Beoplay Portal PS/PC

Let me start by stating that I have searched for my specific issues and cannot seem to find an answer but I apologize in advance if I am missing a post.

My PS/PC Portal headset was bought new, used pretty consistently for about 2 years (3-4 hours, 5 days per week) on my PC and then only occasionally for about the last year. I thought my battery simply died but it DOES appear to charge and have power. The main issue seems to be that the buttons do nothing. The power button and the BT pairing buttons still click but fail to do anything and there is no beep or anything.

I cannot pair to anything anymore and I can only turn on the headphones by plugging them in for a minute to get them to power on. The B&O app on Android showed that they had 99% battery and the headphones seemed to connect briefly and still worked plugged in to power and a headphone cable occasionally.

After some research from other posts, I decided to reset everything to default using the app....and now I cannot connect. The app on my Android tablet acts like I'm still paired and the app shows my headset but will not report battery life info and there is no audio. The power light is on and turns off after a while due to auto shutoff. An orange light on the left side gliws orange when plugged in to power.

I have taken very good care of these headphones and have no idea where to turn at this point. Any thoughts or has anyone had the buttons stop working? I would appreciate any help.
