GravaStar definitely wins the award for most unique earbuds I’ve ever reviewed. Their futuristic headphones and bluetooth speakers are guaranteed conversation starters.
The Gravastar Sirius Pro TWS ($84 USD) came in a unique shrink wrapped metallic looking windowed box with the earbud’s charging case proudly on display. The box serves as both retail packaging as well as device storage when the headphones are not in use. Its padded case also includes a black box containing eartips, a small manual, an even smaller USB-C charging cable and a black lanyard chain. Along with the space gray model that I was sent, GravaStar also offers green and matte black as well as yellow and gray “war-damaged” models ($97 USD) featuring a relic, aged effect.
Right off the bat, The futuristic, funky “space-junk” looking Zinc-alloy charging case has some real heft. Pushing the black button on the right side releases the metal frame that allows you to access the earbuds. A tiny little LED on each earbud pulses softly denoting power. Another LED built into the case can be turned on by pushing the button on the bottom next to the USB-C charging port to cycle through 6 colors.
Removing the earbuds from the case automatically powers them on and that can be a little tricky as there is very little of the earbuds exposed from the case to allow my fingers to grip each earbud. Pairing them (Bluetooth 5.2) is done quickly by removing them from their case and visiting your phone’s bluetooth settings.
While the Sirius Pro’s charging case has some serious weight, the earbuds themselves don’t. They don’t bother my ears and with the proper fitting silicone eartips, sit comfortably without dangling out. While I probably wouldn’t go running with these, they are IPX5 water resistant and would definitely withstand a bit of moisture. The IPX5 designation indicates that a device should be able to survive 15 minutes under a jet of water (at a rate of 12.5 liters per minute at a pressure of 30 kilopascals from a distance of 3 meters). While the IPX5 certification suggests that a device will survive heavy rain with ease, the included manual warns not to use the Sirius Pro earbuds in the shower, under rain or in the washing machine. This was not tested.
With balanced Knowle armatures and 7.2mm hybrid dynamic drivers, the Gravastar Sirius Pro earbuds are efficient and capable. I found the three sound profiles (Movie/Music/Gaming) to be effective at simulating effects for each environment. Movie Mode simulates a cinematic effect with some surround sound processing while Music Mode enhances highs and lows to clarify vocals. I found Music Mode to be a little lacking in mid-tones and without a customizable EQ, there is no way to change this. Gaming Mode provides a lower latency of 65ms and also offers a 5.1 virtual surround sound mode that does okay, but does sacrifice some sound quality for lower latency.
Battery life is where the Gravastar Sirius Pro take a hit. At only 4 hours per charge, you’re going to have to take some breaks on an all night gaming session. On the flip side, if you plan on enjoying a beverage of the bottled variety during your lengthy gaming session, the Gravastar Sirius Pro charging case doubles as a bottle opener!
At sub one hundred dollar price point, aimed specifically at the gamer audience, the Gravastar Sirius Pro do a great job at providing solid in-game audio without breaking the bank. The cool design esthetics, LED lighting and various color options make them a great gift for your favorite gamer.
