At first, noise cancelling headphones were primarily enjoyed by frequent travelers or those who worked in loud spaces. There’s something soothing and magical about a quiet journey in a plane without needing to use the uncomfortable earplugs provided by the airline. And with noise cancelling headphones, you can listen to music or an audiobook clearly and peacefully without needing to turn up the volume to drown out what’s going on around you. Nowadays, in our busy connected world they are a must have addition to your list of digital devices. If you travel a lot, use public transport frequently or work in a noisy office, you will find that noise cancelling headphones can keep the world blocked out while you enjoy your own music or audiobook.
What is noise cancelling?
There are a lot of misconceptions about noise cancelling, so before you consider this type of headphone, there are some important things you need to know.
First of all, active noise cancelling (ANC) and noise blocking are two different things. Active noise cancelling headphones can cancel out annoying low-frequency noises and bring you a quiet environment. It can filter the ambient low-frequency noise and generate a negative sound wave to cancel the ambient noise. The result is you can hear silence, and when you play music, you’ll hear pure music. Most noise cancelling headphones can cancel up to 80-95% ambient noise. Noise blocking, on the other hand, blocks all noise (not just low-frequency noise). One example of that is ear muffs used in shooting. Over-ear headphones are great noise blockers.
Noise cancelling headphones use microphones to identify if ambient noise is present. That signal is then set to dedicated electronics that create direct opposite soundwaves that go through the headphones and then to your ears. Opposite soundwaves or frequencies cancel out each other, thus negating the original noise.
What to expect from noise cancelling headphones
Noise cancelling is perfect if you find yourself in many situations when you want a quieter environment. But you have to remember that there comes inevitable disadvantages to this type of headphones. Here are some of them:1. Comes at a higher price
Noise cancelling (NC) headphones tend to cost more than regular headphones. Since it is equipped with noise-cancelling technology and microphones, it cost more money, especially if you choose the higher-end ones. A decent NC headphone comes with a price to pay, so you can also get better build quality, better comfort and of course, better sound.2. Needs power
Unlike typical plug and play headphones, noise cancelling headphones use rechargeable batteries and for some, changeable ones. The NC technology won’t work without power.3. Has lower sound quality
Overall, noise cancelling headphones have lower sound quality compared to ordinary headphones. The technology produces counter frequencies to negate noise, but you can’t expect that it will be 100% accurate all the time. Sometimes, the frequencies of the original music can get cancelled, distorting the overall sound quality. Audiophiles have accepted the fact that noise cancelling reduces the sound quality of any headphones, even the most expensive ones. So, if your primary concern is to be able to listen to music clearly and more powerfully, you may need to think twice if you really want a noise cancelling option.4. Gives pressure to the ears
Noise cancelling headphones can make your feel like your ears are under pressure. It can feel uncomfortable as you wear the headphones for a long time. Find a decent pair that you will feel most comfortable with.
5. Sensitive to wind
The enemy of a noise cancelling headphone is strong winds. If it’s blowing outside and making sounds, the microphone can pick up the sounds of the wind and make a whole mess of the sound you are listening to on the headphones. This is why NC headphones are not advisable for outdoor use.
