Premium Fit Kit Includes Sound Isolating Sleeves The role of the included sound isolating sleeves is twofold: blocking ambient noise and ensuring a comfortable, customized fit. Because every ear is different, the Fit Kit includes three sizes (S, M, L) of the flex and black foam sleeves as well as 1 pair of triple flange and 1 pair of universal fit yellow foam sleeves. Experiment with the size and style that creates the best fit for you. A good seal is key to optimizing sound isolation and bass response as well as maximizing comfort during extended wear.
