The Wouxun HEO-023 is a light and flexible earpiece with a waterproof connector for Q and S Series waterproof radios. It has an around-the-ear "C" ring style loop to hold the earpiece comfortably in place. The earpiece rests against the outside of the ear and is reversible to work in either the left or right ear. The heavy duty Kenwood style (K1) connector is especially designed for protection against dust and water ingress. Works with Wouxun KG-Q10H, KG-S72C, KG-S74A, KG-S84B, KG-S86B and KG-S88G waterproof two way radios.
