Once removed from their charging case, the earbuds automatically power on and pair to each other, providing up to four hours of playback at max volume. Built-in touch controls let you answer or end a call by simply tapping either earbud. The built-in microphones allow for crystal clear calls. The charging case will fully charge the earbuds five times before needing to be recharged itself. It takes 1.5 hours to charge the earbuds and 2.5 hours to charge the case. Includes type-C charging cable plus small, medium and large ear tips.
