This approach is preferred because it reduces the demand for complicated electronic circuitry and at higher frequencies, active cancellation is less effective. To truly cancel high frequency components (coming at the ear from all directions), the sensor and emitter for the cancelling waveform would have to be adjacent to the user’s eardrum, which is not technically feasible.

They cut out all background noise hence allow you to listen to your music at a lower volume, hence they lessen the risk of losing your hearing. Im extremely happy that i invested in these. They are particularly good for businessmen, like myself, who are frequent flyers. They block out all the surrounding noise and allow you to focus on your work and have a good sleep before your business meeting. This is where i got mine from - <a href="http://www.monstercable.com/headphones/" rel="nofollow">Noise Canceling Headphones</a> Noise CAnceling Headphones are a brilliant investment.

Drop by to see my 95 year old 'Pop', in action – wearing a noise canceling microphone/headset to dictate text at up to 150 wpm using Dragon Naturally Speaking 10, with absolutely no outside noise interference!

This proves to me it's never too late to learn about new technology…

Holds true for YOU ears? I may not be able to hear through the headphones, but I can still see the errors. Spell check can usually fix these problems. Better luck next time. </p> "The same holds true for you ears". Holds true for YOU ears? I may not be able to hear through the headphones, but I can still see the errors.
