Case Design

The case and pods feature a mecha-futuristic design and a weathered airbrush effect giving the product an overall sci-fi-industrial aesthetic.

The charging case is a sturdy weighted affair that also comes with a solid chain that can be easily attached making the case a fashionable wearable. The case is made from a zinc alloy and features 6 RGB lights and most importantly : a functional bottle opener built-in!

The battery gives around 4 hours of continuous playtime and has 3 extra charges in the case which means you can comfortably keep listening when not near a power supply.

It’s worth noting that unlike the buds themselves, the case lacks an IP rating, so it should be kept away from liquid and wet earpieces.

Earbud Design

The Sirius Pro earbuds feature in-ear detection and utilise 7.2mm dynamic drivers and four Knowles-balanced armatures. What this means is that the sound has been designed by specific audio boffins!

The buds have an IPX5 rating for durability and each earbud weighs only 6 grams, meaning they’re not cumbersome to wear. The soft silicone ear tips are included with 3 sizes (small, medium and large) and help in blocking out unwanted noise by forming to your ear shape.

Each earbud features the Gravastar G logo and doubles as a touch-sensitive control panel and is easily accessible. Tap once : play or pause music, or accept/end call. Double tap : forward (right earbud) and backward (left earbud) track. Triple tap (right earbud) : toggles between the Music and Gaming latency modes. Triple tap (left earbud) : switches between modes. Long press 1.5 sec (right earbud) : increase volume. Long press 1.5 sec (left earbud) decrease volume. Quadruple tap (either earbud) : activates device voice assistant.

GravaStar has their own exclusive DSP audio algorithms that “offer an immersive, crisp experience through Bluetooth 5.2 True Wireless Stereo”. The Bluetooth signal is stable and works at a good distance from the device.

The earbuds offer 3D surround sound and most notably, 3 custom modes:

  • The Gaming Mode is ideal for Battle Royale gaming and enables the gamer to pinpoint the direction of incoming fire or enemy’s movements with 5.1 virtual surround sound.
  • The Movie Mode grants a full cinematic experience with HD surround sound and offers balanced stereo EQ, ideal for Michael Bay fuelled action epics.
  • The Music Mode ensures clear, natural vocals and a deeper bass balancing ensuring the best overall listening experience especially with live/concert tracks.

With regards to calls, there is noise cancellation at work here and for the most part cuts out background noise accurately. The voice signal is crisp and clean.

Gravastar Sirius Pro Gaming Earbuds price


The staggering sci fi design of these earbuds is a real selling factor for me. Obviously the most important factors should always be sound and comfort but this attention-to-detail design really floats my boat.

Gravastar are known for making products that look very cool and this is another prime example of that wheelhouse. Even the presentation of the case was an experience to behold. (For example, when charging the RGB light on the case pulses as if breathing which is a beautiful touch.)

A decent set of earbuds, beautifully presented and sturdy AF. My main gripe is the price point, but given the durability of these earbuds that could be overlooked.

A fantastic set of earbuds for gaming which i’ll be specifically pairing with my Meta Quest 2 setup.


Born in 2018, Gravastar are a team of designers, engineers, gamers, music fans, explorers, and visionaries with a firm vision to create futuristic products that blend sci-fi with hi-fi. Their audio products are essentially collectibles that take inspiration from classics such as Transformers, Gundam, and Star Wars but remain staggeringly original and wonderfully functional.


You can pick up a set of these mecha-futuristic earbuds from the Gravastar website and all major audio stockists for around $149.95 (£125 GBP) and are available in four colors, including Neon Green, Space Gray, War-Torn Grey, or War-Torn Yellow.
