Note : If the size of the earbud tips does not match the size of your ear canals or the headset is not worn properly in your ears, you may not obtain the correct sound qualities or call performance. Change the earbud tips to ones that fit more snugly in your ear 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 with lightning connector 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 Works with all devices that have a lightning connector and support iOS 10 or later, including iPod touch, iPad, and iPhone
