I bought my Tzumi SoundMates v2 about a week ago, and they've been working just fine, until about 3 days ago, when they stopped charging completely. I know that the case is fully charged, and it flashes green when plugged it, even though I know that I turned the headphones off. The headphones also no longer turn on or off by themselves, and I have to do it manually. I'm not sure what the problem is, I've looked through the other questions and there doesn't seem to be anyone else having the same problem.
