How to use

Position the speakers on a stable surface at either side of your monitor for optimal stereo separation. Connect the wired cable to the computer's headphone or line-out jack and power the speakers if a separate power connector is provided. Adjust the system volume from the computer and, if available, use any onboard speaker volume control to fine-tune listening level. Keep the speakers free of obstructions to avoid muffled sound.

Recommendations

For clear voice reproduction, place the speakers at ear height and maintain moderate volume levels. Use in small to medium-sized rooms for best perceived balance; for deeper bass or high-volume needs, consider an additional subwoofer or higher-power system.
