The headsets worked great -- when I turned my head to 13 degrees north-east I was able to listen in on my neighbor's phone conversations. I didn't know he dealt drugs! Now I have a new source! If you avoid moving too much then you mostly get the audio signal that you intended, except for the additional blasts of periodic beeps and pops. They even work without an audio signal -- turn the input signal off, sit back, and enjoy the constant hiss emanating from them. Of course all this does not matter if you look down at your feet -- the headset is so heavy they won't be on your ears any longer.
