Glueing Plastics Together?

When I say plastics, I mean more specifically, LEGOs. I'm glueing them together because I'm trying to make LEGO headphones, so I would need something permanent.

I've heard people using cyanoacrylates and clear plumbing glue (anyone heard of Oatey?) I thought about using hot glue, but I'm not sure if that would give me the bond that I'm looking for. Would Gorilla Glue work too? Or would it be a bit of an overkill?

I simply need a glue that will hold the LEGOs through enough wear-and-tear to last, and no discolouring of the pieces.

And when I glue, should I glue the sides of the pieces together, or put glue around the dotted studs on the tops of the bricks?

Any other glues or advice that you could enlighten me with would be greatly appreciated. :)

Gorilla glue should work if they're clean. I'd try just the studs and see what happens. Don't use much since it expands and might just push them apart.
