Quad-Driver Hybrid IEM

The Senfer EN900 IEM features two balanced-armature drivers and two dynamic drivers per ear. It’s built for durability, with a translucent plastic housing, a metal grid faceplate, and a shiny finish that’s particularly eye-catching. With a 16-ohm impedance, the EN900 can be easily driven by mobile sources, and its detachable MMCX cables make for easy replacement down the line. The Phonograph says, “Their premium sound, impeccable performance, fully packed features, and extremely affordable price (for a quad-driver earphone) make them one of our favorites. The Senfer EN900  can be safely recommended to anybody looking for a spectacular earphone." 

Note: At checkout, choose black, blue, or red.
