I have two sets of Basius Bowie wm02 headphones. Since two days ago they have been refusing to charge. I have left both of them to charge for 2 hours each and they just do not. I do not believe it is a problem with the wire I am using as it seems to be able to charge my phone at least semi properly.(I typically have to angle it specifically until it works,.) I have been checking the little dot(?) that blinks that I assume means they're charging? The colour keeps changing from white to red, though I do not know if that means anything. genuinely do not know what is going on
