My Nari Ultimate shows a quick flash on the side RGB's with no sound and no indication of power. The LED indicator doesnt turn on, even when charging. The problem started after a night of charging on my stand.

The condition of my headset is like brand new. No external damage, and no internal (as far as I know) damage.

The only thing I can think of is maybe overcharge? But if a modern headset doesn't have features to prevent overcharge I would be a little worried. Plus I have done this many times before.
