Designed for demanding athletes and everyday listeners on the move, the Fitbit Flyer Wireless Headphone provides immersive sound quality with an ultra-secure fit that doesn't wander out of your ear when you're running, cycling, and working out. Gel ear tips engage securely without slipping out, even when you're sweating profusely and moving swiftly. These ear tips are customizable with numerous sizes available, plus they pair with interchangeable tips and wings for added security without them falling out. One of the coolest things about the Flyer Wireless Headphone is the Bluetooth 4. 2 pairing, which connects to two devices simultaneously, seeing many users are pairing with both tablets and phones. It'll seamlessly pair with the Fitbit Ionic, as well as other popular smartwatches on the market. For controlling tracks without digging through your pockets or pack, the three-button remote and dual mic allow you to pause and switch tracks, as well as take calls. The battery lasts up to six hours, so you can use them through longer workouts and commutes without it prematurely dying. Another cool feature, you can plug them in for only 15 minutes to gain an extra hour of listening time, which is nice when you only have limited charging time.
