Product Features
- Simple Elliptical Structure: Constructed from metal and high-quality plastics, ensuring stability and preventing vibrating sounds. The black and silvery color scheme, complemented by a blue oval lamp ring, provides a modern aesthetic. The low-voltage digital power allows for a maximum output of 5W x 2, delivering clear, bright, rounded, and thick audio from a compact body (3.94x2.76x2.95 inches).

- Superb Sound Quality: Features outstanding bass quality for small speakers, achieved through a built-in bass diaphragm, closed cavity, and Low Frequency Aid Design. This unique acoustic resonator structure enhances sound penetration and power, compensating for the typical bass limitations of mini 2.0 speakers.
- 360 Degree Stereo Sound: These 2.0 channel stereo speakers deliver optimal stereo effects when properly positioned. For the best experience, separate the two speakers by approximately 1 meter, and position yourself 1 meter away from each speaker, forming an equilateral triangle.
- Wide Applicability: Equipped with a high-quality cable and independent drive-by-wire control for stable sound transmission and convenient operation. The 3.5mm audio interface ensures compatibility with most music players. USB power supply allows direct connection to a computer's USB port or most 5V chargers.

Maintenance
To ensure the longevity and optimal performance of your Sanyun SW102 speakers, follow these maintenance guidelines:
- Cleaning: Use a soft, dry cloth to wipe the exterior of the speakers. Do not use liquid cleaners or abrasive materials, as they may damage the finish or internal components.
- Storage: When not in use for extended periods, store the speakers in a cool, dry place, away from direct sunlight and extreme temperatures.
- Handling: Handle the speakers with care. Avoid dropping them or subjecting them to strong impacts.
- Cable Care: Do not bend or crimp the cables excessively. Always pull from the plug, not the cable, when disconnecting.
Troubleshooting
If you encounter issues with your Sanyun SW102 speakers, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Sound distortion or low volume | Insufficient power supply (current too low), especially from some computer USB ports (less than 1A). | Try connecting the USB power cable to a different power source, such as a 5V charger, ensuring the current is greater than 1A. |
| Continuous noise (humming/static) | Interference from the computer's power system when both audio and power cords are connected. | Ensure proper grounding of your computer. Try connecting the speakers to a different USB port or a separate 5V charger. Disconnect and reconnect cables. |
| Less or no bass | Underpowered speakers or potential damage to the bass diaphragm during transportation. | Verify the power supply is adequate (5V, >1A). If the issue persists, contact customer support for assistance, as the bass diaphragm might be damaged. |
If these solutions do not resolve the issue, please refer to the Customer Support section.
