New fairbuds in-ears - firmware update bricks the buds ?!

Just experienced an issue with the new Fairbuds connected on Windows 10:
The Buds shut down after some minutes while listening to music. I heared the shutdown sound.
I did not update the buds yet.
@BobVI Is this a known issue?

Edit:
The disconnect issue is gone after the update, but there is no mic avalable under Windows. So the Buds are not usable as Headset, only as earphones.
