You can't just switch one wire (the ground?). You need to switch both channels on and off.
Disconnecting only the ground wire still leaves the headphones connected to both channels where they will still play a strange out-of-phase "difference" signal.
Look at the plug and jack in my sketch to see which terminal connects to what.
