The Solekick™ Quick Charge True Wireless Earbuds features include Bluetooth® 5.0, Auto Pairing, and Auto Power-On. Once the earbuds are removed from the case, the earbuds power on and automatically sync to each other! The case also doubles as a power bank for your earbuds and can be charged with the included USB-A-to-Type-C cable. It only takes the case 30 minutes to charge the earbuds from 0% to 100%. The playback time of the earbuds is around 5 hours. Once the 400mAh battery of the case is charged, it will charge the earbuds 4x from 0-100%. The ergonomic design of the earbuds and silicone tips keeps them in place on the go. The earbuds have built-in music controls and dual microphones for hands-free operation. Simply press the music control button to turn on transparency mode.
