I purchased the Kirkland Signature 6.0 as my first pair of hearing aids. They sounded tinny and they made my own voice sound as if it were coming through a megaphone.
I could have overlooked that if they had had a tinnitus therapy feature, but what really made me mad is the lack of durability. I went hiking once with my two week old hearing aids and after 1 hour, they quit working! They weren't covered in sweat or anything. This is intolerable as I'm a very active person.
