A headphone case with the texture of AirPods is placed at a 45-degree angle, with the lid open, revealing four cartoon characters inside. From left to right, the first is Tang Seng, dressed in a red robe, wearing a Pilu hat, with a compassionate expression and slightly closed eyes, as if reciting scriptures; the second is Sun Wukong, wearing a golden headband and a tiger skin skirt, with bright, piercing eyes and a confident smile, one hand resting on his forehead as if looking into the distance; the third is Zhu Bajie, with a round face and big ears, dressed in black clothing, exposing his chest, with a silly and endearing expression, grinning widely; the far right is Sha Seng, sporting a beard, wearing a crescent-shaped headpiece and blue clothing, with a simple and honest expression. They are all shown from the waist up, with their heads visible. The headphone case has a simple design, with a white exterior featuring two circular grooves at the opening, and the front is decorated with the head of the white dragon horse, with bright eyes and flowing mane, along with a circular button and a green indicator light below. The light-colored background makes the main subjects stand out more, and the overall image is filled with the charm of mythological stories.
