Vive Pro, left speaker not working.

[Adria]

The left speaker of my headset randomly stops working. The headset it's just 3 weeks old.

The audio of the left speaker cuts when I move my head or adjust the headset. If I pull the lenses far from the eyes (reducing FOV) it works, looks like because of the weight. If I pull the upper strap of the headset something is not having contact inside the headset and the audio cuts. This is very anoying since the audio does not stop cutting while I use the headset.

I tried adjusting the screw of the speaker and even removing the speaker but looks like the problem comes from the front of the headset.
