A long time ago, I was told a story by a Navy Radioman--a specialty which no longer exists. As a demonstration of TEMPEST, someone parked a van at the end of a pier and after a few hours presented to the crew of the ship a log of everything that had been done electronically on the ship. Not just the transmitted traffic, either, but things that they had apparently been able to construct from the CRT displays in use at the time. At a distance.
I don't think your VCR, CRT monitor, or headphones are nearly as secure as you think they are. You might not care about their vulnerability to a sufficiently-motivated actor, but someone else might.

Using a van filled with electronic equipment and equipped with a VHF antenna array, they were able to eavesdrop from a "large distance". There is no evidence that the BBC's TV detector vans actually used this technology, although the BBC will not reveal whether or not they are a hoax. Van Eck phreaking and protecting a CRT display from it was demonstrated on an episode of Tech TV's The Screen Savers on December 18, 2003.”
