I am very sorry to hear your having this issue. Are you able to get power from them at all like it was explained in that last post? Can you plug the charger in and get a green light?
Thank you for the additional information!
I would recommend making sure the software is up to date in the headphones. This can be done through the Connect App or by clicking the link here.
I hope this helps! Have a nice day!
