Noise-canceling Headphones FAQ
What are noise-cancelling headphones?
Noise-cancelling headphones are a special type of headphones which suppress unwanted ambient sounds using active noise control. This is distinct from passive headphones which, if they reduce ambient sounds at all, use techniques such as soundproofing .
How do active noise cancelling headphones work?
Active noise-canceling (ANC) headphones use phase cancellation to detect and block external sounds for better listening. This involves the creation of frequencies that are identical but opposite to the ambient noise frequencies. When played back together, they cancel each other out, resulting in silence.
Are noise-cancelling headphones passive?
Noise cancellation to eliminate ambient noise is never passive because of the circuitry required, so references to passive noise cancellation actually are referring to products featuring sound isolation. To prevent higher-frequency noise from reaching the ear, most noise-cancelling headphones depend on sound isolation or soundproofing.
Are noise cancelling headphones worth it?
Noise cancelling headphones can help keep you focused in a noisy office or block out engine noise on planes, trains, or buses. Not all noise cancelling technology performs the same, and there are now many options in every possible price range, making it hard to know which ones are worth it.
What are the best noise cancelling headphones?
The Bose QuietComfort Ultra Headphones Wireless are the best noise cancelling headphones we've tested. These premium over-ears are outfitted with the manufacturer's CustomTune technology, meaning the headphones can adjust their sound and noise cancelling performance based on your hearing abilities and surroundings.
