Title: Not much good for voices
Review: I didn't expect a lot, so I can't say I'm disappointed, and this might work for some things. For instance, if a person was profoundly deaf and couldn't hear a knock at the door, the beep of the microwave oven, or a car honking at them as they wandered through traffic, this would probably make a real difference.However, for speech it doesn't help, at least in my case. It actually does amplify the speech, but if you can't read lips it will be hard to understand what's going on... sounded so distorted that if I listened with my eyes closed and my finger in my "good" ear, I couldn't understand anything being said around me. I could tell they were talking, but that's all. I think this may give the illusion of hearing better, since there IS sound coming out of it, but for understanding speech it isn't useful.
