With the advancement of society, the range of applications for earphones is expanding, and they are widely used in office environments and all kinds of places for listening to music or enjoying entertainment.

The main objective of this application is to propose earphones that enhance wearing comfort and improve the user experience. To achieve the above objective, this application provides an earphone comprising a main body, a connecting part, and a curved part. The main body includes a sound-producing segment and an extension segment, one end of the extension segment is connected to the sound-producing segment, the other end of the extension segment curves toward a curved portion and is connected in a transitional manner, one end of the sound-producing segment is connected to the extension segment, the other end of the sound-producing segment is a second free end, and in the worn state, the extension segment curves and extends from the front side of the ear portion toward the rear side of the ear portion via the upper edge of the ear portion, forming a first contact position with the upper edge of the ear portion. The connecting part is used to connect the main body and the curved part. When worn, the connecting part is located between the back of the ear and the head, and extends from top to bottom, curving along the back of the ear. One end of the curved portion is connected to the connecting portion, and the other end is a first free end.
