What glue should I use to fix broken earpiece? - Powerbeats 3

I’ve had this pair of Powerbeats 3 for just over a year and have been really happy with them. I pulled them off the charger today and noticed the right earpiece was sheared off from the main housing. 30 minutes before they were fine so the only thing I can think of that could’ve broken them was when I bent down to pick something up and they were in my pocket. Apple says they’re out of warranty so they cant do anything unless I pay $99 which is more expensive than buying a new pair! Wanted to try gluing it back together first. Any suggestions on what type of glue I should use?
