Description:<br> Bone Conduction headphone is specially designed for exercising, running, cycling, hiking or just work in the office. While you are listening to music, you are able to hear your surroundings, preventing potential danger in outdoors. Since this earphone uses bone technology, the sound quality is not one of its prominent features.
