When shopping for headphones, you may encounter terms like active noise cancellation (ANC) and passive noise cancellation. Let’s delve into what each means and how they can improve your listening experience.

Active Noise Cancellation (ANC)

Active noise cancellation is a sophisticated technology that uses built-in microphones and speakers to reduce background noise. Here’s how it works: the microphones capture ambient sounds, and the system creates sound waves that are the exact opposite (anti-phase) to cancel them out. This technique is particularly effective at reducing low-frequency noises, like the hum of an airplane engine or city traffic. ANC headphones are ideal for commuters and frequent flyers who wish to enjoy immersive sound without interruption.

Passive Noise Cancellation

In contrast, passive noise cancellation is a simpler approach that relies on physical barriers to block sound. This involves the use of soundproof materials and designs, such as cushioned ear cups that fit snugly and seal around your ears, preventing external noise from intruding. While not as advanced as ANC, passive noise cancellation is still effective and a popular choice for those seeking a more affordable option to minimize high-frequency sounds like office chatter.

Choosing the Right Headphones

The decision between active and passive noise cancellation often depends on your specific needs and budget. While ANC headphones offer superior noise reduction, they tend to be pricier and require power for operation. On the other hand, passive noise cancellation headphones excel in affordability and simplicity.
