A hearing aid sleeve is made from a pliable and flexible rubber material. The sleeve is configured to minimize acoustic feedback in an ear canal by restricting movement of a hearing aid relative to the ear canal. The hearing aid sleeve includes a pliable rubber body configured to flex to the contours of an ear canal, the rubber body having an outer surface. The opposing ends of the sleeve form a tapered contour. An aperture passes from a first end to a second end. The aperture is configured to accept contact with the hearing aid. The outer surface of the body is configured to flex to the contour of the ear canal and grip the surface of the ear canal, thereby increasing the compressive forces around the hearing aid sufficient to minimize acoustic feedback.
