For those unfamiliar with the brand, Gravastar is a China-based company that prides itself in developing unique-looking smart accessories, although the brand mostly specializes in audio hardware. As such, Gravastarâs Sirius Pro earbuds certainly take a different approach in terms of looks, but is the actual performance of the earbuds something truly out of this world? Letâs take a look.

Unboxing Experience
Gravastar has gone to great lengths to provide users with a pretty unique unboxing experience. The earbuds and charging case come in a plastic box thatâs made to look like a cargo container of sorts, and this also holds a smaller, separate box for your accessories, as well as paperwork.
Thereâs a set of extra eartips that can be easily swapped out for a better fit, a USB power cable for the charging case, and a small chain that lets you attach the earbud case to a backpack or holster of sorts. Unique design aside, itâs a pretty standard package, with everything you need to get started.
Design and Controls
As mentioned earlier, one of the first things that stands out the most about the Sirius Pro earbuds is the rather striking design. Like other Gravastar products, the earbuds were clearly made with a sci-fi design aesthetic in mind, and itâs this unique approach that sets them apart from more ânormalâ looking wireless earbuds, at least as far as appearances go.
While the charging case is made out of metal, the earbuds themselves are made out of plastic, although they do have an IPX5 rating, so they should be safe from light splashes and rain.
As for the charging case, itâs no secret that Gravastar took a lot of inspiration from mechanical and cyberpunk elements in designing the case, which the company says is made from a Zinc Alloy material. It is a bit heavy though, especially when comparing it to other wireless earbud cases that are made out of plastic. On the other hand, itâs a nice durability that you donât see much of in mainstream products.
The case cover is pretty much an open design that snaps open with a press of the button on the side. It also features RGB lighting near the bottom, which also doubles as a charging indicator. The bottom of the case features a USB Type-C charging port, as well as a switch that allows users to reset the earbuds. Additionally, the button can also be used to control the built-in RGB lighting on the charging case.
The Sirius Pros have a nice fit in general, although I should say that the earbuds are a bit on the large side, so you might want to swap out the eartips for a better fit in case theyâre too large for your ears. As for controls, the earbuds do respond to tap controls, which can be used to play and pause media, as well as volume adjustment.
It should be said that the earbuds are a bit sensitive to touch, so there were moments when I did have unwanted feedback due to accidentally touching them with my hand, which the earbuds sensed as a full tap. This wasnât always the case though, but Iâd recommend being careful whenever your hand is near the earbuds just to be sure.
Sound Quality
The Gravastar Sirius Pros pack 7.2mm dynamic Drivers inside, and users also get additional features including environmental noise cancellation (ENC), built-in wear detection, as well as Knowles Balanced Armature, which Gravastar says is specially designed to get the best-sounding quality possible. According to the company, the earbuds have a low latency of 65ms, which more or less was accurate, at least in my usage.
Sound quality was pretty decent – the Sirius Pros manage to do a good job, with a rather competent bass sound. Tracks with heavy bass (such as metal and rap) did sound good in my experience, which was able to last around four hours of playback time (sixteen hours with charging top-ups). The ENC performance was serviceable, although personally I would have preferred proper active noise cancellation (ANC) integration with the earbuds. With that being said however, I was able to hear less of the noise around my immediate surroundings, which was a nice feature to have.
There are also other features including Movie mode and Gaming mode, although youâll need to access these manually via tap controls as thereâs no software shortcut app with the Sirius Pros. One thing to note though is that I did prefer the sound quality WITHOUT the addition of Movie or Gaming mode, as I did notice a drop in sound quality whenever I had these on. Youâd best stick to the default modes for a better listening experience.
Of course, there are built-in microphones with the earbuds that let you use them for voice and video calls. Communication through the mics on the earbuds was pretty decent, although during a voice call, my call recipient did note that my voice sounded a bit on the tinny side during the call.
So are they worth it?
In terms of cost, the Gravastar Sirius Pros are priced at around $150 on Gravastarâs website, although you can occasionally get them for around $100 with sales or from other online retailers. For the price, you do get a great design, solid build quality, as well as decent sound quality. On the other hand, there are some factors to consider, such as the lack of active noise cancellation, more in-depth tuning and EQ profiles, especially when compared to other competing devices from budget-friendly brands like Soundcore and 1More.
However, if features such as these arenât an impedance to your enjoyment, and the design is something youâd really love to get your hands on, then by all means go out and get these earbuds for yourself.
