I didn’t get a carrying case with my order of Phonak I90 Spheres from Direct Hearing. Amazon is selling an official Phonak carrying case on Amazon that works very well (traps HAs from sliding around with central foam cushion in lid). Here’s a picture of what it looks like with my Spheres with cShell receivers in the case.
The case easily and unnoticeably fits in a pants pocket. A time or two I’ve wondered, “What did I do with it?!” Oops! It’s been in my pants pocket all along…
