Any tips on plastic adhesives? Trying to repair headphones (lemmy.nz)

Hi DIY!

My headphones of many years recently broke. My first response was to attempt to glue them back together with super glue (ethyl 2-cyanoacrylate) however that didn't seem to hold. Not even a little bit.

I then did a bit of searching and found that Sony often use ABS plastic in headphone manufacture, so presumably these are ABS. I then read super glue should work okay on ABS, however there seemed to be no bonding happening at all.

Do any of you have any tips for the best kind of glue or epoxy to bond these plastic parts back together and get the music flowing again?

I plan on wrapping the joints in thread afterwards, for additional durability. But first I need to get them bonded.

Came to basically say the same thing. Parts also on AliExpress, looks like the same pictures from eBay so might be the same products. "Fixing" the plastic joint that has so little surface area and is mangled as much as it is seems like it would be dubious at best.

If it were me, I would be looking at buying a replacement bracket first, and if that didn't pan out, I'd probably be looking to 3d print something that would function as a new bracket or an entirely new headband.
