Those silver hearing aids jump out at me every time I see somebody wearing them. I don’t think that grey hair disguises them very well.
I get black hearing aids. I wear glasses and pick frames that are dark. The hearing aids sit next to the bows on the frames and according to my wife they blend in reasonably well.
In the end, when you are a guy in my age group you don’t fret a lot about things like this. It is just so great, living in today’s high tech world and having a solution that keeps me in normal conversation and able to hear the birds sing. I cringe when I imagine what it must have been like for the likes of Edison or Beethoven and millions of others as they gradually lost their hearing.
