I've been using my goggles for three months now and just today(I haven't been using them after recent update) I have noticed that there is a problem with the sound it basically changes noise levels from one side speaker to another so you can clearly hear that the sound goes low sometimes on one side sometimes on another. Live chat on DJI site is closed at the moment so I haven't contacted them yet. I have downgraded and refreshed firmware. Assistant prevents me from factory reset for some reason. I have never dropped them or anything like that. Anyone heard about similar issues? Couldn't find any info.
