Noise-canceling headphones are classified into two types: active and passive.

  1. Passive: They use things like thick ear cups or in-ear plugs to block out outside noise. They work without electricity or technology and are usually cheaper than active noise-canceling headphones.
  2. Active: They use special microphones and algorithms to actively cancel out background noise. To function, they require a power source, usually a battery.

When the noise-canceling feature is turned on, the headphones will listen for outside noise and send out a signal to cancel it out. Even in busy situations, this delivers a quiet and tranquil listening experience.

You may be wondering if they are worth the extra money now that you understand how they function. The answer will ultimately be determined by your unique choices and requirements. Here are some pros and cons to think about when deciding if noise-canceling headphones are a good idea for you.


  • Improved focus: It can help you focus on your music by blocking out distractions, allowing you to fully enjoy it. This is particularly useful whether working, studying, or commuting on a noisy plane or train.
  • Sound quality: It can improve the overall sound quality of your headphones. You can hear more nuances and details in your music if you block out external noise.
  • More relaxing: They may be more comfortable to wear with time. They alleviate ear fatigue by blocking out extraneous noise.
  • Better sleep: They offer a sleep mode that emits peaceful tones or white noise to aid sleep. This is especially handy if you live in a noisy area or have trouble sleeping.


  • Higher cost: They are typically more expensive than normal headphones. If you’re on a tight budget, this can be a considerable disadvantage.
  • Battery reliance: They are powered by a battery, which means they will eventually run out of juice. If you’re on a lengthy flight or in the middle of a workout, this can be inconvenient.
  • Comfort and fit: They are typically heavier and bulkier than standard headphones, making them less pleasant to wear for lengthy periods of time. Furthermore, not all noise-canceling headphones are comfortable on all head shapes and sizes, which may be an issue for some users.
  • Less sound quality: They may not give as good sound quality as normal headphones in some instances. This is due to the fact that the technology employed to filter out background noise can occasionally have an impact on the overall sound quality of the headphones.

Noise-canceling headphones are efficient in reducing background noise, however, they are not always effective at canceling out all sorts of noise. Noise-canceling headphones, for example, may not totally suppress low-frequency disturbances such as the hum of an airplane engine. Furthermore, even with noise-canceling headphones, sudden loud noises such as a car horn may be audible.
