The Apple EarPods with Remote and Mic are designed based on the geometry of the ear. The speakers have been engineered to minimize sound loss and maximize sound output. The Apple 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.
Compatibility
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.
Software Requirements
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).
