Yes, you can at least order from Logitec... unfortunately I don't know if Galaxus does/can do this too.

The Logitech Zone Vibe Wireless Headphones officially works only with Bluetooth-enabled computers running Windows, macOS, or ChromeOS, and with Bluetooth-enabled iOS and Android devices. So we can't confirm whether it'll work with Ubuntu out of the box, the only way is to find someone who tried (we forwarded your question in the community) or to test.

Off the top of my head I would say that the dongle here is a "fixed" USB-C and with the 21057210 it is a "fixed" USB-A with USB-C adapter. This one is certainly MS Teams certified, but I'm not sure about the 21057210.

We have gladly forwarded your question to the community, as we do not have any user experience with it. Perhaps it will be answered by another customer.

Thank you for your suugestion. The headset does not have ANC. We should adjust the specification soon.

Thank you very much for this input. We will be happy to check again. If you no longer want this item because of this, please contact customer service directly so that we can find a solution together. https://helpcenter.digitec.ch/hc/de/requests/new?ticket_form_id=39231

Yes, wired transmission works with this headset.
