# Hearing device support

Access information about paired hearing aid devices and streaming status.

## Overview

Overview Companion apps for hearing device manufacturers might offer certain features, like remote fitting and hearing device health checks, that rely on streaming audio to the hearing devices. If a user disables audio streaming on their Apple device, these features might become unavailable. This API gives your app the ability to check the state of the streaming preferences, so you can ask users to temporarily enable streaming to use your app’s features. You can also query other information about streaming capabilities and paired hearing devices. Use this API to check: The state of the streaming preferences for the hearing device in each ear Whether the iOS device supports bidirectional streaming The Bluetooth UUIDs of the paired hearing devices that match your app’s hearing.aid.app entitlement
