Q1. What is Noise Cancellation ?

Basically Noise Cancellation means cancelling out the unwanted external noises using noise control mechanisms. Basically noise cancellation can be sub-divided into two categories which have been outlined below:

  • Active Noise Cancellation: This is the advanced technology used particularly by noise cancellation headphones. Under active noise cancelling there is an inbuilt circuitry inside the headphones which analyze the wavelength of the noise coming in. Post Analyzation a mirror signal to the noise with negative wavelength is induced into the output sound; thus cancelling the noise and as a result you get to hear remarkably clear music.
  • Passive Noise Cancellation: This is not basically a noise cancellation technique but it is more of a sound proofing technique. Under this the passive noise cancellation headset for music is built so as to envelop your ears completely. As a result the outside noise is cut to a considerable level; however this is not at par with active noise cancelling technique.

Further more noise cancellation comes in the attached microphones as well as headsets. Noise cancellation in microphone makes you have a clear conversation while on call. Noise cancellation in headsets, as described above, is great for listening your favorite tracks without any external interference.

Q5. How to Choose Best Noise Cancelling Headphones?

Now this is the most important question which I have come across. We often get confused as there are so many options available for noise cancellation headphones in the market. So you should better employ the following ways to choose a best one for you:

  • First of all you must know the difference between ‘noise-isolation’ and ‘noise-cancellation’ as both are not the same. Noise-isolation headphones just minimize the external sound to a bit while noise-cancellation, as you already know now, has good amount of technology invested in it to give your ears a pleasurable music experience.
  • You should decide whether you want in-ear, ear-pads or full sized models.
  • Ask for trying them out. If you are allowed to try or the shop has a testing sample then it’s the best scenario as you can test them out in the hustle and bustle of the shop, just by toggling on the active noise cancellation, without playing anything to see what surrounding sounds you can hear plus you can also make your friend talk to you while the active noise cancelling is in operation. Testing a pair before buying will give you quite decent idea of which noise cancellation headsets you should pick up.
  • While trying them out you can check out their fitting too. If you are looking for long hours consistent usage; fitting is an important factor to be considered. There is absolutely no use; buying a head phone with a big price tag later on to find out it gives you headache or ear pain.
  • Also, apart from these play your music too for checking out the audio quality as you shouldn’t go for noise cancellation over audio quality and vice-versa. There must be a balance.
  • You must check the battery life by reading reviews of various noise cancellation headsets. Go for a pair which has a decent battery life as you don’t want the battery to die when you are in middle of travelling or using your noise cancellation headset for sleeping in an air-plane.
  • Check the warranty too. Now you know that, in case of active noise cancelling, electronic circuitry are in-built inside your headphones. You never know when the electronic circuits can fail. So do a double check on warranty and after sales service. Again you can check reviews for getting an idea about the complaints coming for a particular headset and after sales service.

Last, be in no hurry to buy a device. Try out as many models and as many shops as you can before shelling your hard earned bucks.
