Careful and attentive listening is a key component of successful usability testing. UI and UX designers will find the results from their end-user testing sessions far more productive if they let their ears do most of the work. Allowing the users the freedom to talk uninterrupted will put those observing the testing in the best situation to absorb information through user communication. When focused on absorbing information instead of talking over it, you are able to collect pure, unbiased data and turn it into useful information that will help guide your UI decisions.
