Wow great..!
Hello hunter friend, what a good product you present to us today.
I read your post and I remembered my grandpa, he has problems listening, I really do not like that I have to raise his tone so he can listen to me; This product is really suitable and super useful for grandparents who have hearing impairment; besides that they look comfortable because they are not inside but out of the ear.
Now I can only say: Congratulations and keep going
