4. Setup Instructions
- Positioning the Speakers: Place the two speakers on a flat, stable surface, such as a desk or shelf. For optimal stereo sound, position them equidistant from your listening position and spaced appropriately apart.
- Connecting the Audio Cable: Locate the 3.5mm audio jack on the speaker cable. Plug this connector into the audio output port (headphone jack) of your audio source device (e.g., computer, laptop, smartphone, MP3 player).

- Connecting the USB Power: Locate the USB-A connector on the speaker cable. Plug this connector into an available USB port on your computer, laptop, or a compatible USB power adapter (not included). The speakers draw power directly from the USB connection.
- Power On: Once both the audio and USB cables are connected, the speakers will power on automatically. There is no separate power button.
5. Operating Instructions
