Gravastar Sirius Review: The Mecha Gamer Earbuds

Like all other Gravastar products, Sirius earbuds have this futuristic, mecha design that just blows everything else out of the water.  As far as controls and indicators, these are delegated to the earbuds themselves with the case simply having a type-C charging port, a reset button, and a small LED that will let you know if it’s fully charged. 

Even more attention here was given to the build quality of the case as it’s entirely made out of zinc alloy which makes it pretty heavy despite its relatively small size. This is complemented by the mechanism holding the earbuds in place with this little button here requiring a surprising amount of force to spring open. Even after that – the earbuds are further held in place by some really strong magnets that won’t make them budge even with violent shaking. 

The earbuds themselves follow the visual aesthetic of the case with some cool little design details. Each also has a small LED that will light up when the earbuds are charging or pairing with Bluetooth devices. The earbuds feature the always welcome touch controls so you can tap or hold each to play or pause music, skip tracks, control the volume, activate Siri or the Google assistant, and take or end calls. They are also IPX5 rated so splashes of water should pose no issues. 

Sirius uses Bluetooth 5.2 and pairs them up with SBC and AAC codecs. Thanks to this, you get a rock solid connection to paired devices, a decent range, and very low latency. The 7.2 mm dynamic drivers here deliver a surprisingly great sound with emphasis on punchy bass. This isn’t surprising seeing as they are aimed toward gamers but it pays dividends for listening to music as well.The case holds enough juice to charge the earbuds 3 times but the earbuds themselves will last you only around 4 hours without ANC which is weaker than many competitors in the same price range.
