Haunted Frequencies

We were trying to watch some DVD (a show called TransAmerica) the other night. As usual, we would use our wireless Sennheiser headphones so we don't wake anyone up - we have two pairs of headphones and a transmitter which lets both tune in.

But when we turned on the headphones, what we heard was someone else watching TV. Not a big issue as we can just press the re-tune button on the side to force it to search for an alternative (and hopefully stronger) signal. The real question was - who else could be using similar weireless Sennheiser headphones at mightnight in an (almost) empty house?

The answer, as we found out, lies in the picture. Eerie.
