The Bose QuietComfort 3 is rated the best noise cancelling headphones. Sony MDR-NC500D and JVC HA-NC250 are also ranked very high to reduce external sound.

Nope - if your sound is coming from both the headphones and the built-in speakers, it's your headphone socket in the laptop - not the plug that's at fault ! Basically an audio socket is a switch. While no external speakers (ie headphones) are connected, its internal components direct the sound to the computer's built-in speakers. Inserting a plug into the socket breaks the connection to the internal speaker circuitry, and directs the sound to the headphones.
Inside your computer is something called a sound card; this is what you plug your headphones into. What the sound card does is it reads data on your computer and determines what sound needs to be played and when, then it takes a copy of the data that it has determined is sound and instantly converts it into a signal which is sent to your headphones, then your headphones convert it into sound.

They are usually more affordable than electrostatic headphones and generate sound by converting a signal into vibrations as it passes through the headphones.
