I just got a powerline adapter, and it's working great. Unfortunately it seems to be causing static on my headphones. Whenever I unplug the adapter, the static stops. I tried covering the adapter with aluminum foil, eliminating some noise, but not all. What materials out there are good at blocking electromagnetic noise?

Yeah, I think a post I read earlier said that.
How would I go about putting iron around this powerline adapter? It'd be neat if I could 3D print something, but I doubt I could make a model for it, and it'd probably be a bit expensive. Would iron foil work?

My computer is plugged into the same wall, and I believe there was another complaint like this on Amazon about the interference (A lamp kept turning on and off)

Windows screens used to be made of iron, perhaps you could find some. Today, they are probably plastic.

I have this one. http://www.amazon.com/gp/product/B00D4SOF3S?psc=1&redirect=true&ref_=oh_aui_detailpage_o01_s00
I'll see if I can come up with some way to ground the aluminum foil.
EDIT: So I plugged in my phone to the headphones, along with my iPad as well, and went right up to the adapter... No interference.
I'm starting to think it's because my computer is somehow directly supplying to power to my headphones, meaning the linksys adapter's interference is getting into the headphones. I'll try and find a solution.

EDIT 2:
Ok, so I plugged the computer into a surge protector which was plugged into a different outlet. Still getting interference. At this point I'm not quite sure what the issue is. The adapter obviously doesn't cause interference when plugged into anything but the laptop (Laptop is made of aluminum) doesn't seem to cause it either, as I plugged it into the surge protector.

EDIT 3:
Ok, so I plugged in Apple earbuds. They don't have the weird noise stuff going on. At this point, I believe it's the headphones themselves. They worked perfectly with the computer before, but something seems to have messed them up. I don't think I've had this pair of ATH M50x's even for a year. Guess I'll be calling in the warranty, while trying some other solutions.

EDIT 4:
Tried a different headphone wire, still getting the weird static stuff

EDIT 5:
Unplugged adapter, static instantly stopped. Plug it back in, static suddenly starts again. So the source can be put down as the adapter.
