Who the GravaStar Sirius Plus is for

  • Workouts: GravaStar rates the earbuds IPX4 against sweat and light rain.
  • Long days: Up to 7 hours per charge plus 21 hours from the case adds up to 28 hours, and a full recharge takes about 1.5 hours.
  • Standout style: The Sirius Plus adds customizable RGB ambient lighting and comes in Black or a hand-finished War-Damaged Yellow special edition.
  • Skip it if: You use an iPhone and want app control, since GravaStar's Sirius Plus app is Android-only.
