How to distinguish between AirPods and connected headphones?

Question

I have a need to check if the searched device is an AirPods device. I don’t know how to start. I hope to get your help. Thank you very much!

 AVAudioSessionRouteDescription *currentRount = [AVAudioSession sharedInstance].currentRoute;
    AVAudioSessionPortDescription *outputPort = currentRount.outputs[0];
    if ([outputPort.portType isEqualToString:AVAudioSessionPortBluetoothA2DP]) {

    } else {

    }

Answer 1

I have not much of experience with audio framework of iOS, especially with Bluetooth module. But I did some reading. You could start with this:

How can I detect whether a HFP or A2DP is connected in iOS?

And the list of BT protocols (good read):

And then to answer your question, here's the documentation of Apple for AVAudioSessionPort

https://developer.apple.com/documentation/avfoundation/avaudiosessionport?language=objc

From there you can see the constants for that structure, such as:

AVAudioSessionPortHeadphones - Output to wired headphones.

AVAudioSessionPortHeadsetMic - A wired headset’s built-in microphone.

So there. Imo, if you have these kinds of constants (and please check the other constants too), you have what you're looking for.

Hope it helps!
