The Sit N Listen APP brings sound to your smart phone in public settings where multiple TV sets are playing different channels without sound. You can then hear the sound through your phone speaker or earbuds for privacy. This APP only works in establishments who have installed the Sit N Listen WAD (Wide Area Distribution) sound equipment. If you are in a bar, casino or gym that does not have the Sit N Listen equipment, this APP will not be able to connect. When you are in a Sit N Listen establishment, this APP will log on to the system wifi, and you will then be able to choose the channel you wish to hear. The sound is broadcast to your phone only when you are within wifi distance of that establishment. If your favorite bar, casino or gym does not yet have the Sit N Listen system installed, have them call 702-478-0007 and talk to our sound equipment experts so you can use this APP.
