This article delves into the world of ANC, its utility, and its effects on different scenarios.
What is ANC?
ANC, or active noise cancellation, is a technology that employs a noise-canceling system to eliminate unwanted ambient sounds. This system relies on microphones that capture external and internal audio from your earphones.
Subsequently, the active noise cancellation chipset counters these sound waves, creating a more serene listening environment.
The speakers within your earphones counteract surrounding noise by neutralizing sound waves, as described earlier.
Although ANC is most commonly associated with over-ear headphones, advancements in technology have made it more compact and battery-efficient, allowing for its integration into true wireless in-ear earphones.
Is ANC useful?
The question that often arises is, “Is ANC truly useful?” The answer is a resounding yes, with a few caveats. It’s essential to consider the scenarios where ANC proves its worth and those where it may not make a noticeable difference.
Traveling with ANC:
When it comes to traveling, ANC can be a game-changer. Whether you want to immerse yourself in a podcast, savor your favorite music, or simply shut out the cacophony around you for a peaceful journey, headphones with ANC will enhance your experience.
However, it’s worth noting that enabling ANC consumes more battery power. If you’re on a lengthy voyage and noise isn’t a significant concern, switching off ANC can help conserve battery life.
For air travel, hybrid ANC headphones are the optimal choice. They effectively target low-frequency noises like the hum of an aircraft and also higher frequencies such as human voices.
This ensures that you can escape the hustle and bustle of a crowded airplane and slip into your own world of sound.
ANC can reduce ambient noise by an average of 30 dB. When it comes to low-frequency noise sources like lawnmowers, subway rumbling, or airplane engines, ANC can significantly diminish them by as much
as 60 dB. In essence, earbuds equipped with passive noise isolation excel in reducing mid-high frequencies, while ANC excels at tackling low-frequency noise.
How do the different types of ANC compare?
There’s a multitude of ANC types available, and the table below offers a quick reference guide to the main differences:

Hybrid ANC headphones are gaining popularity due to their capacity to combat noise effectively. With time, the market has matured, prompting more manufacturers to embrace a hybrid approach, ensuring better ANC performance and more competition.
Does ANC reduce bass?
One of the most effective solutions for mitigating bothersome bass sounds is high-quality active noise-canceling headphones. These headphones can even counter low bass notes. ANC headphones, especially the top ones, are fast enough to neutralize thumping bass, ensuring a richer audio experience.
Should you buy ANC earphones or headphones?
Considering the numerous benefits ANC offers, we recommend investing in earphones or headphones equipped with this feature. While ANC may not be crucial at all times, having the option to turn it off when not needed is invaluable.
Overall, ANC enhances your music experience considerably.Even budget headphones, while not delivering extraordinary ANC, still provide some noise reduction.
Therefore, if your budget allows, consider purchasing earphones or headphones with ANC to elevate your audio experience.
