Hi @Zoub an FM transmitter just creates a “radio station” on an FM frequency, so you can use any radio tuner to play back the audio wirelessly. There is no pairing and no delay, audio/video will always be in sync. Since it’s just a broadcast you can also use as many headphones or speakers as you like. We had for example someone who created a drive-in theatre where every car played the movie’s audio on their sound system.
