Rc, I have worn hearing aids for several years now, They have got better and smaller.
The set I have now is {Resound} brand. I have had good service from them and they do get put through the ringer, I work each day in our body shop , dirty , dusty , loud.
My main complaint is as tech improves and the aids get smaller so has the batteries, also the bells and features the shorter the life span of the batteries. I get aprox 5 days on a pair of batteries.
Most of the aids today self mute at loud noise.
I have settings for work, conversation , movies / bar type setting. I can also crank the up or dumb them down by the tiny push button.
If you ever get caught out in a hard rain, take them out and put them in your pocket, Mine will stand some moisture but not a hard rain.
Also add them onto your home owners insurance policy before the factory warranty expires.
Mine cost right at $3,800 for the pair this last set. like anything the price goes up over time.
