Abstract: Apparatus and methods for reducing cross talk between electrical ports are described. An electronic device comprises a housing for electronic circuitry and has a plurality of ports for connecting electrical devices. Each port includes a connector connected by at least one electrical connection to the electronic circuitry. A connector shield is arranged to provide an electrically conductive loop around which an induced electrical current can flow to reduce cross-talk between ports. A shielding can is part of the connector shield and includes a body formed of a folded sheet of electrically conductive material and an electrical contact for electrically connecting the body to a connector. A face of the body defines a first aperture shaped to receive the connector so that the shielding can may be arranged about the connector to form a part of the electrically conductive loop.
