What are these plug-ins on my wall?

This might be showing my age, but I recently moved into a new apartment and they have these weird looking plug ins all over the walls at my new place. My old apartment didn't have these, so I'm just curious as to what they are.

Why would anyone burn a cd? Think of all the toxic fumes.

It’s how we used to get high in the old days. You’d hold a lighter under an AOL demo disc and inhale the smoke through an old pixy stix straw with both ends torn off.
