The Digi SP boasts a lead in the industry by being the lightest weight ear contour available, coming it at approximately 12 g. You can easily forget about it when it is in your ear because of its support by its antenna and hook. It is design to perfectly adapt to any ear morphology, both adult and child, with its clean, slender design. It comes standard with two wide range acoustic microphones that allow you to hear a large variety of sounds that are not distorted. Connecting audio accessories is a breeze with help from the "AUX" socket. You connect the accessories directly on the contour -- no added wires or metal feet required! Several programming options make it easy for you to adapt your hearing to each environment you are in. You can select from up to four programs.
