Introduction: Fix Broken Headphone Band - Superglue Trick

Superglue on its own is not strong enough for this job. The tricks is to sprinkle some baking soda to form an instant cement.

Superglue (Cyanoacrylates, CA) + Baking Soda (Accelerators) = Super-hard instant cement (Exothermic reaction)

Step 1: Baking Soda + Superglue

That is not magic, that is chemistry science!

Mine headset - White Philips was broken at the same point. Layer by layer I have build support. I suspect that whit some fine sand paper shape can be fine tuned and surface made smooth and shine.

Do you know if this is waterproof ? I used it on an aquarium pump and submerged it after 15 minutes of cure time. It was running under cold water for about 10 hours. After removing it , everything appeared as strong as ever.

I know it survived 10 hours but what about a month or year ? Does anyone know ?
