My dad's hearing is pretty bad, always got the "what", "huh", every time you talk to him. He looked into cheap hearing aids and they were $698 each, no warranty what so ever. So decided to give these a try, what a life-changer for him. Now he can hear so much better and even is speaking softer now. I took him about a week to find the right settings that suit his needs. Are they worth the money? Woah, yes! Batteries last a few weeks. When he removes them, he pulls the battery door open to save power on the battery cell. Highly recommended.
