Unlike earsets that are hard-wired from the mic to the connector, this cable from Countryman will quickly and securely snap into the E2 Earset to link the mic to hardwired or wireless systems. That means you can replace a worn cable at a fraction of the cost of replacing the entire mic. You can afford to keep extra cables in your kit for emergencies and you can use the same mic on multiple wireless systems simply by purchasing the appropriate cables. E6 cables and E2 cables are not interchangeable. The E2 Cable is 5 feet in length and has a 1.5mm aramid-reinforced cable.
