Good, unstoppable music Equipped with a powerful battery, the Bravo B1 stays longer with you – 38 hours of music and 500 hours in standby mode. 13.6mm dynamic speaker, deep bass Generated by a 13.6mm dynamic speaker, the Bravo B1 delivers a clear voice and strong bass that exceeds your expectations, delivering a pure hearing experience. Fast and stable With BT V5.0, the transmission would be faster and more stable thanks to a strong resistance to ants and a low energy consumption, for smoother calls and a smoother music playing time. Magnetic design, premium quality Bravo B1 uses one type of magnet, not only light and separable, but also easily attached when not in use, effectively avoiding frequent winding and knotting of threads. The metal craftsmanship considerably increases the hardness of the surface, leaving less external scratches. Higher anti-corrosion contributes to a longer service life.
