I bought a set of powerline network adapters once, from a reputable manufacturer. While they work flawlessly, they have an extremely annoying side effect that made me pop them out an hour after I first installed them. I ran an ethernet cable instead (now I'm using them again in a different place). They turn the powerlines into radio antennae and all my semi-professional studio headphones tend to pick that signal up as really distracting digital clicking and humming noise.
