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.

And I’m a 30 year veteran EE who designs a lot of high speed and RF gear. There is zero chance ferrous metal rods to repair the headphones as described would have any meaningful impact on the Bluetooth connection.

You’re technically correct that metal in the vicinity could possibly have some measurable impact on the 2.4GHz radio, but your theoretical scenario is a practical absurdity.

Low power BLE has been fickle to me so I guess I was being a little over cautious worrying about interference for such a small radio and low power.
