EP4s are available in small (S), medium (M), and large (L). Proper size is based on the dimensions of your ear's concha bowl. Size "medium" fits most people. For those with smaller (in diameter) ear canals, the two-flange stem of our EP3 Sonic Defenders may provide a better fit than the EP4's three-flange stem.
