One set of controls, three lenses on the same scenario. Set the earbud tech and latencies, then switch tabs to see it as a latency stack, a concert hall, or an arena. Flip Auto-Sync and watch all three lock into perfect lip-sync.

Earbud technology
Co-located live event: the display is delayed to sync earbuds — ideally to the audience centroid, never below the slowest earbud's need. A deliberate optimized delay can enhance immersion. Seats ring green→red by mismatch to the live room. Remote venues have no such constraint.
