Headphones go through a lot of wear and tear; especially in schools; which is what we had in mind whilst designing our headphones; instead of throwing out pair of good headphones because of a damaged lead you can purchase our replacement lead. This replacement lead is 1.2m long and has 2 3.5mm jacks; one side has a screw in port and the other has a snap in port. Designed to be used with our class headphones and also our wireless headphones 6.3mm adaptor not included.
