How does Active Noise Cancellation work?

The technology, known as active noise-cancellation (ANC), works by using microphones to pick up low-frequency noise and neutralise it before it reaches the ear. The headset generates a sound that's phase-inverted by 180 degrees to the unwanted noise, resulting in the two sounds cancelling each other out.

Does Active Noise-Cancelling block all sound?

That's where active noise-canceling headphones come in. Active noise-canceling headphones can do everything that passive ones can do -- their very structure creates a barrier that blocks high-frequency sound waves. They also add an extra level of noise reduction by actively erasing lower-frequency sound waves.

Is Active Noise-Cancelling worth it?

Are noise-cancelling headphones worth it? Yes. If you wish to protect your hearing, reduce environmental distractions, and enjoy a better audio experience, then this technology will surprise you with its impactful results.

What is Active Noise-Cancelling vs passive?

Passive Noise Cancellation uses well designed ear cups to seal out unwanted noise. This is used for both over-ear headphones and in-ear earphones where the earbud itself will keep surrounding noise out. Active Noise Cancellation uses microphones and speakers to reduce background and surrounding noises.
