With the e-bone cable guide, the problem of fastening the headphone cable in knots during transport as well as in use is a thing of the past. The whole expertise of the plastic expert igus® has been incorporated into the material of the e-bone. The cable guide is on the one hand light and elastic and on the other very rugged and stable. These characteristics and its flat and round design ensure a comfortable fit. An unintentional detachment of the cable from the guide is avoided by a simple fastening of both ends.
