Noise-Cancelling vs Noise-Isolating Headphones: Understanding the Key Differences
If you're in the market for a new pair of headphones, you've likely come across the terms "noise-cancelling" and "noise-isolating." While they may sound similar, these two types of headphones work in fundamentally different ways to reduce unwanted noise. In this article, we'll explore the differences between noise-cancelling and noise-isolating headphones to help you decide which type is best for you.
Noise-cancelling headphones use advanced technology to actively cancel out external noise. They do this by using built-in microphones to pick up external sounds, and then creating an opposite sound wave that effectively cancels out the noise. This makes them particularly effective at reducing low-frequency sounds, such as the hum of an airplane engine or the rumble of a train. On the other hand, noise-isolating headphones use physical barriers to block out external noise. They work by creating a seal around your ears that prevents sound from entering or leaving the headphone cups. This makes them particularly effective at reducing mid-to-high frequency sounds, such as voices or traffic noise.
Both noise-cancelling and noise-isolating headphones have their pros and cons, and the right choice for you will depend on your individual needs and preferences. Noise-cancelling headphones are great for frequent travellers or anyone who needs to block out low-frequency noise, while noise-isolating headphones are ideal for those who need to reduce mid-to-high frequency sounds in a noisy environment. By understanding the differences between these two types of headphones, you can make an informed decision and choose the best option for your needs.
Noise Isolating Headphones
When it comes to headphones, there are generally two types of noise-cancelling technology: active noise cancellation and passive noise isolation. In this section, we will discuss noise isolating headphones, which are also known as passive noise cancellation headphones.
Passive Noise Isolation
Passive noise isolation is a method that blocks ambient noise from entering your ears by creating a physical barrier between your ear and the outside world. This is achieved through the use of ear cups that fit snugly around your ears, creating a seal that prevents sound from entering or leaving.
This method is similar to using earplugs or headphone earmuffs, which also present a physical barrier that blocks unwanted sounds. The effectiveness of this method depends on how good the headphone is at physically blocking out noise from entering the ear.
Effectiveness
The effectiveness of noise isolation depends on how well the headphones fit on the user. There should be as little leakage as possible to ensure the best noise isolation. The material used to make the headphones also plays a role in how well they block out noise.
Noise isolating headphones are generally more effective at blocking out high-frequency sounds, such as the hum of an air conditioner or the sound of an airplane engine. However, they may not be as effective at blocking out low-frequency sounds, such as the rumble of a train or the bass of music.
In general, noise isolating headphones are a good option for those who want to block out ambient noise without spending a lot of money on noise-cancelling headphones. They are also a good option for those who want to use headphones in loud environments, such as a construction site or a noisy office.
Overall, noise isolating headphones are a great option for those who want to block out ambient noise without breaking the bank. They are generally more effective at blocking out high-frequency sounds and are a good option for those who want to use headphones in loud environments. However, they may not be as effective at blocking out low-frequency sounds as noise-cancelling headphones.
Noise-Cancelling Headphones
When it comes to noise-cancelling headphones, they are equipped with advanced technology that helps to reduce ambient noise. This technology is known as active noise cancellation, which is different from noise isolation.
Active Noise Cancellation
Active noise cancellation uses electronics to send out sound waves that nullify the ones coming from the environment. The sound waves "cancel" each other out, effectively reducing ambient noise, mostly low-frequency sound waves, by an average of 30dB.
Circuitry
Noise-cancelling headphones come with advanced circuitry that helps to reduce external noise. The circuitry is designed to analyze the incoming sound waves and create an opposite sound wave to cancel out the noise.
Power Source
Most noise-cancelling headphones require batteries to power the active noise cancelling technology. The battery life can vary depending on the brand and model of the headphones. Some headphones offer up to 20 hours of battery life, while others offer up to 40 hours of battery life.
Effectiveness
Noise-cancelling headphones are highly effective in reducing noise, especially low-frequency noise. They are ideal for use in noisy environments such as airplanes, trains, and busy offices. The noise reduction is so effective that it creates a 180-degree sound field that makes it feel like you are in a quiet room.
In conclusion, noise-cancelling headphones are a great investment if you are looking for a way to reduce external noise. They use advanced technology to cancel out noise and create a quiet environment. However, they do require batteries to power the active noise cancelling technology, so it's important to keep them charged.
Noise Isolating vs. Noise-Cancelling Headphones
When it comes to headphones, noise isolation and noise cancellation are two popular methods for reducing external noise. While they may sound similar, there are some key differences between the two technologies. In this section, we will explore the design, sound quality, comfort, pros and cons, and verdict of noise-isolating and noise-cancelling headphones.
Design
Noise-isolating headphones work by physically blocking out external noise. They do this by creating a seal around your ear or in your ear canal, which prevents outside noise from entering. This type of headphone is typically available in in-ear or over-ear designs.
On the other hand, noise-cancelling headphones use active noise cancellation (ANC) technology to cancel out external noise. They do this by using microphones to pick up external noise and then creating an opposite sound wave to cancel it out. Noise-cancelling headphones are available in over-ear and on-ear designs.
Sound Quality
When it comes to sound quality, noise-cancelling headphones are generally considered to be superior. They are designed to cancel out external noise, which means you can enjoy your music without any distractions. However, this does not mean that noise-isolating headphones have poor sound quality. In fact, they can provide excellent sound quality, especially for mid to high frequencies.
Comfort
Both noise-isolating and noise-cancelling headphones can be comfortable to wear, but this can depend on the design and materials used. Noise-isolating headphones can be uncomfortable if they are not the right size or if they are made from hard materials. Noise-cancelling headphones can also be uncomfortable if they are too tight or if the ear cups are not well-padded.
Pros and Cons
Here are some pros and cons of noise-isolating and noise-cancelling headphones:
Pros of Noise-Isolating Headphones
- Cheaper than noise-cancelling headphones
- No batteries required
- Effective at reducing mid to high frequencies
Cons of Noise-Isolating Headphones

- Available in both over-ear and on-ear designs
Cons of Noise-Cancelling Headphones
- More expensive than noise-isolating headphones
- Require batteries or charging
- May not be as effective at reducing mid to high frequencies
Verdict
In conclusion, noise-cancelling headphones are generally the better choice if you want to block out external noise and enjoy superior sound quality. However, noise-isolating headphones can still provide excellent sound quality, especially for mid to high frequencies. They are also a good choice if you are on a budget or prefer not to use batteries. Ultimately, the choice between noise-isolating and noise-cancelling headphones comes down to personal preference and the specific use case.
Final Thoughts
In conclusion, choosing between noise-cancelling and noise-isolating headphones depends on your specific needs and preferences. Both types of headphones have their pros and cons.
If you want to completely block out ambient sound and background noise, noise-cancelling headphones are the way to go. They use advanced electronics to cancel out external noise by creating sound waves that are the exact opposite of unwanted noise. This technology is particularly effective for low-frequency sounds such as airplane engine noise or traffic hum. Sony and Bose are two of the most well-known brands that offer high-end noise-cancelling headphones.
On the other hand, if you prefer a physical barrier between your ears and the outside world, noise-isolating headphones are a good choice. They use a tight seal inside or around your ears to block out environmental noise. In-ear headphones generally provide better noise isolation than over-ear and on-ear headphones. Earbuds are a popular choice for noise isolation since they fit snugly inside the ear canal. However, it's important to note that noise isolation can cause hearing loss if the volume is turned up too high.
Another consideration is microphone interference. Noise-cancelling headphones can sometimes interfere with the sound quality of a microphone, whereas noise-isolating headphones do not have this issue. If you frequently use headphones for phone calls or video chats, noise-isolating headphones might be a better choice.
It's also worth noting that noise-cancelling headphones can sometimes leak sound, meaning that others around you can hear what you're listening to. Noise-isolating headphones do not have this issue, as they create a physical barrier between your ears and the outside world.
In summary, both noise-cancelling and noise-isolating headphones have their advantages and disadvantages. Consider your specific needs and preferences before making a decision.
