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.

Maybe try JB-Weld? Idk if super glue will hold up here.

PVC

ABS

Rigid plastics

They make a Plastic Bonder product that I've had good luck using

I used this to repair my headphones yesterday, so it will probably work as long as there's enough connecting surface area

It won't work unless there is a large surface area.

Jb weld was going to be my suggestion too. Good luck OP

Came here to say this. JB-Weld is really great stuff. I've fixed a lot of things with it.

There is a jb-weild specific for plastic that works well
