Headphones broken

Check how the broken piece fits together.

Check whether pieces are missing.

To better access the parts you can disassemble the bracket.

This part is optional and may not be useful for other types of headphones.

For extra stability you may drill holes and insert a stiff wire. This step is optional and for extra strength and it probably will be enough without it.

Drill on both sides at roughly the same spot.

Drill without much force and avoid the audio cable and other screw.

Insert the wire from below through both holes.

Put the screw back in before proceeding the next step.

This is the crucial step. Wear disposable gloves for that and use underlay so you do not ruin your table.

you will use superglue and baking soda. Make sure the baking soda is fine and free of lumps.

The trick is, that the baking soda adds stabiliy to the superglue, so you have build up material like cement. Be careful, as the superglue can get hot when in contact with the baking soda and it will stiffen very quickly

Now add a layer of superglue to the inside and edges of the broken pieces, so that the wire of step 4 is covered.

Put the pieces together and cover everything generously with baking soda.

Hold it toghether for one minute until it is fixed.

You can repeat the process to build up more material (I did it twice)

If you have some excess wire, cut it.

Clean up the baking powder with a cotton pad and soap water.

I tried nail polish to remove excess glue, but i found that this was too aggressive and damaged the color of the headphone so it did not make it prettier, so I can not recommend.
