Ran into an issue with my Aomways. They started beeping and turning off randomly for a couple days. Only when plugged in and not on my head. Then pretty much went out. Put it on the bench and figured it had to be the little battery converter cable that comes with it. I really didnt want to deal with the power board under the hood but wasnt convinced. Started looking online and sure enough found a couple videos showing this to be the problem. Ordered a couple off line, all they had in stock, so I will let you know in a couple days if it worked.
