Here’s a picture of my right ear wearing the ReSound M&RIE receiver in a custom mold made for my right ear. The mic on the M&RIE receiver can be seen on the receiver just below where the wire enters the receiver and the mic is surrounded on all sides by the lip on the mold opening and recessed a few mm into that opening. The molds are actually very translucent silicone. The dark appearance is from the relative darkness of my interior ear canal. (Click on image to enlarge).
