Big sound in small form-factor. These earbuds with C-bridge design deliver sterling sound quality and clear vocals within a tiny, delicate body thanks to the 10.8 mm dual-magnet high-sensitivity driver unit. Enjoy crystal-clear calls with a delicate microphone system that works in tandem with a multi-channel deep neural network (DNN) algorithm to effectively pick out voices from ambient noises, it also provides direct sound as leakage is minimized by a sophisticated reverse sound waves system built inside the acoustic ball, meaning sounds are transmitted precisely into ear canal, making for a private listening experience
