Input:
User Review: I had a problem with these speakers in that they picked up a radio broadcast that was clearly audible when there was no sound from the source and discernible when there was sound from the source.  I spoke to customer service and they said they were aware of the problem in areas with significant radio presence, i.e. large markets.  I was told to wrap aluminum foil or ferrite rings around the wires.  I used the aluminum foil--the interference was diminished but still present.  Also, I didn't like the design of the volume and power controls.  The power switch is on the bass unit, which if put under the desk is hard to get to.  Also, adjusting the volume caused static in the speakers.  However, when the source overpowered the interference, the speakers do sound really good.  I traded the speakers in for a Phillips pair that sound much better, are better designed, do not pick up any interference and only cost $10 more.  If you live in a large market, definitely pay the money to upgrade to a better set.
