    "Starting in my 40s, I have seen (I suppose “heard” is a better verb) major improvements: moving from analog to digital instruments, more compact and discrete devices, marriage to smartphones for crisp binaural reception of telephone calls, and rechargeable batteries (no longer a daily chore of fastening little batteries into the devices), and the perpetual monitoring of battery health so you wouldn’t loose you hearing halfway through a lecture or performance. ...First thing we wondered when we saw the unit was why it was so big when hearing aids are so small. The whole thing is about the size of a really large coffee mug. "
