1. A system, comprising:
a first earbud including a first directional antenna operable at a first frequency and having a first radiation pattern radiating away from a zone that is sensitive to electromagnetic radiation; and
a second earbud including a second directional antenna operable at the first frequency and having a second radiation pattern radiating away from the zone, wherein the zone is defined by a region between the first earbud and the second earbud when worn by a user.
