Abstract
A headphone device having a headband assembly worn on the head and a headphone main body attached to one end of the headband assembly. The headphone device is provided with an ear device that prevents slipping when worn and stabilizes wearability. The headphone main body is attached to the headband assembly in a rotatable manner so that the axis of rotation may be inclined with the center line of the headphone main body. The headphone main body can be matched to the inclination of the ear and the headphone device has stabilized wearability, improved sound quality, and improved comfort when worn.
