A curable composition and method for producing a tear resistant, yet soft and deformable in-the-ear product yielding the user greater comfort and durability. The curable composition incorporated into a hearing aid apparatus provides a deformable, yet tear resistant housing, which may be mated to a soft tip component. The hearing aid housing provides better comfort, durability and acoustic performance for a variety of ear canal shapes. The curable composition that provides these properties includes at least one urethane acrylate oligomer, at least one reactive diluent and a cure system. The composition when cured desirably produces a tear strength of at least about 75 pli and a hardness of about Shore A 60 to about 75.
