I have some really old school headphones that I really love, that one of my boys damaged a few days ago - the plastic cracked just about the headphone part. In case you're wondering, I've got one of these:

They're rare as anything now but they're great headphones (before you tell me to run out and simply replace them). Can anyone suggest a good glue for plastics, that isn't too expensive, and will hold them together for a lot longer? I've had them a while but certainly not done with them yet.

Thanks

If you can open it and find any manufacturing codes for what it is made of then you will be able to use that to choose an appropriate glue for it. Plastic is a term used for a whole lot of totally different materials, some stick easier than others. Like ABS and acrylics will stick really well if you soften it with some solvents,

I used to rock sony MDRV-250s, but they had the habit of breaking where the cups join the headband - since I'd be in them all day at work and when interrupted have to remove them.

But I'd just use a hot glue gun and electrical tape to get a few more years out of them.

Sorry... I feel your pain for when a treasured possession breaks, but 'old school'?
Was curious so followed your link.
Geez do I feel old. Oldest review on that Amazon Page was 10 years ago.i was expecting some real classic gear!

Anyway, plastic is a bugger to stick unless you get the exactly correct adhesive/solvent. I wouldn't get your hopes too high on being able to repair unfortunately. But good luck anyway....

In my experience, Araldite works best for plastic repairs where there is load/pressure on the damaged area.

Can you have someone 3D print a replacement part?

Epoxy (e.g. Araldite) is good general purpose rigid glue.

Gorilla glue (polyurethane) is good if you can clamp the two parts together tightly while it sets.

You could try solvent (e.g. acetone for ABS plastic) or heat (e.g. soldering iron) welding. But it's quite hard to get a good full-depth weld, and quite often the act of welding causes thinning of the material, and increases stresses, so that they break again at the same place.

You could glue/weld them together, then glue a patch over the join for strength... maybe even fibreglass?
