The Skullcandy Dime 2 True Wireless Earbuds provide up to 12 hours of playback (3.5 hours from the earbuds plus another 8.5 from the charging case). The small, efficient battery of the Dime makes its carbon footprint less than half that of other earbuds. Both earbuds contain the Tile finding technology, so if you ever misplace one, you can just "ring" it from the Tile spp. The earbuds are IPX4 Water-Resistant and include built-in microphones and music controls. Charge Time: Earbuds 1 hour and Charging Case: 2.5 hours.
