Ett - Features - Active Noise Cancellation (ANC) & Transparency Mode

Ett features three audio features, Active Noise Cancellation (ANC), Transparency mode and Normal (Off) mode.

The Active Noise Cancellation (ANC) feature in Ett reduces outside noise which allows you to fully immerse yourself in your own world.

Transparency mode works the opposite way and instead amplifies sounds in the background, enabling your spatial awareness. With this, you can stay alert to your surroundings without having to take out an earbud, or simply hear your own voice while on a phone call.

As soon as your phone recognizes that a phone call is incoming, Ett will automatically pause what you are listening and switch to transparency mode, then let you decide whether to answer the phone call or not.
The transparency mode will be on during the call regardless of use of ANC. When you end the phone call, Ett goes back to normal mode or ANC mode depending on how you were using the earbuds before the call.

How does Active Noise Cancellation (ANC) work?

The mechanics behind Active Noise Cancellation is in its name. The built-in microphones on Ett listen to the noise outside the earbuds while using the speaker to emit the same noise - but inverted - inside, reducing the outside noise nearly entirely. The ANC in Ett uses Feed Forward technology, which uses the microphone on the outside of the earbud to forward noise to the internal processor.

Feed Forward technology works best when used in surroundings that have a static low-frequency noise, for example in transportation (cars, public transport, or airplanes). However, you may not notice a significant difference with high-frequency noise (such as people talking) or if the noise is irregular.
