Please include your iPhone model, the headphones or speaker you use, the app that was playing, and what the status row in Sound Relay said.

How Sound Relay works

  1. Open Sound Relay once and leave it running in the background.
  2. In Control Center, open the output menu and choose Sound Relay.
  3. Your audio now passes through the equalizer on its way to the headphones or speaker you were using before. The status row in the app shows which one.
  4. To stop, choose your headphones or iPhone in the output menu again.

Common questions

Sound Relay isn't listed in the output menu.
The entry is shown only while the app is running. After a restart, or after the app was swiped away, open it once.

My headphones disconnected and the music went silent.
That is on purpose: instead of playing out loud from the iPhone speaker, Sound Relay mutes and sends a notification. Your music keeps running in its app. Pause it, reconnect the headphones, or tap Play on iPhone Speaker in Sound Relay.

Can I use it with HomePod or Apple TV?
No. AirPlay outputs are not supported; with one selected, Sound Relay plays on the iPhone.
