Its original SportClip® design ensures the clips stay secure on the ear while the in-ear ported design provides an effective acoustic seal for clear sound. The in-line one touch microphone allows for convenient hands-free communication. These ear clips feature a sweat-resistant coating and come with three sizes of ear cushions to accommodate different fit preferences.
