Headsets are recommended for sound quality and to avoid feedback through the microphone. Built-in loudspeakers and microphones will work, but are not ideal. Even when microphone problems occur, the presentation can be followed with audio alone. Feedback or questions can be typed using the direct messaging tool.  We do strongly recommend a microphone for optimum interactivity.
