Create an ethereal illustration of a character with long, flowing hair that has a pastel and iridescent color palette. The character should be wearing large, stylish headphones, surrounded by a dreamy background filled with soft colors and musical notes floating around. The overall atmosphere should convey a sense of tranquility and creativity, with a blend of light and sparkles that enhance the magical feel of the scene. Focus on the delicate details in the hair and the shimmering effects to create a whimsical, enchanting vibe.
