The EarPods design replaced a previous Apple headphone design with a circular earphone design. The product description states that, “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.”
EarPods also included a remote and microphone on the right EarPod wire. The remote allowed the user to pinch the thickened cord to control volume, play/pause music and video, and answer or end a call.
The same wired EarPod design was used in the EarPods with Lightning Connector product when Apple removed the audio connector from the iPhone. Both the 3.5 mm Headphone Plug and Lightning Connector options were sold at the same time since both ports were still used in Apple products.
This product was sold in a variety of packaging. This is the same packaging that shipped inside iPhone models and also available as OEM replacement parts from some online retailers.
