Unlike traditional, circular earbuds, the design of the EarPods 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 the EarPods have been engineered to maximize sound output and minimize sound loss, which means you get high-quality audio. The EarPods also include a built-in 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. The Lightning to 3.5 mm Headphone Jack Adapter lets you connect devices that use a standard 3.5 mm audio plug — like headphones or speakers — to your Lightning devices.
