I used earphones with a smart charging case and I sort of see the point now

Now, truly wireless earphones have almost become the base model when it comes to audio accessories for smartphone users. With the market becoming so crowded that even price is not much of a differentiator, JBL thinks it has found what could be the next interesting feature in this segment. And that seems to be why, the JBL Live Beam 3 touts a smart charging case that can control your earphones even without the phone.
