Gravastar Mars Pro Bluetooth Speaker Review: Be Ready to Love the Invasion

Gravastar Mars Pro Bluetooth®Speaker Review

Bluetooth speakers come in all shapes and sizes. I’ve reviewed star ships, cubes, police boxes, and columns. The Gravastar Mars Pro Bluetooth® Speaker, however, sets a new standard in workmanship and sound. The mecha-robot-inspired design looks like it landed directly from the pages of a Robert Heinlein novel, bounded from a screening of Alien, or crawled out of frame from a manga book being consumed on an Amazon Kindle.

The $229 and up Gravastar Mars Pro Bluetooth Speakers are not cheap, nor are they light. But they are fun, intriguing and very good to listen to.

What we like

Pros

• Looks amazing
• Sounds amazing
• Long battery life
• USB-C acts as auxiliary input
• Becomes stereo in pairs

The $229 Gravastar Mars Pro Bluetooth Speaker is not a device that warrants a staid, non-emotional review. This mecha-inspired robot is equally amusing and terrorizing. It may be a friendly companion, or it may be the forward guard of a mechanized invasion force. The white review unit looks more like a robotic family pet, one perhaps possessed by the spirit of a Barbie dog, especially when sporting its pink and blue flashing lights and pouring out Dua Lipa’s “Dance the Night.”

The sound is outstanding—and plenty loud. Gravastar shared that the speaker was tuned by Gates, an international acoustic master. As they claim, it does offer deep base, even at low volumes. The rear leg of the speaker can be pointed at a surface to create more resonance and Digital Signal Processing (DSP) shapes the sound.

Each speaker includes two subwoofers and two tweeters. The treble is pleasant and clear, and the bass is rich and structured.

As for power, well, that also seems to come from a robotic future. It runs for up to 15 hours on a battery borrowed from electric vehicles. The company claims over a thousand charging cycles, over 3 times the average rechargeable speaker.

The functions are fun, too. Six dynamic LED light options create a mood. And volume control, given the pet analogy, is controlled by touch, similar to stroking a cat between the eyes.

Pair two speakers via Bluetooth® 5.2, and the pair transforms into stereo. We were not able to test this feature. I can imagine, though, that those who want to create a truly unique experience may want to buy more than one type of Mars Pro for variety. See the gallery for Mars Pros options.

Sustainability is average with a fancy retail box and sculpted Styrofoam (with recycling icons imprinted) and a plastic retail handle.

What could be improved

Cons

• It doesn’t move
• Heavy

When we have guests over, the Gravastar Mars Pro usually makes an appearance. The lights flash, the music booms, and they want to see it move. It looks like it should move, but it doesn’t. It’s a speaker, not a real robot. When they insist, I bring my Star Trek phaser and tell them that I stunned it and that crippled its mobility.

The Gravaster Mars Pro Bluetooth Speaker is portable in size. But this isn’t the tiny JBL Go 3 that will just get tossed into a bag unnoticed until it’s time to perform. This is a hefty speaker with appendages. It’s made of zinc alloy, and it weighs almost three pounds. Heavy isn’t really a con unless owners expect to carry the Mars Pro in a backpack along with a laptop and tablet. Then it’s bulky and heavy, but that may be forgotten, like childbirth, when people start partying around the little robot.

Gravastar Mars Pro Bluetooth Speaker: The bottom line

Gravastar continues to create great-sounding audio devices with unique, science-fiction-inspired styling. Gravastar Mars Pro Bluetooth Speaker is as fun as it is functional.
