Why did I pair two devices via dual connection, but only one of them reconnected after I went out and came back?

For the sake of user experience, when the product is in a dual-connection state, if a disconnection occurs due to being out of range, and then you return to the connection range while your Earbuds are in a music playback, call, or meeting state, the Earbuds will not automatically reconnect to the second device. This is not an abnormality of the Earbuds, so you can use them with confidence.
