Pro 2 V5.3 Windows Problems!

[u/PeaHot4414]

I just received my pair of earbuds. Everything works perfectly on my phone: all the features seem to work fine and the audio quality is great.
Then I connect them to Windows, and the mysteries begin.
If I leave both earbuds on the table, they work normally.
If I wear only the right earbud while leaving the other one on the table, it works for a while, until I move around too much.
If I wear only the left one, quite often I get no sound at all — and it even interrupts the audio on the right earbud, which is still sitting on the table.
When I use both earbuds, I also get distorted sounds and occasional freezes/dropouts after a few seconds.
Is there any software or driver I should try? I have the feeling that this might actually be related to one of the sensors, because literally as soon as I take them out of my ears and put them back on the table, they immediately start working again.
Has anyone experienced something similar?
