We engineered our Wireless Earbuds on the Bluetooth 5.2 platform, allowing our Spire Wireless Earbuds to communicate as Bluetooth Low Energy devices, providing longer battery life for the listener and a stronger signal for better stability. Our Wireless Headphones are constructed with custom tuned Neodymium Drivers to provide hours of listening enjoyment, with balanced immersive sound. Spire Wireless Earbuds are built to last for up to 4 hours of use on a single charge. The Charging Case provides an additional 300 mAh of charging power to allow for a total usage time of up to 20 hours. One Touch Media Controls provide total control of your Music, Videos and Media with the touch of a single earbud, on either side in one tap or multiple taps depending on the function you want performed. Perhaps, most importantly we designed our Bluetooth Earbuds to be impervious to Rain and Sweat so you can focus on your workout. Great for Running, Gym, Hiking, Biking, Workouts, Cross-fit, and Yoga.
