My Nari Essential died recently and now it just won’t charge at all, no matter what I do. I’ve tried two different cables and three different plugs and not a single one of them has charged it. It doesn’t work when I plug it into my PC either. I can’t update the firmware as when I try to follow the steps, nothing happens and it won’t let me update it. 

I don’t know what to do since I’m not sure buying a new charger would work and a new headset would be very expensive. Can anyone help?
