3. Operating the Speakers
Once connected, the Yoidesu Mini Speakers operate by playing audio from your source device. They are designed for personal listening, providing sound that is audible to the user without being disruptive to others nearby.

- Audio Playback: Start playing audio (music, podcast, audiobook) on your device, and the sound will be emitted through the speakers.
