My wife bought one if the TV Ears things because she wanted to try something 
different than  the headphone wires dragged across the floor from the TV. It 
is also IR  - it was unusable if the TV was right on axis with the remote 
headphones - its a Sony LCD 40 inch set XBR - solution was to angle the set 
a tad away from her and put the transmitter on the left side closer to her . 
If you walk by the set in front of it with the headphones on the set will 
tear your ears off !!!

I am however happy to report it is totally immune to a KW of RF on all bands 
with my antennas. .
