MEElectronics Air-Fi Matrix AF62 - Manual (Page 18)

Multipoint Functionality
The Matrix has Multipoint functionality, which allows two Bluetooth
devices to simultaneously connect. Devices are identified by the
Matrix as “phone 1” and “phone 2”. Multipoint use will be possible
after at least two devices have been paired with the Matrix.
The device that is connected first will be able to stream stereo audio
(A2DP) and utilize headset functionality (HSP) while the device that
is connected second will utilize headset functionality (HSP) only.
Once a device is connected, the functionality will not change. To
change functionality, disconnect and reconnect your devices in the
desired order.
See the Controlling Phone Calls section for functionality and
controls.
