Abstract

Embodiments of the invention provide for a headset and system including a portable device, wherein the headset includes an electrically conductive band configured to engage a portion of a head of a user and coupling together a headpiece and an earpiece assembly. The headpiece includes an electrically conductive portion that is configured to engage and electrically couple to the user'"'"'s head. The headpiece is electrically coupled with the conductive band. The earpiece assembly is coupled with the conductive band to engage an ear of a user and has a ground conductor that is electrically coupled between the conductive band and a portable device for coupling the portable device to the head of a user for reducing electrostatic discharge at the head of the user of the portable device.
