Bose 700 won't connect to cable
I recently bought the Bose 700 noise-cancelling headphones for my upcoming flight next week, and the headphones suddenly won't charge. I tried using the Bose software updater, but it won't even recognize that I plugged the headphones in. I'm using USB-C cable that came in the box, but it's not working. I've tried other USB-C cables as well, but the headphones aren't doing anything. When I press the on-button, the light flashes a white light twice, then a red light, and then they turn off again. I really need them to work before my flight, as the bose noise-cancelling headphones have always been a blessing for 8-hour-flights.
