not reconnect. The connection can be restored when closing and opening the lid of both earbuds in the charging case.
