A hearing aid has a plurality of microphones mounted in an array on a headband which extends from one ear over the top of the head to the other ear. The headband is flexible and adjustable in length. The headband has circuitry that can be switched among a directional monaural mode, a binaural mode, and a combination mode that provides both directionality and binaurally. Ganged controls are provided on the headband for both tone and volume. An external jack is provided on the headband to allow for the introduction of radio or recorded music from a personal stereo.
