The device (FIG. 1) is attached to a pair of binoculars or a telescope and consists of one or more directional microphones, microphone structures or sets of microphones, a microphone and headphone amplifier and a pair of headphones, the directional microphone structures (2, 3) and the amplifier unit (4) with the headphones (7) being attached to the binoculars (1) by suitable means. An audio signal can be supplied from the amplifier to an external recording device, or a recording device may be integrated with the device of the invention. Used together with a pair of binoculars or a telescope, the device provides a light and easy-to-use means of audiovisual observation of distant objects, and when provided with an integral or external tape recorder it is also suited for amateur use for the recording of wildlife sounds.
