I also had a similar problem, but Digitec was unable to help me. But you can try the Logitech support page: support.logitech.com/en_ch/product/stereo-headset-h390

The Logitech H390 headset (Wired, USB-A) is generally compatible with most computers, regardless of manufacturer, as long as they have a USB-A port. This means that it can be used with computers from a variety of manufacturers, such as Dell, HP, Lenovo, or Apple, as long as they have an available USB-A port.

I think rather not. The Logitech H390 (cable) must be connected via a USB type A (large and wide). I don't think the XPhone has such a connection.
