A headset has a first and an optional second earpiece 12, 16 respectively coupled to a plug 30 via first and an optional second conductors 14, 20, 18, 22. An antenna loop section 36 has a first loop section 31 at least partially bound to a portion of the first conductor 20, and a second loop section 33 bound to at least a portion of the second conductor 22. Where bound, the first conductor and first loop section may be coaxial or side-by-side. The loop sections include inductors 42,44, and the conductors include ferrite rings 38,40 near the earpieces. A connector 24 mechanically holds the first and second conductors in proximity to one another, and also includes a conductive bridge 34 to electrically couple the first and second loop segments, which may be via a contact connection or a capacitive connection. Audio and RF signals are separated by frequency in a device 50 to which the headset is coupled.
