ABSTRACT:
A collapsible hearing device comprising a base housing and a pair of jointed elongated extension arms constructed and arranged with pivots so located that when said arms are unfolded outward, a pair of earphones fixed to a distal end of each arm engages the ears of a user, and when said arms are folded inward, they essentially hug at least a portion of the perimeter of the base housing and form a structure with the base housing sufficiently small to fit into a storage case whose size approximates that of an eyeglass case. Switch means is provided to automatically disengage a power source when the device is folded for storage and to cause the device to be energized when the device is unfolded for use. Optionally, the base housing may have lower corner portions recessed in outline to receive said earphones when said arms are folded inward.
