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 maximise sound output and minimise 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 remote and mic are supported by all models of iPod, iPhone, and iPad (not all models support volume up/down functions). Audio is supported by all iPod models. Requires software version 1.0.3 for iPod nano (4th generation), 2.0.1 for iPod classic (120GB), and 2.2 or later for iPod touch (2nd generation).
