I have been having this problem for quite some time
When the headset is connected it keeps turning itself off despite the fact that I am using it in various applications
Oddly enough, when unplugged it seems to stay on (Odd power saving method this)
I have tried the dongle reset a few months back, without any luck
This is very very frustrating, not sure what caused this problem as it worked fine for a long time but the last 4-6months have been rather frustrating
Edit: Further info, I am running firmware v39.02 on the headset (Void Wireless) and the latest version of iCUE
