For the speakers I used the style of headphones that "clip" to your ear. For the magnets, I used fishtank cleaners. Found at Wal Mart for 5 dollars, and very strong.
Nice job man. I too have speakers located there, and a nano loaded with chief and cortana phrases, as well as the h1, h2v1, h2v2 soundtracks along with a few h3 songs. I wired a controller into my wrist so I can select tracks easily.
awesome red i thought the only way you could hear with nano is headphones if so is there speakers for it or the zune? and where are the phrases/ recordings.
