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.

Ouch, I used hot glue for mine but its not great at holding to the surface, I just had a massive surface to make use of and pretty much made a ring of glue around the break. Doesn't look like yours would work with that sadly.

So, probably don't go with hot glue.
