{% hint style="danger" %}
Displaying as Connected ⓘ means the device is recognized as an audio device. If it only shows as Connected without ⓘ, it indicates that the Qudelix iOS app is connected to the device via a BLE (Bluetooth Low Energy) link. For more details, refer to the [iOS app connection](https://doc-kr.qudelix.com/5k/getting-started/bluetooth-pairing-ios/ios-app-connection) section.
