Killing your phone's GSM buzz with ferrite beads

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.
