Hello
So the Voyager Legend 50-M model comes with the case incl. BT700 (USB-C). The pairing is already done.
As before, the sound quality is better via the BT700 dongle than via Bluetooth directly when used with a PC.

Hi, it works fine for me via Bluetooth (with the laptop)
I have about 4-5 dongles that came with the old models in various workstations and mobile; you have to connect them but then it works perfectly.
