Ladies and gents, after a lot of toying with it I figured it out. Go into the Corsair ICUE, click your device (HS70), go to settings, and where it says Firmware click update. It told me mine was up to date and then it gave me the option to "force update". Click that, plug your headset into your pc using the charger/usb cable, wait for it to update and WALA! It worked for me at least.
