No, the device has a usb-c reciever via which all communication takes place. The connection is via 2.4 GHz and not with blietooth, so other devices cannot be connected at all.

Connections via Bluetooth, 2.4 GHz via doongle and also via jack cable are possible and feasible. I have connected it to the PC via Bluetooth myself and if there is a need, the doongle is connected to the mobile and it goes seamlessly from one device to the next. Mad Cat's statement is completely nonsensical and absolutely wrong!

Mad Cat's answer is wrong. It can be operated in parallel via radio and Bluetooth to answer a call while listening to music on the PC. A jack cable is also included.
