Abstract
A hearing protection device is presented. The device has a first earmuff connected to a second earmuff by a connector. Each of the first and second earmuffs are configured to receive an ambient sound and provide a dampened ambient sound to a wearer. The device also has a cable, with a cable length, that extends from the first earmuff to the second earmuff. The cable is coupled to the connector by a connection assembly. The connection assembly comprises a plurality of connection mechanisms arranged in a connection plan. Such a hearing protection device gives more freedom of placing the cable in a compact arrangement.
