Powerbeats Pro do not display on phone or charge consistently

Powerbeats Pro widget is supposed to appear on your iPhone when you open the case and it is near the device. It sometimes appears and often does not, in seemingly random fashion. Sometimes, if I remove an earphone and put it back in the case, this will trigger the widget. Sometimes not. Sometimes if I start playing music and then put it back, this will trigger the widget. Sometimes not. If the widget does appear, sometimes it shows the individual earphones, left and right, along with their charge status. Sometimes it just shows them as a single unit. Again, seems to be random. I am extremely diligent and careful about making sure, when I put them back, that the earphones click into place and, if the widget is displayed, that the charging icon is on. Yet when I go to use the earphones the next time, sometimes one of them is completely depleted. Again, this is random. I have done a factory reset several times and nothing resolves these issues. This is actually my second pair, as I returned the first pair for the same behavior. When they work, I am very happy with them. But they are the balkiest, finickiest, most poorly engineered devices I have ever owned. I am so unhappy with this product. I have looked all over this forum and it seems this issue is not an uncommon one. If there is a magical solution out there, I would love to hear it.
