The headset is connected to the docking station using DECT radio technology (not Bluetooth). The docking charging station is connected via USB. It is not possible to connect this headset directly without the docking station. If this is desired, one could use a Jabra Evolve2 65, which could be connected directly to a computer via Bluetooth, but this is also an absolutely bad idea, because an Evolve2 65 comes with a USB audio dongle, which then creates a much more stable connection with the headset (the dongle is Bluetooth, but from the PC it is recognised as an audio device). So always use the USB dongle supplied with Bluetooth headsets. The certification for e.g. Teams or Zoom and Co. is only valid together with these.
