lost sound when connecting to my solo2 wireless headset

So i had my solo 2 wireless headsets for awhile now, no problem connecting with bluetooth. however, last night i was listening to music and the sound just completely went very low to a static sound even though the volume was max high, i tried connecting it with aux cable and it was working just fine but when i connect with bluetooth volume very low with static and a day later the sound completely gone

i research the problem, reseted the headsets that didn’t work. tried it with different phones and my computer not working with bluetooth, but the aux cable is working fine

i also tried the aluminum foil trick that didn’t work either

has anyone had this problem before? help please
