What customers like about Gravastar Supernova

  • Striking, mecha-inspired futuristic sci-fi design that serves as a decorative conversation piece.
  • Excellent build quality with a sturdy, premium zinc alloy metal frame.
  • Loud and surprisingly powerful audio for its compact size, capable of easily filling a room.
  • Clear, crisp high-end frequencies and well-separated vocals that do not muddy easily.
  • Versatile ambient RGB lighting modes, including a useful campfire/lantern flickering effect.
  • Stable and rapid wireless connectivity powered by Bluetooth 5.3.
  • Includes a convenient, removable zinc alloy carrying handle for added portability.
  • Supports True Wireless Stereo (TWS) pairing to link two units together.

What customers don't like about Gravastar Supernova

  • Premium price tag makes it a costly novelty item compared to traditional Bluetooth speakers.
  • Bass lacks a deep, sub-bass thump and can be slightly underwhelming for heavy-bass enthusiasts.
  • Audio definition loses clarity and can become muddy or distorted when pushed to maximum volume.
  • Downward-firing driver design means the audio profile heavily depends on and bounces off the surface it is placed on.
  • Lacks a dedicated mobile app for custom equalizer (EQ) tuning and advanced light customisation.
  • The unskippable sci-fi power-on/off sound effects can become repetitive and annoying over time.
  • The central ambient lantern light could be brighter for practical outdoor illumination.
  • Charging time is relatively slow, taking around 3 hours to fully replenish the battery.

Verdict

The GravaStar Supernova is a mecha-inspired portable Bluetooth 5.3 speaker built from a durable zinc alloy chassis, weighing 3.1 lbs, and featuring adjustable, foldable legs alongside an integrated carrying handle. It features a 25W audio configuration comprised of a 3-inch full-range driver and a 0.5-inch precision tweeter that deliver crisp highs and deep bass with a frequency range of 60 Hz to 20 kHz. Main advantages include its highly unique sci-fi aesthetic, solid structural durability, room-filling sound with True Wireless Stereo (TWS) dual-speaker pairing, and an ambient light setup offering 3 modes across 8 colors, mimicking a camping lantern. However, notable drawbacks include its lack of physical track navigation controls on the device, the absence of a dedicated companion app for EQ adjustments, and its somewhat directional audio profile rather than a true 360-degree soundstage.
