GO Air Sport features 8+ hours of playtime in each earbud and 24+ extra hours from the charging case (32+ hours total). Return to the case to recharge the buds, and use the integrated USB cable to charge the case. An IP55 sweat resistance holds up against sweat and dirt, so hit the trails, the gym and more. The ergonomic earhook fits even the smallest ears and stay securely and comfortably in place. Try all sizes of the gel tips to get a secure fit and just GO. Use either earbud independently or use both together. A built-in MEMS microphone in each bud ensures clear calls. With just a few taps via touch sensors, you can choose your sound preference: JLab Signature, Balanced and Bass Boost modes – without an app. Enjoy volume and track controls, plus play/pause, answering calls and activating your smart assistant with the touch control functions.
