This application provides a stereo networking method, an electronic device, an audio device, and a storage medium. In a system including the electronic device and the audio device, the audio device generates a Bluetooth broadcast message and sends to the electronic device, where the Bluetooth broadcast message indicates whether the audio device has established stereo and whether the audio device is allowed to establish stereo. When determining, based on the Bluetooth broadcast message, that a second audio device available for establishing stereo exists, the electronic device pops up a stereo establishment pop-up box, to ask a user whether to allow the electronic device to establish stereo or re-establish stereo. Based on short-range communication, the electronic device may directly and automatically discover an audio device available for establishing stereo, and establish stereo with the audio device based on a user requirement.
