Unlike traditional, circular earbuds, the design of the iPhone Earphones is defined by the geometry of the ear. Which makes them more comfortable for more people than any other earbud-style headphones.
The speakers inside have been engineered to maximize sound output and minimize sound loss, which means you get high-quality audio.
iPhone Earphones also include a built-in Mic and Remote that lets you adjust the volume, control the playback of music and video, and answer or end calls with a pinch of the cord.
