Our Ett earphones features transparency mode which is automatically activated during phone calls.

Ett's transparency mode lets ambient noise through so you can better hear yourself speaking during phone calls.

As soon as your phone recognises that a phone call is incoming, Ett will automatically pause what you are listening to 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 the mode you were on prior to the call.
