Audio and Sound Equipment Design X-Boat Pro Earphones by Yuhang Chen X-Boat Pro is a pair of wireless earphones designed to be worn with one hand. The earphones slide out along rails on the charging case, so the case does not need to be opened. Users can hold the case near the ear and push an earphone directly into place. An open, hollow form keeps the earphones visible, which helps users check their status and reduces the risk of loss. The shape is inspired by the smooth lines of lotus petals. The case is made with vacuum silver die-casting and a tempered anti-glare glass back.
