After long searching and making reveral test, I think creating a DeviceWatcher is the most relevant solution for this. I tried it and get notifications whenever any headphone/mic is added or removed as well.

After creating the watcher, you will receive the following notifications for any device that matches your provided criteria.

• Add notification when a new device is added.
• Update notification when a property you are interested in is changed.
• Remove notification when a device is no longer available or no longer matches your filter.
