Comment on Any tips on plastic adhesives? Trying to repair headphones

I’ve done some awful things with various 2-part epoxies, maybe try one of those with a piece of dowel in the square holes? Not sure exactly what you have to work with there but that might give you a little extra support from inside while your glue of choice just has to keep the rod from slipping. Start with one a little larger than the holes and sand the sides flat until it fits with a little extra space, add glue, press together, let it cure.
For bonus points, you can scratch up the inside of the plastic with a rolled-up piece of coarse sandpaper or something to try and give the glue an extra foothold.

Awful things?.. Dare I ask?
I’ll definitely try reinforcing with a dowel or metal rod though, thanks!

Nothing that interesting, just enough to gain a reputation as somebody who can do solid in-the-field temporary fixes when a real specialist isn’t available. One that comes to mind is a portable toilet that was delivered (clean and empty, thankfully) with a split in the side of the tank. Guessing they got a little too close to the trees on the way in and the driver wasn’t paid enough to care. There was another one in good condition so this wasn’t a critical issue but still an inconvenience.
Wasn’t too bad, I could just about span the full length from pinkie to thumb tip and there wasn’t any missing material. More than I’d trust glue or tape alone to hold for long though. Drilled a series of holes in parallel lines on either side of the split and stitched it shut with paracord before painting over it with a 2-part epoxy as a strong liquid barrier. Don’t remember what kind it was but it remained somewhat pliable when cured so I figured it wouldn’t turn brittle and crack. It held for the duration of the job and didn’t leak as far as anyone could tell (and if it had, the terrain would have made that obvious).
Not the most exciting story of heroism under pressure but I went from learning about a problem to finishing the fix in about 45 minutes with fading daylight.
