of an airplane engine , the rumble of a train and highway noise , They do
this by producing an anti noise sound wave that interferes with , and they cancel out unwanted background noise .
You have to know that noise-cancelling headphones contain a microphone placed
near the ear and the electronic circuitry that generates the opposing sound , Noise-cancelling headphones do not emit low level
radiation and they do not pose any of the potential hazards that could stem
from frequent use of a cell phone held next to the ear .
It is very important to know that the best benefit of noise reducing headsets is the silence it creates , With these ear pieces , The music is definitely
clearer and more defined , The audio
books may be better understood , and relaxing is more readily achieved .

You have to know that they reduce the demand for complicated electronic circuitry that would be required for the noise cancellation at higher frequencies , where active cancellation is less effective , To 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 currently technically feasible .
It is very important to know that noise-cancelling headphones are ideal for studying as many students find it hard to concentrate especially when the sounds are distracting them at all times , Using noise-cancelling headphones helps the students to block out the external world and concentrate on what they need to learn , They can study in a room next to a loud roommate .

people who travel , Noise-cancelling
headphones allow these commuters to use their time well , even if that

tasks much easier .

makes them lighter for the the wearer which can add to comfort , It can be quite a drain on the device , causing the battery
levels to drop quickly if it is a battery powered device , Having a
backup method for charging the device when traveling is important when
using one of these sets .

You have to know that noise-cancelling technology can be used in the pilot headphones , in the race car driver headset , the music headphones , And the worker earmuffs as the loud noises can damage hearing , interfere with sleep , raise the blood pressure and stress levels and cause the headaches , The heart attack risk was higher among people exposed to the chronic noise .

You have to know that noise-cancelling headphones don’t require you to be completely isolated from the outside world , you can still hear the people talking around you , And you can hear non-constant noises such as a phone ringing or a knock on the door .
You should know that noise-cancelling headphones are as easy to put on and take off as any standard headphones , whereas a good number people find in-ear-canal headphones to be uncomfortable , most NC headphones are relatively luxurious with plush earpads and thick headbands .
Noise-cancelling headphones drawbacks

Everyone must know that the cost of noise-cancelling headphones
is very high , There is difference in the quality of sound when using them , Most sounds are blocked or cancelled by the design and technology of these headphones but some sounds do still get through .
You have to know that the sound of music is not altered , and the ultimate in the sound quality is possible , For a similar level of noise reduction and sound quality , The canalphones can be less expensive than noise-cancelling headphones .
You should understand that they consume more power , They usually supplied by a USB port or a battery that must be replaced or recharged , Without power , some models are unable even to function as standard headphones .

You should know that the noise-cancelling effect of these headphones is achieved by creating a sound wave that breaks down the sound waves approaching it , This requires a sound , and some people complain about a hearing a humming sound when wearing them , The sound which is actually barely perceivable also causes some people to feel pressure on their eardrum when wearing them , Those who are sensitive to this may want to limit their use , at least until they adjust to it .
You have to know that most NC headphones block only a limited range of frequencies , The high frequencies aren’t canceled nearly as well as others , NC circuitry can introduce an audible hiss or hum , along with a sense of physical pressure on your eardrums , during listening .
