First, not all browsers support setting the output destination, so be aware of that.

For browsers that do support it, the device object has an audio property which has an availableOutputDevices property that lists the available destinations. There is a vanilla JS example in the documentation for creating a drop down menu and updating the audio output. I recommend you take a look at that and translate it to React.
