GravaStar, a company known for its unique Sci-Fi-Inspired Hi-Fi audio products, is launching its Sirius P5 today.

New Sci-Fi Earbuds

The company’s new earbuds and cases combine hyper-modern creativity, high functionality, and customization with mecha-inspired designs. This new lightweight product is also the first to offer interchangeable charging cases.

Each case holds four extra charges. Combined with the eight-hour battery life on the earbuds, users get up to 40 hours of playtime.

The Sirius P5 has three unique industrial designs, all inspired by Sci-Fi and available right now:

  • Defense Armor
  • Defense Mecha
  • Crystal Blue

According to information from the manufacturer, more styles are on the way.

Users can purchase different cases without having to also buy new earbuds. All cases feature four RGB lights that can be customized with changing colors for extra personalization.

“Sirius P5 is unique in that we took inspiration from the iconic retro lighters that allow users to collect and change their cases while adding protection. We’ll continue to release new designs so people can have fun expressing their style while vibing to their music,” said Yong Huang, the founder and industrial designer at GravaStar.

Each bud weighs only five grams and feels comfortable in the ear. Users can also attach the earbuds to an included necklace that ensures they are never lost during any activity.

The Sirius P5 features the latest Qualcomm 3046 chip and Bluetooth 5.2, ensuring a fast and stable connection. The 12mm drivers can cover a wide range of frequencies, resulting in high volume and deep bass. All that while using less power.

GravaStar has combined the futuristic design with easy-to-use features. One example is the smart touch controls you can use to jump between calls and music, control the volume, switch between tracks, activate Siri, and more.
