Two pairs, one screen, on the plane

You're boarding in ten minutes and you both want to watch the same thing. Plug in, add the second pair, and you're set before the doors close.

Your Mac would only play to one of you; Tandem feeds both pairs at once, and a guest device makes adding a travel companion a single tap.

Save your travel setup as a preset — headphones, volumes, trim — so the next flight picks up right where you left off. No fiddling, no re-pairing.
