When it comes to earbuds, one of the most debated topics is the relevance of Active Noise Cancellation (ANC). ANC is a feature that uses one or more microphones to capture ambient noise, and then produces a “negative” sound wave to cancel it out. But do earbuds really need ANC to be effective? In this article, we’ll delve into the world of earbuds and explore the benefits and drawbacks of having ANC.
The Evolution of Earbuds
Earbuds have come a long way since their introduction in the 1980s. Initially, they were bulky, uncomfortable, and provided poor sound quality. However, with advancements in technology, earbuds have become smaller, more comfortable, and offer superior sound quality. The introduction of wireless earbuds, also known as true wireless earbuds, has further revolutionized the industry.
In recent years, ANC has become a staple feature in many earbuds, particularly in high-end models. But what exactly is ANC, and how does it impact the overall performance of earbuds?
What is Active Noise Cancellation (ANC)?
ANC is a technology that uses one or more microphones to capture ambient noise, such as the sound of the engine, air conditioning, or background chatter. The microphone(s) then send the sound signals to an amplifier and a processing unit, which produces a “negative” sound wave to counteract the ambient noise. This results in a quieter listening experience, allowing you to focus on the music or podcast without distractions.
Types of ANC
There are two types of ANC:
- Feedforward ANC: This type of ANC uses one or more microphones placed on the outside of the earbud to capture ambient noise. The microphone(s) then send the sound signals to the amplifier and processing unit, which produces the “negative” sound wave.
- Feedback ANC: This type of ANC uses a microphone placed inside the earbud, near the driver. The microphone captures the sound that has already entered the earbud and sends it to the amplifier and processing unit, which produces the “negative” sound wave.
The Benefits of ANC in Earbuds
ANC in earbuds offers several benefits, including:
- Improved Sound Quality: By reducing ambient noise, ANC allows you to focus on the music or podcast, resulting in a more immersive listening experience.
- Increased Productivity: With a quieter listening environment, you can concentrate better, making ANC earbuds ideal for commuters, students, or professionals.
- Better Noise Isolation: ANC earbuds can reduce noise by up to 20-30 decibels, making them perfect for noisy environments like airplanes, buses, or trains.
- Enhanced Voice Calls: ANC can also improve voice call quality by reducing background noise, making it easier to communicate with others.

- Pressure and Discomfort: Some users may experience pressure or discomfort when wearing ANC earbuds, particularly if they don’t fit snugly.
ANC-less Earbuds: A Viable Alternative?
While ANC earbuds offer several benefits, there are instances where ANC-less earbuds might be a better option:
- Better Sound Quality: Some audiophiles argue that ANC can alter the sound signature of earbuds, affecting the overall sound quality. ANC-less earbuds can provide a more accurate sound reproduction.
- Longer Battery Life: Without ANC, earbuds can offer longer battery life, making them ideal for extended listening sessions or travel.
- Cost-Effective: ANC-less earbuds are generally cheaper than their ANC-enabled counterparts, making them a more affordable option for those on a budget.
Noise-Isolating Earbuds: A Middle Ground?
Noise-isolating earbuds, also known as passive noise-isolating earbuds, offer a compromise between ANC and ANC-less earbuds. These earbuds use a combination of materials and design to block ambient noise, without the need for ANC.
Noise-isolating earbuds can provide:
- Better Sound Quality: By blocking ambient noise, noise-isolating earbuds can improve sound quality, without affecting the sound signature.
- Cost-Effective: Noise-isolating earbuds are generally cheaper than ANC earbuds, making them a more affordable option.
- Comfortable Fit: Noise-isolating earbuds often provide a snug, comfortable fit, reducing pressure and discomfort.
Conclusion
In conclusion, whether earbuds are better with or without ANC depends on your specific needs and preferences. If you prioritize improved sound quality, increased productivity, and better noise isolation, ANC earbuds might be the better option. However, if you’re on a budget, prefer a more accurate sound reproduction, or prioritize longer battery life, ANC-less earbuds or noise-isolating earbuds might be a better fit.
Ultimately, the decision to choose ANC earbuds or ANC-less earbuds depends on your individual requirements. By considering the benefits and drawbacks of ANC, you can make an informed decision and find the perfect earbuds for your needs.

What is ANC in earbuds?
Active Noise Cancellation (ANC) is a technology used in earbuds to reduce unwanted ambient sounds. It works by using one or more microphones to capture ambient noise, and then producing a “negative” sound wave to cancel it out. This results in a quieter listening experience, with less external noise interference. ANC is especially useful in noisy environments, such as public transportation, open offices, or during exercise.
ANC is not the same as noise isolation, which is a passive method of blocking sound through physical barriers, such as ear tips or cushions. While noise isolation can be effective, ANC is a more advanced technology that can provide better noise reduction, especially in the low-frequency range.
Do earbuds with ANC really make a difference?
Earbuds with ANC can make a significant difference in the listening experience, especially for commuters, travelers, or those who work in noisy environments. By actively cancelling out background noise, ANC earbuds can help you focus on the music, podcast, or voice call, and reduce listener fatigue. Additionally, ANC earbuds can also help you hear your music more clearly, as you don’t have to crank up the volume to overcome background noise.
In our tests, we found that earbuds with ANC can reduce ambient noise by up to 20-25 decibels, which is significant. This can be especially beneficial for people who are sensitive to noise, or those who have trouble sleeping due to external noise. However, it’s worth noting that ANC may not work as well in very loud environments, such as construction sites or rock concerts.
Are ANC earbuds worth the extra cost?
