While on a call you can manually direct the audio to the hearing aids.

Eg says:

"Adjust the audio during a call

To change the volume, press the volume buttons on the side of iPhone.

Or swipe down on the call banner, then do any of the following:

  • Mute: Tap the Mute button.
  • Put the call on hold: Touch and hold the Mute button.
  • Talk handsfree: Tap the Audio button, then choose an audio destination." (Hearing Aids)

Another option is to automatically direct calls to the hearing aids:

You can automatically direct the audio of phone or FaceTime calls to your hearing device.

iPhone can also automatically answer calls after a length of time you set.

  1. Go to Settings  > Accessibility > Touch > Call Audio Routing, then choose an audio destination.
  2. Tap Auto-Answer Calls, turn on Auto-Answer Calls, then set the duration of time before the call is answered by tapping or .


During a call, you can switch the audio routing from your hearing aid to the iPhone speaker by removing the hearing aid from your ear.
