Active noise cancelling over-ear headphones have become increasingly popular in recent years, offering users a way to enjoy their music or audio content without the distraction of external noise. These headphones use advanced technology to cancel out unwanted sounds, providing a more immersive and enjoyable listening experience.
Active noise cancelling headphones work by using built-in microphones to detect external noise, and then producing sound waves that are the exact opposite of the incoming noise. This cancels out the unwanted sounds, allowing the listener to focus on their audio without any distractions.
The concept of active noise cancelling technology dates back to the 1950s, when it was first developed for use in aviation headsets. Over the years, the technology has evolved and improved, making it more accessible and affordable for consumers. Today, active noise cancelling over-ear headphones are available from a variety of brands and offer a range of features to suit different needs and preferences.
One of the advantages of using over-ear headphones for noise cancelling is their ability to provide better isolation from external noise compared to in-ear headphones. The larger ear cups of over-ear headphones help to block out more ambient noise, creating a more immersive listening experience. Additionally, over-ear headphones often have better sound quality and comfort compared to in-ear options.
Understanding the Technology Behind Active Noise Cancelling
To understand how active noise cancelling works, it’s important to first understand sound waves and how they interact with each other. Sound waves are vibrations that travel through a medium, such as air or water. When two sound waves meet, they can either reinforce each other (constructive interference) or cancel each other out (destructive interference).
Active noise cancelling headphones use this principle of destructive interference to cancel out external noise. The headphones have built-in microphones that pick up the incoming sound waves from the environment. These sound waves are then analyzed by the headphones’ electronic circuitry, which generates a sound wave that is the exact opposite of the incoming noise.
When the generated sound wave meets the incoming noise, they cancel each other out, effectively reducing or eliminating the external noise. This allows the listener to hear their audio content without any distractions from the surrounding environment.
The components of active noise cancelling headphones include the microphones, electronic circuitry, and speakers. The microphones pick up the external noise, the electronic circuitry analyzes and processes the sound waves, and the speakers produce the sound waves that cancel out the external noise.
How Active Noise Cancelling Works in Over-Ear Headphones
Active noise cancelling technology can be found in both over-ear and in-ear headphones, but over-ear headphones generally provide better noise isolation due to their larger ear cups. The larger ear cups help to block out more ambient noise, creating a more immersive listening experience.
Over-ear headphones also have more space for additional components, such as larger drivers and more advanced electronics. This allows for better sound quality and more effective noise cancellation compared to in-ear options.
There are many popular over-ear noise cancelling headphones on the market today. One example is the Bose QuietComfort 35 II, which is known for its excellent noise cancellation and comfortable fit. Another popular option is the Sony WH-1000XM4, which offers industry-leading noise cancellation and high-quality sound.

Factors that Affect the Effectiveness of Active Noise Cancelling
While active noise cancelling technology is effective at reducing external noise, there are several factors that can affect its effectiveness. One factor is the type and frequency of the external noise. Some types of noise, such as low-frequency sounds like engine rumble or air conditioning hum, are easier to cancel out compared to high-frequency sounds like voices or sirens.
The quality of the noise cancelling technology itself also plays a role in its effectiveness. Higher-end headphones often have more advanced electronics and better algorithms for analyzing and canceling out sound waves. Cheaper headphones may not be as effective at reducing external noise.
Battery life and charging capabilities are also important factors to consider. Active noise cancelling headphones require power to operate, so it’s important to choose headphones with a long battery life or the ability to charge on the go. Some headphones also offer quick charging capabilities, allowing for shorter charging times.
Price and brand reputation are also factors to consider when choosing active noise cancelling over-ear headphones. Higher-end brands often have better technology and build quality, but they also come with a higher price tag. It’s important to find a balance between budget and quality when making a purchasing decision.
The Importance of Proper Fit for Active Noise Cancelling Over-Ear Headphones
The fit of over-ear headphones plays a crucial role in the effectiveness of their noise cancelling capabilities. A proper fit helps to create a seal around the ears, blocking out more external noise and allowing the active noise cancelling technology to work more effectively.
When choosing over-ear headphones, it’s important to consider the size and shape of your head and ears. Some headphones have adjustable headbands and swiveling ear cups, allowing for a more customizable fit. It’s also important to consider the weight and comfort of the headphones, as they will be worn for extended periods of time.
To find the right fit for over-ear headphones, it’s recommended to try them on and adjust them to your liking before making a purchase. It’s also helpful to read reviews and recommendations from other users who have similar head and ear sizes.

Active Noise Cancelling vs. Passive Noise Isolation: What’s the Difference?
Passive noise isolation is another method used to block out external noise, but it works differently from active noise cancelling. Passive noise isolation relies on physical barriers, such as the design of the headphones or ear tips, to block out external noise.
In-ear headphones with silicone or foam ear tips create a seal in the ear canal, preventing external noise from entering. Over-ear headphones with closed-back designs also help to block out external noise by creating a physical barrier between the ears and the surrounding environment.
While passive noise isolation can be effective at reducing external noise, it is not as effective as active noise cancelling technology. Active noise cancelling headphones actively generate sound waves to cancel out external noise, whereas passive noise isolation relies on physical barriers to block out noise.
Both active noise cancelling and passive noise isolation have their pros and cons. Active noise cancelling is more effective at reducing external noise, but it requires power to operate and can be more expensive. Passive noise isolation is more affordable and doesn’t require power, but it may not be as effective at blocking out all types of external noise.
