Types of Noise Cancellation:

There are two kinds of noise-canceling headphones available in the market. You will find passive and active ones, where each has its unique features to offer you an optimal listening experience while keeping outside distractions at bay.

The passive technology will have the insulated construction of headphones to block external noise up to some extent.

Active noise cancellation headphones do a better job of cutting out background noises than passive ones. 

The advanced technology in these headgears will stop up to 100% of the surrounding sound and make you feel like your world is just for yourself, even when surrounded by other people or at an event where it’s difficult not to have any distractions around.

When playing music, how can headphones detect background noise?
