As requested. A photo of my Phonak Marvel Link HA and my Advanced Bionics brand CI processor and magnet. I chose the teal color because I love it. They certainly offer more blendable colors! I am one who says I would wear an antennae if it helps me hear better.
Cochlear and Med El brands both offer off ear versions that look like a thicker quarter size disk. Like my magnet but a bit larger. Many prefer this look. I wanted the benefit of improved hearing that the Advance Bionics T mic offers- that is the small antennae like thing on the end of the CI. It sits within the natural curve of the ear to pick up sound in a way that takes advantage of the ear shape. I also wanted hands free phone calls and extra device free blue tooth. Both are awesome. I forget I am wearing them.
