The Dual Flange Ear tip is an important milestone in the evolution of Etymotic. Traditionally three-flanged Etymotic ear tips have 3 potential contact points in the ear canal, thus they seal the ear canal really well. With the Dual Flange ear tips, a softer and more comfortable ear tip has been created that and isolates just as well as the traditional 3 flanged ear tips. The package contains 3 pairs (6 tips per package) of the selected size. These ear tips have an inner diameter of approximately 3 mm, so they can fit earphones and in-ear monitors of other brands. The outer diameter depends on the chosen tip size and can be 9, 10, 11 or 12 mm.
