This ear-hung earphone reconstructs the wearing experience by precise modeling of body engineering. The arc-shaped ear-hung earphone fits the natural curve of the auricle. The lightweight skin-friendly silicone material is soft and does not press the ear, and there is no burden for long-term wearing. Innovative and adjustable ear hook design, suitable for different auricle shapes, stable fit without falling off during running, riding and commuting, and seamless switching between sports and daily scenes.
