I did this once, about 15 or so years ago with some ReSounds.
Now before I put my head under the shower, I look at the shower head and stroke the tops of my ears three times as I count one, two, three.
I made this a habit, and do it every time. If the aids are in, I’ll feel them.
At $6,000 or so, it’s not anything I want to soak again.
