Open Control Center, tap , tap your hearing device or AirPods, then tap Live Listen.
(If you don’t see , add it to Control Center—go to Settings > Control Center, then choose Hearing.)
Triple-click the Home button, tap Hearing Devices, then tap Live Listen.
Position iPod touch near the sound source.
