OUR PART # EATFL1-6
3-pair package of triple flange sleeves for Shure E3c, E4c, E5c, E500, i3c, and i4c earphones. The comfortable silicone sleeves are washable and reusable. The triple flange sleeves form a tighter seal than Shure's flex sleeves, helping to block out more ambient noise. The tube (flange) of the sleeve can be trimmed for a better fit.
