The Supernova Bluetooth Speaker has crash-landed, and is now our go-to speaker for everything from pool parties to game nights.

Gravastar’s new portable speakers sound like they’re ripped straight out Portal. The unique design of this powerful speaker will turn heads.

What’s in the box

Inside the box, you’ll find the instruction manual, a USB-A to USB-C charger, an aux cord, and a handle. The handle has accessories to attach it to the speaker.

Everything in the box is protected by styrofoam. The charger and aux cord are long enough that the speaker is comfortable to use.

Those planning to use an aux cord with their iPhone should have a lightning cable adapter or lightning cable aux cord ready to connect their phones. But, if you plan to use only Bluetooth, this shouldn’t be a problem.

A power brick is not included, so make sure you have that if you plan to use one to charge the speaker.


The sci-fi vibe of this speaker is different from all other speakers on the market. In addition, it comes in two different colors, matt black and dawn white.

The speaker is made of zinc alloy, it gives weight and makes it durable. Its metallic casing makes it look more like an alien spaceship.

The lantern in the middle has different modes. Users can choose to use it in dynamic light mode, which slowly cycles through all eight available colors; single color mode, which makes it a static color; or camping light mode, which simulates the light of a campfire.

The lantern adds beautiful ambient light to any room. We wouldn’t rely on it as our only source of light in a dark cave, but it makes a nice night light when you’re ready to sleep.

If you’re looking for a speaker to rock, this is the one for you. We made many of our friends jealous when we tried it at a small get together. Everyone loved it and we kept asking where we got it.

Be careful – this speaker is adorable. You might just have an emotional attachment to it and want to take it with you wherever you go. In fact, we named our B-Max, and it’s our little travel companion now.

Sound quality

This speaker will fill any room with music. The sound comes out clear, and the bass will rumble through any table you place it on.

The speaker is small but loud. It delivers high quality sound and the sounds are clear and crisp no matter what genre you choose to play.

Music with more bass is best and highlights what this kid can do. That’s not to say that more upbeat songs, like “Son Amores” featuring Los Macorinos and covered by Natalie Lafourcade, don’t sound good. But songs like “New Magic Wand” by Tyler, the Creator or “Titi Me Pregunto” by Bad Bunny take full advantage of the Supernova’s bass.

This speaker allows you to experience every part of a song without compromising anything. The sound is rich, clear, and crisp.

According to their website, two Supernovas can be connected to enhance your listening and amplify your music experience. Unfortunately, we only received one to review, so we don’t know how well it works.

This is the speaker you bring to a pool party, picnic, or to add ambiance to a round of Dungeon and Dragons. It’s easy to carry and durable enough to be your go-to whenever you need music.


This speaker is almost perfect. almost.

The battery lasts seven hours when used at 60% volume, but it takes three hours to fully charge. This is not a dealbreaker at all. But, if you forget to charge your devices, this is something to consider.

The amount of time it takes to charge is a fair trade for the impressive speaker quality. It’s not a hassle if you plan to use it indoors or near wall outlets.

Bring a portable charger if you’re worried about the speaker running out of juice. It may not be convenient, but the battery lasts so long that you probably won’t need it.

Final thoughts

It’s everything you want in a speaker. It’s durable, sounds great, and it’s portable. Plus, its unique aesthetic will get you lots of compliments. This speaker is out of this world.

The speaker allows you to immerse yourself in the music completely. Despite the size, the small speaker is loud and will fill any space with the sounds of your favorite musical artists. The high notes are crisp, and you can feel the rumble of the bass.

Built-in lighting can be customized to bring great ambiance to any setting. Whether you decide to keep it as a decoration next to your gaming consoles or as a nightlight on your nightstand, it will fit in wherever you put it.
