Very feeble and not so effective
I got this one for my grandmother who because of her age needed something to amplify sound. This one was not at all effective. She told that even after full charge it was not as effective as she thought it might be. I got another person test it whose hearing is better than her's. He also mentioned that it was not great even for him. It was ok, but not super effective. So I was disappointed with my purchase. I will not recommend it.
