Do you know the difference between active and passive noise cancelling?


Active noise cancellation is the technology described above, where microphones and speakers work together to reduce or remove background noises. It was originally only found in larger over-the ear headphones that could contain the hardware required for the technology , but never models have made it possible for active noise-cancelling technology to be built into in-ear headphones.

Passive noise cancelling works differently.This uses specially designed hardware such as ear cups and seals to simply seal out the background noise. A little like earmuffs, this essentially inhibits the sound waves from reaching your eardrums. It is not usually as effective as active noise cancellation but certainly has its benefits.
