Passive

Explanation:

Passive listening is one in which we listen, 100% listen without interruption, without precipitation, all the time, everywhere ,even if we are not aware.

Passive listening is one in which, while listening, we do not think about what we are going to talk about next, we do not agree or disagree. In those moments, we simply listen, aware or not of what we hear and who we hear.
