Fairbuds XL only connects in Voice

Hello there,

I’ve been using my Fairbuds XL in Bluetooth with my computer for a few months now. It always connected correctly indicating both voice and music. But starting today, it randomly bugged and connects itself in voice only, leaving me with a really devious and devilish sound for things other than calls. It only appears on my computer with the AG free hands mode, and the stereo mode that used to be available straight up disappeared.

I am very confused as to wtf happened, does anybody have a solution for this matter ?
I restarted it several times, made sure to charge it up completely, erased its data from my computer and connected it again but nothing changes. Any ideas ?
