K2 features two audio modes that let you decide what you want to hear - and what you don't want to hear. These two modes are called Active Noise Cancellation (ANC), and Normal (Off) mode.
The Active Noise Cancellation (ANC) mode in K2 reduces outside noise which allows you to fully immerse yourself in your own world.
How to switch between the modes
The headphones are in Normal (Off) mode by default, where background noise is neither reduced nor amplified. By pressing the button on the K2 for 2 seconds when they are turned on, you can turn on the ANC. Press on the button again for 2 seconds to turn ANC off.
How does Active Noise Cancellation (ANC) work?
The mechanics behind Active Noise Cancellation is in its name. The built-in microphones on K2 listen to the noise outside and inside the headphones while using the speaker to emit the same noise - but inverted - which reduces the outside noise nearly entirely. K2 uses Hybrid ANC technology, which is a combination of Feed Forward and Feedback ANC technology.
