Surging Sound The embedded cutting-edge integrated dual-magnetic circuit design of the 1MORE PurePower Driver increases sensitivity to reproduce the subtle nuances of sound. Innovatve directional sound loops designed with a skin-frendly silicone material elevate comfort.Conducting sound directionally decreases the leakage to achieve a more vivid listening experience and better privacy. 4 high-performance MEMS microphones and an Al-powered deep neural network (DNN) algorithm accurately pick up the human voice and eliminate background noise by up to 30 dB,even in bustling crowds,the two-way calls are still clear. Raise Situational Awareness An Open-air design of S50 open earbuds doesn't block the environmental sound that is around you,allowing you to hear the peripheral sound of cars,and crowds when you are cycling.running.or walking to increase awareness and safety.
