Best Practice: Using blue tooth may cause sync issues between Audio and Video.

As a best practice, we do not recommend that attendees use Blue Tooth connected headphones. This can result in sync issues. The video and audio may start out only very slightly out of sync at the beginning of the presentation but will continue to get more out of sync as the presentation progresses.

If an attendee has no alternative, we recommend they refresh when they being to notice a distinct disparity between the audio and video.
