The ES WW is used for balanced transmission of stereo signals, for example from a laptop to the stereo jack input of a recording device.

The conductor area of 2x 0.14 mm² and shielding of twisted copper strands (95% coverage) ensure unaltered signal transmission. The single-strand construction (18 x 0.10 mm) and the robust but flexible PVC sheathing compound ensure good wind ability and durability. The two 3.5 mm stereo jacks (mini jacks) protect the soldered joints with molded-on anti-kink sleeves and thus allow high plugging cycles.
