What customers like about Energy Sistem Urban Box Supernova

  • Good value for money with reasonable audio performance for its price point.
  • Compact and lightweight cylindrical chassis making it highly portable.
  • Versatile multi-source connectivity including Bluetooth, USB, microSD card, and 3.5mm AUX input.
  • Visually appealing aesthetic design featuring customizable RGB LED light sequences.
  • Sturdy build quality with an IPX4 splash-proof fabric coating suitable for outdoor use.
  • Capable of pairing with another unit via True Wireless Stereo to double the audio output.

What customers don't like about Energy Sistem Urban Box Supernova

  • Disappointing real-world battery life that often falls significantly short of the advertised 12 hours when the RGB lights are active.
  • Sound output lacks depth and can feel underpowered or flat at higher volumes.
  • Absence of a dedicated battery level indicator on the physical body of the speaker.
  • Occasional quality control issues reported with battery charging functionality out of the box.

Verdict

The Energy Sistem Urban Box Supernova is a 16W stereo 2.0 portable wireless speaker featuring dual 40mm full-range drivers and a double membrane passive radiator for bass amplification. Key advantages include its flexible audio sources supporting Bluetooth 5.1, True Wireless Stereo pairing, a 3.5mm auxiliary input, and MP3/WAV playback via USB or microSD cards up to 64GB, all encased in an IPX4 splash-proof fabric with customizable RGB LED lighting and a 2000 mAh battery offering up to 7 to 12 hours of playback. However, its downsides include an overall volume output that remains relatively low for outdoor parties, lack of customizable individual solid colors for the RGB lighting modes, and noticeably weak bass depth compared to other speakers in its class.
