CodePudding user response：

You can use https://github.com/react-native-device-info/react-native-device-info#isHeadphonesConnected

// Tells if the device is connected to wired headset or bluetooth headphones
DeviceInfo.isHeadphonesConnected().then((enabled) => {
  // true or false
});

CodePudding user response：

you can use react-native-device-info

https://www.npmjs.com/package/react-native-device-info

it have a method isHeadphonesConnected()

Tells if the device is connected to wired headset or bluetooth headphones

  DeviceInfo.isHeadphonesConnected().then((enabled) => {
  if(enabled){
     // implementation for the case when headphone is connected
}else{
    //implementation for the case when headphone is not connected
});

and it also contain a hook through which you can check whether wired headset or bluetooth headphones are connected

useIsHeadphonesConnected

Tells if the device is connected to wired headset or bluetooth headphones.

This hook subscribes to the event, RNDeviceInfo_headphoneConnectionDidChange , and updates the result field accordingly example

 import { useIsHeadphonesConnected } from 'react-native-device-info';

const { loading, result } = useIsHeadphonesConnected(); // { loading: true, result: false}

<Text>{loading ? 'loading...' : result}</Text>;
