Versatile Connectivity Options

While the primary power source is USB, the SP‑U115 also offers a 3.5 mm stereo jack for direct audio input.

• Channel Configuration: Stereo (2.0 channels) – delivers balanced left/right audio for music and video.
• No Built‑In Amplifier or Equalizer: The speaker relies on the host device’s processing, allowing users to apply custom equalization if desired.

Ideal Use Cases

• Home Entertainment: Complements laptop or tablet playback for movies, music, and gaming.
• Travel Companion: USB power makes it perfect for use on planes, trains, or in hotel rooms where external outlets may be limited.

2. Connect the other end of the cable to a USB‑enabled device (computer, tablet, or power bank).
3. Turn on the speaker using the integrated switch.

Maintenance & Care Tips

• Keep the speaker away from liquids to prevent damage to the plastic housing.
