Fogel’s pioneering work laid the groundwork for future innovators to build upon. However, it wasn’t until the 1980s that the first practical applications of noise cancellation began to emerge.
The First Noise Cancelling Headphones
In 1989, a company called Bose launched the first commercial noise-cancelling headphones, the Bose QuietComfort 1. These bulky, over-ear headphones used a revolutionary technology called “Active Noise Reduction” (ANR), which employed microphones to capture ambient noise, and then generated a “negative” sound wave to cancel it out. This innovation marked the beginning of a new era in noise cancellation, but earbuds would have to wait their turn.
The Advent of Noise Cancelling Earbuds
Fast-forward to the early 2000s, when the first noise-cancelling earbuds began to take shape. In 2004, a company called Earbud Technology Corporation (now known as AfterShokz) filed a patent for an “Active Noise Cancellation Earbud.” This early design used a combination of microphones and processing algorithms to suppress ambient noise. However, these early earbuds were not without their limitations. They were often bulky, expensive, and sacrificed sound quality for the sake of noise cancellation.
The Game-Changing Arrival of Bose QuietComfort Earbuds
In 2019, Bose revolutionized the earbud landscape with the launch of the QuietComfort Earbuds. These sleek, wireless earbuds boasted advanced noise-cancelling technology, combined with exceptional sound quality. The QuietComfort Earbuds employed a sophisticated system of microphones, processing algorithms, and proprietary noise-cancelling technology to deliver an unparalleled listening experience.
Bose’s Secret Sauce: Advanced Noise Cancellation
So, what sets the Bose QuietComfort Earbuds apart from their predecessors? The answer lies in their advanced noise-cancelling technology. Bose’s proprietary system uses a combination of:
- Microphones to capture ambient noise
- Processing algorithms to analyze and generate a “negative” sound wave
- Proprietary noise-cancelling technology to eliminate unwanted noise
This potent combination enables the QuietComfort Earbuds to effortlessly silence background noise, immersing listeners in a world of pure, unadulterated sound.

Fogel’s initial patent to the revolutionary Bose QuietComfort Earbuds, innovation has driven this technology forward. As we look towards the future, one thing is certain – noise-cancelling earbuds will continue to transform the way we experience sound, silencing the chaos and bringing us closer to the music, podcasts, and silence we love.
What is noise cancellation technology?
Noise cancellation technology is a method used to reduce unwanted ambient sounds using one or more microphones to capture ambient noise, and then producing a “negative” sound wave to cancel it out. This technology is commonly used in headphones and earbuds to provide a more immersive listening experience.
In noise-cancelling earbuds, the microphone is usually placed on the outer casing of the earbud, where it can pick up ambient noise. The microphone then sends the sound signals to an amplifier and a processing unit, which generates an “anti-noise” signal that is the exact opposite of the ambient noise. This anti-noise signal is then played through the earbud’s driver, effectively cancelling out the ambient noise.
How do noise-cancelling earbuds differ from regular earbuds?
Noise-cancelling earbuds differ from regular earbuds in their ability to actively eliminate ambient noise, rather than just blocking it passively with ear tips or cushions. Regular earbuds rely on physical barriers to block out noise, whereas noise-cancelling earbuds use advanced technology to actively eliminate noise.
This means that noise-cancelling earbuds can provide a much more immersive listening experience, with less distraction from background noise. They are particularly useful in noisy environments such as planes, trains, and buses, or in open-office settings where there may be a lot of background chatter.
Are noise-cancelling earbuds worth the extra cost?
Whether or not noise-cancelling earbuds are worth the extra cost depends on your personal preferences and listening habits. If you value a distraction-free listening experience and often find yourself in noisy environments, then noise-cancelling earbuds may be a worthwhile investment for you.
On the other hand, if you mostly listen to music in quiet environments or don’t mind background noise, then regular earbuds may be a more cost-effective option. Additionally, some people may not notice a significant difference in noise cancellation, so it’s worth trying out noise-cancelling earbuds before committing to a purchase.
Do noise-cancelling earbuds work with all types of noise?
Noise-cancelling earbuds are most effective against constant, low-frequency sounds such as engine rumble, airplane noise, or background chatter. They can also help to reduce mid-frequency sounds like keyboard typing or footsteps.
However, noise-cancelling earbuds may not be as effective against high-frequency sounds like screaming children or sharp, sudden noises. Additionally, wind noise can be a challenge for noise-cancelling earbuds, as it can be difficult to distinguish between the wind noise and the audio signal.
Can I use noise-cancelling earbuds to sleep?
Yes, noise-cancelling earbuds can be a great option for sleeping, especially for individuals who have trouble falling asleep due to background noise. Noise-cancelling earbuds can help to block out snoring, traffic noise, or other sounds that may be disturbing your sleep.
However, it’s worth noting that noise-cancelling earbuds may not be the most comfortable option for sleeping, especially if you’re a side sleeper. Additionally, some people may find that the noise cancellation is not effective enough to block out all noise, or that the earbuds are not comfortable to wear for extended periods of time.
Are noise-cancelling earbuds comfortable to wear?
Noise-cancelling earbuds can be just as comfortable to wear as regular earbuds, depending on the design and fit. Many noise-cancelling earbuds come with ergonomic design and premium materials to ensure a comfortable fit.
However, some people may find that the added components for noise cancellation make the earbuds slightly bulkier or heavier, which can affect comfort. It’s also important to choose an earbud that fits snugly in your ear to ensure optimal noise cancellation and sound quality.
Do noise-cancelling earbuds drain battery faster?
Yes, noise-cancelling earbuds typically require more power to operate the noise cancellation technology, which can result in shorter battery life. However, many modern noise-cancelling earbuds have optimized battery life to minimize the impact of noise cancellation.
Some noise-cancelling earbuds may have features such as automatic shut-off or power-saving modes to help extend battery life. Additionally, many earbuds come with carrying cases that provide additional battery life, so you can recharge your earbuds on the go.
