With the e-bone cable guide, the problem of knotted headphone cables during transportation, and whilst in use, is a thing of the past. The plastics manufacturer igus has ensured that the material of the cable guide is light and at the same time elastic, yet very durable. These properties together with a flat, rounded design guarantee a high wearing comfort. An unintentional detachment of the cable from the guide is avoided by a simple fastening of both ends.
