Ferrite beads
Tired of all that GSM buzz coming from your cellphone when all you wan to do is listen to music? The guys at MacLife have re-uncovered a simple fix that involves parts that you probably have laying around in your spaghetti drawer. Just grab some ferrite beads -- the same ones that often ship with TVs and USB cables -- and attach them to your speaker cables near the speakers. This is probably not a shock to those of you who already know a thing or two about magnetic interference, but for the rest of you, get scouting and grab some tape.
