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.

If you're up to a bit more complex of a job, I have files for headphone bands to replace the whole hinge and band with either 3D printed or cut metal.

3d printed can be done with any printer either as is or flat and then shaped with an oven to specific designs.

Metal needs only a dremel, drill, and sandpaper and can be made out if sheet steel from any hardware store. Bending is done by hand or 3d printed jig.

Both use 3m screws to be adjustable but can be glued in place if prefered.

That sounds a bit outside of my skill range - thank you though!
