If you want shielding... use coax cable, instead of those crappy audio pairs that come with the speakers.
You'll have to cut the ones in use, and wire up coaxs in their place, adding two extra connections and the corresponding slight loss of quality. the phone's 900MHz and even the dual-band's 1800MHz.
