I had to get hearing aids last year. I can now hear birds and critters walking in the leaves and coyotes singing at dusk. Only down side outdoors is the wind interference and I worry about losing one or both of them. I got a mid grade set in terms of cost that can be controlled with an app on my phone. There is an outdoor setting and they are fully adjustable for direction for 360 degrees.
Without them, I really miss a lot of sounds.
PS – Grumpy, I know how the deer know what you posted here. They are psychic mind readers here in my woods.
