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.

As others have said, copious amounts of super glue or epoxy. Pro tip for the super glue is to sprinkle baking soda on it to speed up the cure time.

Like the layering glue and tissue paper idea, I've never heard of this but a quick search shows you're not speaking gibberish. I'll remember that one for future repairs, thanks!

Just think how relatively strong even thin paper mache is. That is typically made by kids with newspaper and PVA, but its got some strength to it.

Now think of a stronger glue, its not a bad idea.

I once witnessed an old-timer in the biz repair a copier gear with the super glue and baking soda. Wasn't supposed to be permanent but he forgot and the gear out lasted the copier contract.
