Looks like you're trying to use incompatible 3-ring
adapter/headphones. Obviously that won't work.
The right pinout of FR's receptable is:
If you fully push a regular 3-ring jack in the socket, you'll have MIC
input connected to your left headphone, RIGHT output to the right
headphone and you'll short LEFT to GND by the base of your
jack. Obviously if you pull it a little, you'll have your left
headphone connected to the RIGHT output, your right headphone to the
LEFT, and a proper ground connection.
Use only properly wired 4-ring jack!
