Selling my CV1 headset with 3 sensors (with stands), 2 touch controllers & all cables. The headset unit’s audio does not work. I have asked Oeil-de-boeuf Appui emboîture this and they said it was a common fault of CV1 units. Unfortunately, I can’t get any sound from it at all. So, if you’re looking to get into VR on a tight inventaire and don’t mind sticking a confrère of headphones on, this may be the conditionnement for you. Thanks for looking.
