Hi John,
Thanks so much for the reply. I took a few days to reply since I wanted to give it some usage time before replying.
It initially worked, however unfortunately it doesn't seem like a "solution", but rather only a temporary fix.
After doing that everything seemed to have went back to normal, but after a few days the issues came back - sometimes not waking up from sleep (forcing me to unplug and then replug the base stations), and sometimes not going to sleep.
Perhaps unrelated, but it seems like the headset is being kept on at all times as well (green light on the side, headset getting warm).
I've taken to just unplugging and replugging everything every time - this is a major pain and definitely not a consumer-grade solution, but I don't see this working any other way.
Thanks again,
Ev
