Unlike traditional circular earbuds, the design of the EarPods follows the geometry of the ear. This makes them more comfortable than any other earbud of this type for a larger number of people. The speakers inside the EarPods have been engineered to maximize sound output and minimize sound loss, which means you get high-quality audio. The EarPods with 3.5 mm jack include a 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.
