Overview of Noise Canceling Headphones

Relax and enjoy
With noise-cancelling headphones you can escape from everyday life. Fades out annoying background noise and immerses yourself in your own sound world or creates silence. Frequent travelers or open-plan office workers not only use this type of headphone for more listening pleasure, but also to get some rest.

Active and passive noise canceling

Noise-cancelling headphones reduce unwanted low-frequency noise thanks to active electronics (ANC). And this is how it works: The ambient noise is recorded by a microphone and the phase is rotated. These anti-sound waves and the noise then largely cancel each other out. Good models succeed in this acoustic trick without distorting the sound of the material to be reproduced. The right design (ear-enclosing or ear-sealing) ensures that unwanted noise in the mids and highs is contained (passive noise cancelling). There are also headphone models that only use passive noise canceling. These are by no means as powerful as models with active noise canceling.

Pros and cons of noise-cancelling headphones
Biggest benefit: Audio books and film sound in particular, which usually have a much larger dynamic range than music, can be played back much more quietly because the ambient noise does not have to be drowned out.
Disadvantage: The active electronics of the noise-cancelling headphones require batteries or rechargeable batteries. With runtimes of usually 25 to 30 hours per battery/battery set, it’s enough for a long-distance flight.

Many models can also be used as normal headphones when the noise-cancelling electronics are switched off or the battery is empty. With good models, there is no audible difference in sound compared to operation with active noise cancelling.
