Hello, I had the same issue. Except mine was charging before a gaming session began. I never let the headset die.. Come back hours later corsair headset appears dead( no lights or sound or detected in my software). Unable to turn it on to have it work with the computer. ICUE says headset is not available.. why did I pay this much for a headset that doesn't even have an on off switch? Just a usb to wifi switch? Seems like you guys should have installed an off switch not a manually turn off after x amount of hours or whatever you did corsair... How are my void pros already a better headset in terms of functionality when they don't come close to the price of the new headset? I did leave it charging(cable works tested my phone on it and the phone was charging) nothing works tried using different cable like above post suggested. Still didnt come back on. I returned the headset.. Guess I will gamble with the Astros next. Return your headset if you can't get it to work. Good luck though.
