For E2, I2, and QuietSpot Versions. These reusable, disposable foam sleeves compress to fit gently into the ear. Once in the ear, the foam expands to form a tight yet comfortable seal that holds the earphones firmly in place. The E2c/E2g/i2c earphones and QuietSpot Headsets come with three sizes of orange foam sleeves to choose from (small, medium, large) for the best personal fit.
