Built for real movement, the Sudio B5 features an open-ear design that lets you enjoy your music while staying aware of your surroundings. With an IPX7 water-resistance rating, it’s made to handle intense workouts, heavy rain, and everything in between. Intuitive tactile buttons make it easy to control your audio on the move, while the flexible, secure fit and up to 12 hours of battery life keep you comfortable through every run and routine. IPX7 water resistance means the headphones can withstand immersion in water up to 1 meter for up to 30 minutes. They easily handle heavy rain, sweat, showers, and even short swims in a pool or lake.
